Jianghai CD136 PK Screw Terminal Aluminum Electrolytic Capacitors
Jianghai CD136 PK capacitors are screw terminal aluminum electrolytic capacitors designed for industrial power electronics operating at temperatures up to 105°C. Jianghai documentation positions the CD136 PK series for professional inverters and power supplies, with a broad combination of voltage, capacitance, ripple-current, ESR, case-size, and mounting options for demanding power-conversion applications.
Apexon Supply supports industrial buyers sourcing Jianghai CD136 PK capacitors for equipment production, maintenance, repair, replacement, and difficult-to-find requirements. Buyers can also browse the broader Jianghai aluminum electrolytic capacitor collection for related JiangHai capacitor models. Because CD136 PK covers many electrical and mechanical configurations, the complete order code should be verified before purchasing rather than selecting a capacitor by voltage and capacitance alone.
Jianghai CD136 PK Series Overview
CD136 is the Jianghai series designation and PK is the corresponding series code used in the screw-terminal capacitor order-number system. The series is a 105°C screw-terminal aluminum electrolytic capacitor family intended primarily for professional inverter and power-supply applications.
The reviewed CD136 PK documentation divides the operating range into two main voltage groups. Models rated from 25V through 100V are specified for an operating temperature range of -40°C to +105°C, while models rated from 160V through 450V are specified from -25°C to +105°C. Across the documented series, capacitance values extend from 220µF to 330000µF, depending on voltage class and construction.

CD136 PK Voltage and Capacitance Range
The CD136 PK family is not a single capacitor design. Jianghai ratings tables contain numerous voltage and capacitance combinations, each with its own ESR, rated ripple current, case diameter, length, and order code. This makes series-level identification useful for product discovery, but exact model identification remains essential for purchasing and replacement work.
25V to 100V High-Capacitance CD136 PK Models
The lower-voltage portion of the CD136 PK range includes very high capacitance values. At 25V, the documented range extends up to 330000µF, while the 35V group includes values up to 220000µF. Additional groups include 50V, 63V, 80V, and 100V configurations with multiple capacitance and case-size choices.
Representative Apexon model pages include the Jianghai ECG1EPK334MF131 330000µF 25V CD136 PK capacitor, the Jianghai ECG1VPK224MF131 220000µF 35V CD136 PK capacitor, and the Jianghai ECG2APK473MF131 47000µF 100V CD136 PK capacitor.
160V to 250V CD136 PK Models
The series also includes 160V, 200V, and 250V configurations. As voltage increases, the available capacitance range and physical construction change accordingly. The ratings table includes configurations from hundreds of microfarads through several thousand microfarads, with selected high-capacitance models reaching substantially higher values within these voltage classes.
For this part of the range, buyers should pay particular attention to the case diameter and length because capacitors with similar electrical ratings may use different mechanical envelopes. Ripple-current capability and ESR also vary by individual order code.
400V CD136 PK Capacitors
The 400V class is especially relevant to professional power-conversion equipment. Documented capacitance values include 1000µF, 1200µF, 1500µF, 1800µF, 2200µF, 2700µF, 3300µF, 3900µF, 4700µF, 5600µF, 6800µF, 8200µF, and 10000µF, with different case-size options for selected capacitance values.
For example, the Jianghai ECG2GPK332MD130 3300µF 400V CD136 PK capacitor is documented with a 64 × 130mm case, while the Jianghai ECG2GPK472ME130 4700µF 400V CD136 PK capacitor uses a 77 × 130mm case. This illustrates why physical dimensions must be checked independently from voltage and capacitance.
450V CD136 PK Capacitors
The documented 450V group includes capacitance ratings from 220µF through 5600µF. Representative ratings include 330µF, 470µF, 680µF, 1000µF, 1500µF, 2200µF, 3300µF, 4700µF, and 5600µF.
A representative model is the Jianghai ECG2WPK222MD115 2200µF 450V CD136 PK capacitor. Its reviewed model data specifies a 500V surge rating, 33mΩ typical ESR at 20°C and 120Hz, 7.3Arms rated ripple current at 105°C and 120Hz, and a 64 × 115mm case. These values apply to this specific model and should not be generalized to other 450V CD136 PK capacitors.

| ECG2GPK332MD130 | 400V | 3300µF | 20mΩ | 9.7Arms at 105°C, 120Hz | 64 × 130mm |
| ECG2WPK222MD115 | 450V | 2200µF | 33mΩ | 7.3Arms at 105°C, 120Hz | 64 × 115mm |
Understanding the CD136 PK Part Number
Jianghai screw-terminal order codes identify multiple product characteristics. A representative 400V, 3300µF model is ECG2GPK332MD130. Within this code, PK identifies the CD136 series, while other portions identify parameters such as capacitor type, rated-voltage code, capacitance, tolerance, diameter, and length. Additional characters may be used for mounting and terminal configurations.
Because complete order-code construction can vary by catalog revision and selected mechanical option, procurement teams should use the full code printed on the existing capacitor or specified by the equipment manufacturer. An abbreviated reference such as “CD136 400V 3300µF” may not uniquely identify every mechanical configuration.
How to Select a Jianghai CD136 PK Capacitor
For new designs and replacement projects, several parameters should be confirmed before selecting a CD136 PK model:
- Complete part number: Record every character from the existing capacitor label or approved bill of materials.
- Rated voltage: Confirm the required DC voltage class and do not rely only on physical similarity.
- Surge voltage: Verify the surge rating associated with the exact model and voltage class.
- Capacitance: Confirm nominal capacitance and required tolerance.
- ESR: Check the applicable ESR value and the specified temperature and frequency conditions.
- Ripple current: Compare the required ripple-current capability at the relevant frequency and temperature.
- Case dimensions: Check diameter, body length, available clearance, and terminal spacing.
- Mounting style: Confirm whether the installation requires bolt mounting, a bracket arrangement, or another specified construction.
- Terminal configuration: Check terminal size and option codes against the existing assembly.
- Operating environment: Consider ambient temperature, cooling, vibration, installation position, and actual electrical loading.
- Datasheet revision: For existing equipment, verify that the specifications correspond to the revision and exact part number being replaced.
Ripple Current, ESR and Temperature Considerations
The CD136 PK documentation provides different ripple-current frequency coefficients for different voltage ranges. This is important because a ripple-current rating specified at 120Hz should not automatically be treated as the same value at another operating frequency. Temperature also affects permitted loading and expected operating life.
Likewise, ESR is model-specific. Within a single voltage class, changes in capacitance and case size can produce materially different ESR and ripple-current values. For that reason, an alternative capacitor with the same voltage and capacitance should not automatically be considered electrically equivalent.
The series documentation also distinguishes between lower-voltage models rated for operation down to -40°C and higher-voltage models beginning at -25°C. Buyers should therefore confirm the temperature range of the exact model instead of assuming every CD136 PK capacitor has identical environmental limits.
CD136 PK Lifetime and Datasheet Revision
Lifetime terminology deserves particular attention when comparing CD136 PK documentation. Earlier CD136 PK literature and several reviewed Apexon model pages specify a 2000-hour load-life rating at 105°C. Updated Jianghai documentation identifies the current CD136 PK series with a 4000-hour useful-life figure at 105°C while retaining a 2000-hour standardized load-life test within the qualification table.
These figures describe different lifetime definitions and documentation revisions and should not be treated as interchangeable marketing claims. For maintenance and replacement work, the safest approach is to identify the exact part number and compare the applicable current or historical datasheet with the requirements of the equipment. Apexon can assist with this document and model review during the sourcing process.
Industrial Applications for CD136 PK
Jianghai identifies professional inverters and power supplies as primary applications for the CD136 PK series. In these systems, screw-terminal electrolytic capacitors may be selected where the circuit requires a specific combination of DC voltage rating, capacitance, ESR, ripple-current capability, temperature performance, and mechanical installation format.
Application type alone does not establish compatibility. Two inverter platforms or power supplies can use very different capacitor ratings even when their overall function is similar. For replacement work, the installed capacitor label, complete part number, equipment documentation, physical dimensions, and electrical requirements should be reviewed together.
CD136 PK Replacement and Difficult-to-Find Sourcing
Industrial power equipment can remain in service for many years, and older CD136 PK order codes may continue to appear in inverter cabinets, power supplies, production machinery, and maintenance inventories long after the original equipment was installed. During this period, catalog revisions, terminal options, mounting arrangements, sourcing conditions, and series documentation can change.
Apexon Supply can help review the complete Jianghai part number, capacitor label, existing datasheet, electrical specifications, case dimensions, and equipment information before checking sourcing options. If the requested original model can be located through an appropriate supply channel, sourcing can be coordinated based on the confirmed order code and quantity. A model's appearance in a catalog or on an existing product page does not guarantee current availability.
If the exact CD136 PK capacitor is difficult to obtain, a possible alternative should only be evaluated after the relevant electrical and mechanical parameters are compared. Rated voltage, capacitance, ripple-current capability, ESR, temperature rating, case diameter, body length, mounting arrangement, terminal construction, and equipment requirements can all affect suitability.
Other Jianghai screw-terminal series may have different temperature, lifetime, or current characteristics, but those differences do not establish automatic interchangeability. Any proposed substitute should be reviewed technically and approved by the customer, equipment manufacturer, or qualified engineering personnel before installation.
