Jianghai CD135 BP Screw Terminal Aluminum Electrolytic Capacitors
Jianghai CD135 BP capacitors are screw terminal aluminum electrolytic capacitors designed for industrial power equipment where high capacitance, secure mechanical connections, and clearly defined electrical ratings are required. The CD135 BP series is identified in Jianghai documentation as a standard 85°C screw terminal capacitor family with a rated load life of 2000 hours at 85°C. Published applications include UPS equipment, drives, and inverters.
Apexon Supply supports industrial buyers sourcing Jianghai CD135 BP capacitors for new procurement, maintenance, repair, replacement, and difficult-to-find requirements. Buyers can also review the broader Jianghai capacitor collection for other JiangHai aluminum electrolytic capacitor families. Because CD135 BP includes many voltage, capacitance, case-size, mounting, and terminal combinations, we recommend confirming the complete part number before ordering rather than selecting only by capacitance and voltage.
Jianghai CD135 BP Series Overview
CD135 is the Jianghai series designation, while BP is the corresponding series code used within the screw-terminal capacitor part-number system. The series is specified as a standard 85°C screw-terminal aluminum electrolytic capacitor family. The supplied CD135 BP catalog also identifies RoHS compliance and lists UPS, drive, and inverter equipment among the intended applications.
The catalog contains a large number of individual electrical and mechanical combinations. Depending on the exact order code, buyers may need to distinguish between rated voltage, surge voltage, capacitance, ESR, rated ripple current, case diameter and length, mounting arrangement, and terminal configuration. These values are model-specific and should not be assumed to be identical throughout the CD135 BP range.

CD135 BP Voltage and Capacitance Options
The CD135 BP ratings tables cover many voltage and capacitance combinations rather than a single standardized capacitor size. For industrial sourcing, the required electrical rating should therefore be matched to the exact catalog order code. The supplied ratings include 350V, 400V, and 450V configurations across multiple capacitance values and physical sizes.
350V CD135 BP Capacitors
The 350V section of the CD135 BP catalog includes values from hundreds of microfarads through much larger capacitance ratings. Examples include 3300µF, 4700µF, 6800µF, 10000µF, 12000µF, 15000µF, and other configurations. Case diameter, case length, ESR, and ripple-current rating change with capacitance, so two 350V CD135 BP capacitors should not be treated as mechanically or electrically interchangeable simply because they belong to the same series.
400V CD135 BP Capacitors
The catalog also provides multiple CD135 BP 400V configurations. Representative ratings include 3900µF, 4700µF, 5600µF, 6800µF, 8200µF, 10000µF, 12000µF, and 15000µF. These variants use different case dimensions and have different published ESR and ripple-current values. When replacing an installed capacitor, verify the full order code and mechanical envelope in addition to the 400V rating.
450V CD135 BP Capacitors
CD135 BP 450V versions are shown with capacitance values including 470µF, 680µF, 820µF, 1000µF, 1200µF, 1500µF, 1800µF, 2200µF, 2700µF, 3300µF, 3900µF, 4700µF, 5600µF, 6800µF, 8200µF, 10000µF, and 12000µF in the reviewed catalog. Not every historical catalog configuration should be assumed to have the same current sourcing status, so the complete part number remains the best starting point for an RFQ.
Representative Jianghai CD135 BP Catalog Codes
The examples below are representative entries from the reviewed CD135 BP ratings table and are not an exhaustive list. The catalog part-number system may add mounting and terminal-option characters to the base order code.

How to Select a Jianghai CD135 BP Capacitor
For replacement and industrial procurement projects, matching only the brand and series is not sufficient. The CD135 BP ratings tables contain substantial differences between models. Confirm the following information whenever possible:
- Complete part number: Use the entire code from the capacitor body, original equipment documentation, or current datasheet.
- Rated voltage: Confirm the required operating voltage rather than substituting a different voltage class without engineering review.
- Capacitance: Match the specified nominal capacitance and tolerance required by the equipment design.
- Surge voltage: The catalog provides a surge-voltage value or code for each voltage class. This should be checked separately from rated voltage.
- ESR: Typical ESR values are published by model at specified test conditions and vary substantially across the series.
- Ripple current: Verify the rated ripple-current requirement and its test frequency and temperature conditions.
- Dimensions: Confirm case diameter, case length, terminal spacing, and available installation clearance.
- Mounting arrangement: The CD135 part-number system includes different mounting options such as bolt mounting and bracket configurations.
- Terminal option: Terminal details can be represented by additional suffix characters and should be checked against the original installation.
- Operating conditions: Ambient temperature, cooling, ripple-current frequency, and actual electrical load can affect capacitor selection and operating life.
Ripple Current, Temperature and Service-Life Considerations
The CD135 BP datasheet provides frequency coefficients for ripple current as well as ambient-temperature coefficients and a lifetime diagram. These references are important because a ripple-current rating stated at one frequency or temperature should not automatically be applied to different operating conditions without using the manufacturer's design information.
The stated 2000-hour load-life rating is a defined catalog test rating at 85°C; it should not be interpreted as a prediction that every capacitor will fail after 2000 hours or as a guaranteed service life in every machine. The manufacturer's lifetime information shows that operating temperature and actual ripple-current loading are relevant to expected operating duration. For replacement projects, use the current datasheet and actual equipment operating conditions when evaluating suitability.
The catalog also defines leakage-current testing after application of rated voltage and provides dissipation-factor and ESR information for individual ratings. These parameters can be particularly important when an existing capacitor is part of a power conversion system in which thermal loading, ripple current, and physical installation are tightly constrained.
Industrial Applications for CD135 BP
Jianghai identifies UPS, drive, and inverter equipment as applications for the CD135 BP series. In these systems, screw-terminal electrolytic capacitors may be selected where the equipment design calls for a particular combination of capacitance, voltage rating, ripple-current capability, ESR, and mechanical construction.
For maintenance teams, the application name alone is not enough to select a replacement. Two inverter systems may use different CD135 ratings, and two capacitors with the same voltage and capacitance may still differ in dimensions, ripple-current capability, mounting arrangement, or terminal configuration. Whenever an existing capacitor is being replaced, the original label and full order code should be treated as primary identification information.
CD135 BP Replacement and Obsolete Part Sourcing
Industrial drives, UPS systems, and inverter equipment can remain in operation for many years, which means maintenance teams may encounter older CD135 BP order codes, catalog revisions, or configurations that are no longer easy to locate through normal local channels. Apexon Supply can help review the exact Jianghai part number, capacitor label, datasheet, dimensions, electrical ratings, and equipment information before checking sourcing options.
Where the exact original CD135 BP model is available through an appropriate supply channel, Apexon can coordinate sourcing based on the confirmed order code and quantity. Availability should always be checked at the time of inquiry and is not guaranteed simply because a model appears in a historical catalog or online reference.
If the exact capacitor cannot be sourced, a possible alternative should only be considered after the necessary electrical and mechanical parameters are compared. Voltage, capacitance, ripple-current rating, ESR, temperature capability, case dimensions, mounting, terminal arrangement, and installation requirements may all affect suitability. A higher-temperature or longer-life Jianghai series should not automatically be treated as a drop-in replacement for CD135 BP.
Jianghai documentation positions CD136 PK as a 105°C screw-terminal series and CD138 PC as a longer-life series relative to CD135 BP. These relationships can help identify families worth investigating, but they do not establish automatic interchangeability. Any substitute should be technically reviewed and approved for the equipment before installation.
