TDK EPCOS B43456 & B43458 Screw Terminal Capacitors | Technical Guide
Share
The TDK EPCOS B43456 and B43458 series represent the pinnacle of "extremely compact" aluminum electrolytic capacitor design. Engineered for high-voltage industrial applications, these screw-terminal components offer a superior CV product, allowing for significant space savings in power electronics cabinets without compromising on ripple current capability.
Product Overview
Classified as long-life grade, these capacitors are designed for operation at up to 85 °C. The B43456 series is optimized for ring clip mounting, while the B43458 variant features a threaded stud. Both series utilize an all-welded construction for high reliability and low contact resistance.
Typical Applications
- Frequency converters and variable speed drives
- Wind power converters and solar inverters
- Professional industrial power supplies and UPS systems
Key Features & Benefits
- Extremely Compact: High CV product for maximum power density.
- Enhanced Safety: Available with Protection Against Polarity Reversal (PAPR) terminals.
- Long Useful Life: Exceeds 12,000 hours at rated conditions.
