TDK B43656 Aluminum Electrolytic Capacitors

TDK B43656 Aluminum Electrolytic Capacitors are designed for applications requiring high capacitance, long life, and high reliability. These capacitors are optimized for base cooling and high ripple current density, with some variants offering a life of 10,000 hours at 105°C. The B43656 large-size capacitors feature up to 56.1A at 100Hz high AC ripple currents and 85°C, and up to 100A in standard conditions. These large capacitors are RoHS-compatible and available with ±0.5mm tight length tolerance with a qualification based on the AEC-Q200 rev. E standard. The B43656 capacitors are suitable for on-board chargers, frequency converters, power supplies, industrial, wind power converters, solar inverters, and automotive applications.
