High density capacitors exhibit high ripple current capability
8 August 2023 
The Epcos B43657 aluminium electrolytic capacitor series have high ripple current capability of up to 8.54A (120Hz, 60°C). The capacitors achieve a service life of at least 2000 hours at a maximum operating temperature of 105°C, claims TDK. They also cover a rated voltage range from 450 to 475V DC with capacitance values from 120 to 1250μF.
The compact capacitors are offered in case sizes as low as 22 x 25mm up to 35 x 60mm. They are designed with snap-in terminals for ease of installation.
The RoHS-compatible capacitors are intended for use in high-end switched-mode power supplies and power supplies for industrial and telecommunications applications. In addition, they are well-suited for UPS (uninterruptible power supplies), photovoltaic inverters and frequency converters.
