New ultra-compact snap-in capacitors with extremely high capacitance density

TDK Corporation has released its new EPCOS B43657* aluminium electrolytic capacitor series with snap-in terminals. The capacitors attain a service life of at least 2000h at a maximum operating temperature of 105C and cover a rated voltage range from 450VDC to 475VDC with capacitance values from 120µF to 1250μF. An important performance feature is their high ripple current capability of up to 8.54A (120Hz, 60C). Accurate lifetime calculation under application-specific conditions is fast and simple with the online AlCap Tool.

Particularly significant is the extremely high capacitance density of the ultra-compact capacitors with case sizes from only 22mm x 25mm to 35mm x 60mm (D x H).

Due to their high reliability, these RoHS-compatible capacitors are perfect for high-end switched-mode power and power supplies for industrial and telecommunications applications. Also, they are ideal for UPS systems, photovoltaic inverters and frequency converters.
