Ultra-compact capacitor snaps into place

TDK Corporation has introduced the EPCOS B43657 aluminum electrolytic capacitor series with snap-in terminals. Specifications include: a >2000h service life at a maximum operating temperature of 105°C; rated voltage range from 450 to 475VDC; and capacitance values from 120µF to 1250μF. An important performance feature is ripple current capability up to 8.54A (120Hz, 60°C). The AlCap Tool can be used to calculate lifetime under application-specific conditions.

Case sizes range from 22 by 25mm to 35 by 60mm (D x H). Thanks to their reliability, these RoHS-compatible capacitors suit high-end switched-mode power supplies; industrial/telecommunications power applications; UPS systems; photovoltaic inverters; and frequency converters.
