TDK Releases New Compact High CV, High Ripple Current Snap-In Aluminum Electrolytic Capacitors

30.10.2020
Reading Time: 2 mins read
A A

TDK Corporation presents the new EPCOS aluminum electrolytic capacitor series B43647* with snap-in terminals. Thanks to their outstandingly high CV product, they are ideal for highly compact solutions in power electronics.

The capacitors are designed for a maximum operating temperature of 105 °C; at a rated voltage of 450 V DC and maximum ripple current, they reach a useful life of 2000 h. A capacitance range from 120 µF to 1000 µF is offered in case sizes ranging from 22 mm x 25 mm to 35 mm x 55 mm. Another special feature is the high ripple current capability up to 7.22 A (100 Hz, 60 °C).
