Vishay Releases New Automotive Grade Miniature Aluminum Capacitors Featuring High Ripple Current and Long Life

20.10.2020
Reading Time: 2 mins read
A A

Vishay Intertechnology introduces a new series of low impedance, Automotive Grade miniature aluminum electrolytic capacitors that combines high ripple currents up to 3.8 A with high temperature operation to +105 °C and very long useful life of 10,000 hat 105°C.

Compared to previous-generation solutions, the 170 RVZ series capacitors offer lower impedance and 10 % to 15 % higher ripple current. This allows designers to utilize fewer components, increasing design flexibility and saving board space. Available in smaller case sizes that previous-generation solutions.
