Vishay introduces new miniature aluminum capacitors to increase design flexibility and save board space

Automotive Grade Devices Offer High Ripple Currents Up to 3.8 A, Operating Temperatures to +105°C, and Useful Life of 10,000 Hours at 105°C

Vishay Intertechnology, Inc. today introduced 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 up to 10,000 h at 105°C.

Compared to previous-generation solutions, Vishay BCcomponents 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. In addition, the AEC-Q200 qualified devices are available in smaller case sizes, ranging from 10 mm by 12 mm up to 18 mm to 40 mm.


  • Very long useful life: 4000 h to 10000 h at 105 °C, high stability, high reliability
  • Very low impedance and low ESR in smaller case sizes than the 150 RMI series
  • Excellent ripple current capability


  • Power supplies (SMPS, DC/DC converters) for general industrial, EDP, audio‑video, automotive, and telecommunications
  • Smoothing, filtering, buffering

Featuring radial leads and a cylindrical aluminum case, insulated with a blue sleeve, the 170 RVZ series offers rated voltages up to 63 V, capacitance from 100 µF to 6800 µF, and low impedance. The capacitors are charge- and discharge-proof.

As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the RoHS-compliant devices are ideally suited for smoothing, filtering, and buffering in switch mode power supplies and DC/DC converters for industrial, automotive, telecommunications, medical, and consumer applications.

Samples and production quantities of the 170 RVZ series are available now, with lead times of six weeks. More information please visit
