A new series of low impedance, automotive grade miniature aluminum electrolytic capacitors from Vishay Intertechnology Inc. combines high ripple currents up to 3.36 A with high temperature operation to 125° C and very long useful life of 6,000 h at 125° C.
Compared to previous-generation solutions, Vishay BC components 190 RTL 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

Featuring radial leads and a cylindrical aluminum case with pressure relief, insulated with a blue sleeve, the 190 RTL series offers rated voltages up to 50 V, capacitance from 100 µF to 6800 µF, and low maximum impedance down to 0.017 Ω. 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 high temperature industrial, automotive, telecommunications, medical and military applications.
Samples and production quantities of the 190 RTL series are available now, with lead times of six weeks. Pricing for U.S. delivery only starts at $0.50 per piece.
