Vishay Intertechnology has introduced a new series of low impedance, Automotive Grade miniature aluminum electrolytic capacitors that combine high ripple currents up to 3.36 A with high temperature operation to +125 Â°C and very long useful life of 6,000 h at 125 Â°C.

Compared to previous-generation solutions, Vishay BCcomponents 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 case sizes, ranging from 10 mm by 12 mm up to 18 mm by 35 mm.

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 Î©. 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.
