Vishay Intertechnology Inc
Vishay Intertechnology Inc introduced a new series of low impedance Automotive Grade miniature aluminum electrolytic capacitors that delivers higher performance in smaller case sizes than previous-generation solutions. The Vishay BC components 172 RLX series combines high ripple currents up to 4.9A, high temperature operation to +105 °C, and very long useful life to 10 000h in 14 case sizes ranging from 10mm by 12mm to 18mm by 40mm.
Compared to previous-generation solutions, the AEC-Q200 qualified capacitors offer lower impedance, higher capacitance for a given case size and voltage, and up to 54 % higher ripple current at the same capacitance-voltage (CV) rating in smaller case sizes. For example, while previous-generation solutions offer ripple current of 1100mA at a CV rating of 1000F / 10V in the 10mm by 16mm case size, the 172 RLX series delivers 1700mA in the 10mm by 12mm case size. This allows designers to utilize fewer components, increasing design flexibility and saving board space.
Featuring radial leads and a cylindrical aluminum case with pressure relief, insulated with a blue sleeve, the 172 RLX series offers rated voltages up to 50V, capacitance from 150µF to 15 000µF, and low impedance down to 0.011Ω at +20 °C. The devices 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, DC/DC converters, motor drives, and control units for industrial, automotive, telecommunications, audio-video, and electronic data processing (EDP) applications.
