Automotive grade aluminium capacitors increase design flexibility and reliability

Vishay Intertechnology has introduced two new series of automotive grade, surface-mount aluminium electrolytic capacitors that combine high voltages up to 450V with operating temperatures up to +125C and useful life up to 6,000 hours for automotive and industrial applications.

The high voltage range of Vishay BCcomponents 152 CME and 192 CTX series capacitors gives designers greater design flexibility, while their high-temperature capabilities and extended useful life increase reliability for demanding applications in harsh environments. As polarised aluminium electrolytic capacitors with a non-solid electrolyte, the AEC-Q200 qualified devices are suited for filtering, smoothing, and buffering in power supplies and portable chargers for EVs and industrial equipment.

The series provide capacitance values from 2.2µF to 33µF in seven case sizes ranging from 10mm x 10mm x 10mm to 18mm x 18mm x 21mm. The RoHS-compliant capacitors offer charge and discharge-proof performance with no peak current limitation, provide for lead (Pb)-free reflow soldering in accordance with JEDEC J-STD-020, and offer vibration-proof performance in four and six-pin versions.
