A series of Automotive Grade AC and pulse metallised polypropylene film capacitors for hybrid and electric vehicles has been introduced by Vishay Intertechnology. With a maximum operating temperature of +125°C (observing voltage derating), Vishay BCcomponents MKP385e series devices ensure compliance with IEC 60384-17 and AEC-Q200 Revision D.
They withstand temperature humidity bias (THB) testing of 60°C, 93% RH for 56 days at rated voltage.
The radial potted capacitors released today are designed to ensure high and stable pulse strength and ripple current capabilities over a long service life under harsh environmental conditions.
Offered in compact packages to increase density, the robust devices are ideal for onboard and inductive charging, battery management, and keyless systems; snubbering; resonant converters; and power supplies.
The MKP385e series is available in eight rated voltages from 400VDC to 2500VDC. Capacitors with voltage ratings of 630VDC and below feature a mono construction, while devices with voltages above 630VDC offer a series film construction.
The capacitors offer rated capacitance from 0.001µF to 15µF, low ESR down to 4mΩ, and high ripple current capabilities up to 19.3A.
RoHS-compliant, the devices can be customised by Vishay on request.
Samples and production quantities of the MKP385e series are available with a lead time of 10 to 13 weeks.
