Vishay Intertechnology, Inc. has released a new AEC-Q200-qualified DC-link metallized polypropylene film capacitor designed for harsh conditions in automotive, energy, and industrial applications. The Vishay Roederstein MKP1848e DC-link film capacitor operates up to 125°C and withstands temperature humidity bias (THB) in accordance with Grade III of IEC60384-16 ed.3 – 60°C /93% relative humidity for 1,344 hours at rated voltage.

Thanks to its high temperature operation and resistance to high humidity, the automotive-grade DC-link film capacitor is suited for automotive power conversion applications such as on-board chargers, power trains, HVAC systems, e-compressors, and DC/DC converters. It also meets the stringent requirements of energy and industrial power conversion applications such as fast chargers, solar inverters, rectifiers for hydrogen electrolyzers, battery storage systems, motor drives, and UPS.
Key specifications for the MKP1848e include ripple current up to 44.5 A, a capacitance range from 1 µF to 140 µF, low equivalent series resistance (ESR) down to 1.0 mΩ, and rated voltages from 500 VDC to 1,300 VDC. The devices provide 25% higher ripple current density than previous-generation solutions with the same volume. The footprint and pitch options down to 22.5 mm deliver volume reductions up to 40% and 15%, respectively, at 500 VDC and 900 VDC.
The MKP1848e withstands operating voltages from 250 VDC to 800 VDC at 125°C for a limited time to meet the standard high-voltage levels of electric (EV) and plug-in hybrid electric vehicles. It also offers high thermal shock capabilities, withstanding 1,000 temperature cycles over the temperature range of -40°C to 125°C, with a 30-minute dwell time for each temperature extreme, according to Vishay.
Samples and production quantities of the MKP1848e are available now. It is available with custom terminals on request. Lead time is 10 weeks. Pricing for U.S. delivery starts at $1.00 per piece.
