MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) has introduced a new AEC-Q200 qualified DC-Link metallized polypropylene film capacitor engineered for demanding automotive, energy, and industrial power applications. The Vishay Roederstein MKP1848e is designed to withstand high temperatures, humidity, and voltage stresses while delivering greater efficiency in a compact form factor.
Built for operating conditions up to +125 °C, the MKP1848e provides ripple current handling up to 44.5 amps and passes temperature humidity bias testing in line with IEC60384-16 ed.3 standards at 60 °C and 93 percent relative humidity for 1,344 hours at rated voltage. These features make it well-suited for critical automotive systems, including on-board chargers, powertrains, HVAC units, e-compressors, and DC/DC converters.
The capacitor also targets energy and industrial applications, including solar inverters, battery storage systems, hydrogen electrolyzer rectifiers, fast chargers, UPS systems, and motor drives.
Offering capacitance values from 1 µF to 140 µF and low ESR levels down to 1.0 mΩ, the MKP1848e supports rated voltages from 500 VDC to 1300 VDC. Compared with earlier models, it achieves 25 percent higher ripple current density in the same volume, while its compact footprint reduces size by up to 40 percent at 500 VDC and 15 percent at 900 VDC.
For electric and plug-in hybrid vehicles, the device is built to tolerate operating voltages between 250 VDC and 800 VDC at +125 °C for limited periods. It also demonstrates strong thermal endurance, surviving 1,000 cycles between -40 °C and +125 °C with 30-minute dwell times at both extremes.
Vishay noted that the MKP1848e can also be supplied with customized terminals to meet specific design requirements, further extending its utility across a range of high-performance power conversion systems.
