Facing heat, humidity, and space limits in power designs? Maybe this compact capacitor will help you make systems smaller and more reliable. Read more!
Design engineers working on automotive, energy, or industrial power systems now have a capacitor option that combines high ripple current handling, long term humidity resistance, and compact size. The Vishay Roederstein MKP1848e is an AEC Q200 qualified DC Link metallized polypropylene film capacitor built to operate in demanding conditions, including high temperatures up to +125 °C.
For engineers designing automotive systems, this capacitor supports applications such as on board chargers, powertrains, HVAC units, e compressors, and DC to DC converters. In energy and industrial projects, it serves fast chargers, solar inverters, hydrogen electrolyzer rectifiers, battery storage, UPS, and motor drives. By combining heat tolerance with strong resistance to humidity, the device helps extend system reliability while reducing failure risk.
The MKP1848e is offered with capacitance values from 1 µF to 140 µF and voltages from 500 VDC to 1300 VDC. With ESR as low as 1.0 mΩ, it delivers ripple current up to 44.5 A, which is 25 percent higher ripple current density than earlier solutions of the same size. Compact pitch options down to 22.5 mm and optimized footprint enable space savings of up to 40 percent in volume and 15 percent in pitch at 500 VDC and 900 VDC.
For EV and PHEV system designers, the capacitor withstands 250 VDC to 800 VDC operation at +125 °C for limited time, meeting typical traction inverter and charging requirements. It also passes rigorous reliability tests, including 1344 hours of temperature humidity bias at 60 °C and 93 percent relative humidity, and 1000 temperature cycles from -40 °C to +125 °C with 30 minute dwells.
Engineers can also request customized terminals, making it easier to integrate the capacitor into specific layouts or compact assemblies. By combining high electrical performance with environmental robustness, the MKP1848e helps design teams push for smaller, more efficient, and longer lasting power conversion systems.
