KEMET C44U-M, C44P-R, and R75H series film capacitors

KEMET today  announces  three  new  series  of  metallizedpolypropylene dielectric film capacitors: C44U-M, C44P-R, and R75H. Constructed with an aluminium canister design, both the C44U-M and C44P-R series address the increasing demand  for  high-power  conversion  systems  in  green  energy  and  industrial applications. These capacitors also support power conversion in energy storage systems, IGBT and wide bandgap (WBG) semiconductor devices. The R75H series, a radial box pulsecapacitor, is similar in that it supports these applications, but also addresses the automotivesector with its high voltage, AEC-Q200 certified design.

The latest C44U-M series features a DC-Link and DC filter power film capacitor designed forhigh-power conversion systems applications in green energy, industrial, and energy storagesystems. It supports DC networks and proportionally supplies high current based on circuitneeds  or  load  demands—a  common  characteristic  in  wind,  solar,  and  storage  energytechnologies. Its high DC voltage load capability (1,800 VDC) and high ripple current makethis UL810-certified capacitor optimal for high capacitance while minimizing ESR. Similarly, the new C44P-R series is UL-810-certified and features high current capability for input andoutput AC  filtering  (up  to  1,000  VAC)  in  solar  converters,  wind  turbines,  uninterruptiblepower supplies, and power factor correction systems. These cylindrical aluminum canistercapacitors allow for higher energy density, extended life, reliability, and quality constructionsdue to our fully vertically integrated manufacturing facility in Bulgaria.

Designed with a radial box style for PCB mounting, the R75H Pulse series includes thesame high energy density, extended life, and reliability benefits. This series meets one of themost rigorous reliability standards in the industry with its high voltage range (up to 2,000VDC), high capacitance range, high dv/dt capability, and AEC-Q200 certified design. Theseautomotive-grade capacitors can support power conversion for on-board electronics systemsand on-board battery management systems in vehicles, micro-inverters in solar panels, andWBG semiconductor devices in power supply systems. This series is designed for versatilityin harsh conditions due to its THB (Temperature Humidity Bias) test capability of up to 85 ºC/85 R.H and operating temperature up to 125°C. Its high temperature capability is well-suitedfor  applications  that  require  miniaturization  and  fewer  capacitors  due  to  elevatedtemperatures  and  frequencies,  such  as  resonant  tank  circuits  with  WBG  semiconductorcomponents.
