Film capacitors roll out for automotive and green energy

Kemet, a subsidiary of Yageo Corp., has released three new series of metallized polypropylene dielectric film capacitors. The C44U-M, C44P-R, and R75H series of film capacitors target green energy, industrial, and automotive applications.

The C44U-M and C44P-R power film series, constructed with an aluminum canister design, address the increasing demand for high-power conversion systems in green energy and industrial applications. They also can be used in power conversion applications in energy storage systems, IGBT, and wide bandgap (WBG) semiconductor devices. The R75H series, a radial box pulse capacitor, also supports these applications, as well as the automotive sector with its high-voltage, AEC-Q200 certified design.

The C44U-M series supports DC networks and proportionally supplies high current based on circuit needs or load demand, which is a common characteristic in wind, solar, and storage energy technologies, said Kemet. The high DC voltage load capability (1,800 VDC) and high ripple current make the UL810-certified capacitor suited for high capacitance while minimizing equivalent series resistance (ESR).

Also UL-810-certified, the C44P-R series features high current capability for input and output AC filtering (up to 1,000 VAC) in solar converters, wind turbines, uninterruptible power supplies, and power factor correction systems.

Designed with a radial box style for PCB mounting, the R75H Pulse series meets one of the most rigorous reliability standards in the industry with its high voltage range (up to 2,000 VDC), high capacitance range, high dv/dt capability, and AEC-Q200 certified design, said Bourns. These automotive-grade capacitors can support power conversion for on-board electronics systems and on-board battery management systems in vehicles, micro-inverters in solar panels, and WBG semiconductor devices in power supply systems.

The R75H series also is suited to harsh environments thanks to its temperature humidity bias (THB) test capability of up to 85ºC/ 85 R.H and operating temperature up to 125°C. The temperature capability is well-suited for applications that require miniaturization and fewer capacitors due to elevated temperatures and frequencies, such as resonant tank circuits with WBG semiconductor components, said Bourns.

The C44U-M, C44P-R, and R75H series are available now through Kemet’s distributors.
