Kemet, newly acquired by Tageo in Taiwan, has launched three series of metallized polypropylene dielectric film capacitors built in Bulgaria for industrial and renewable energy applications.

The C44U-M, C44P-R, and R75H capacitors use an aluminium canister design, with both the C44U-M and C44P-R power film series aimed at high-power conversion systems in renewable 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 pulse capacitor, is similar in that it supports these applications, but also addresses the automotive sector with its high voltage, AEC-Q200 certified design.

The latest C44U-M series features a DC-Link and DC filter power film capacitor for DC networks and supplies high current based on the circuit needs or load demands—a common characteristic in wind, solar, and storage energy technologies. The high DC voltage load capability of 1800 VDC and high ripple current make the UL810-certified capacitor suitable for high capacitance designs while minimizing ESR.

The C44P-R series is also UL-810-certified and features high current capability for input and output AC filtering up to 1000 VAC in solar converters, wind turbines, uninterruptible power supplies, and power factor correction systems. These cylindrical aluminum canister capacitors allow for higher energy density, extended life, reliability, and quality constructions from the fully vertically integrated manufacturing facility in Bulgaria.

The R75H Pulse radial series includes the same high energy density, extended life, and reliability benefits. This series meets one of the most rigorous reliability standards in the industry with its high voltage range up to 2000 VDC, high capacitance range, high dv/dt capability, and AEC-Q200 certified design.

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. This series is designed for versatility in harsh conditions due to its THB (Temperature Humidity Bias) test capability of
