NEW BEDFORD, Mass.– Cornell Dubilier Electronics (CDE) announced the availability of its Type RA multilayered film capacitors for operation at 125°C.
The Type RA capacitors are constructed using stacked metallized polyester, protected with an impregnated sealant that eliminates the need for an external case, the company said in a press release. This package style is said to offer “the highest energy density technology available for switching power supplies, DC-to-DC converters, and other high ripple current applications.”
Type RA capacitors are impregnated with a microcrystalline polymer sealant and exterior tape wrap that protects the capacitor element from moisture, allowing it to operate at 85 °C and 85 percent RH in demanding applications in military vehicles and aerospace, the company said.
Available in capacitance values ranging from 0.1 μF to 10.0 μF, voltage ratings of 100, 250, 400, and 500 Vdc, Type RA capacitors are terminated with radial leads to cover a broad range of applications in power electronics where high-density capacitors are needed for board-level DC filtering.
Cornell Dubilier (www.cde.com) said that it has been dedicated to advancing capacitor technology for new applications since its founding in 1909. The company leverages its engineering capabilities to provide components for inverters, wind and solar power, electric vehicles, power supplies, motor drives, HVAC, motors, welding, aerospace, telecom, medical equipment, and UPS systems. A global company, Cornell Dubilier has ISO-9001 certified manufacturing and distribution facilities in Liberty, South Carolina; New Bedford, Massachusetts; Mexicali, Mexico; and Hong Kong.
