Type RA capacitors are constructed using stacked metallized polyester protected with an impregnated sealant, which eliminates the need for an external case.
Cornell Dubilier announces availability of its Type RA multilayered film capacitors for 125°C operation. Type RA capacitors are constructed using stacked metallized polyester protected with an impregnated sealant, which eliminates the need for an external case. This package style offers 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 meet 85 °C/ 85% RH requirements for demanding applications in military vehicles and aerospace.
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 RA capacitors series are available through our key franchised distributor sites for quick turnaround on prototype and pre production quantities.
