New type RA, stacked polyester capacitors supplies high energy density for high ripple current applications

13 July 2020

New Yorker Electronics will be stocking the new Cornell Dubilier Electronics (CDE) Type RA multilayered polymer capacitors for 125° C operation. Type RA capacitors are constructed using stacked metalized polyester protected with an impregnated sealant, which eliminates the need for an external case. This rugged package style offers the highest energy density technology available for switching power supplies, DC to DC converters and other high ripple current applications.

They are ideal for use in high frequency switching power supplies, noise suppression, electromagnetic interference reduction and long-life applications.

The self-healing capacitors are infused with a microcrystalline polymer sealant and exterior tape wrap that protects the capacitor element from moisture, allowing it to meet 85° C/85% RH requirements for demanding military vehicles and aerospace applications.

Available in capacitance values ranging from 0.1 µF to 10.0 µF, voltage ratings of 100, 250, 400 and 500 V DC, 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.
