Cornell Dubilier recently rolled out its Type CS multi-layered polymer capacitors for 125C applications with 6/6 RoHS compliance. Terminated with multiple pin connections, the Type CS capacitors have low equivalent series resistance, and are designed for switching power supplies, DC to DC converters and other high ripple current applications.

"Large ceramic capacitors are prone to cracking and have other performance drawbacks. Type CS caps are made using stacked polyester, which offers many advantages over ceramic capacitors including, but not limited to, capacitance and dissipation factor stability with temperature, self-healing, no piezoelectric effect and they're more resistant to thermal shock," said Mike Rapoza, Cornell's product manager.

Available in capacitance values ranging from 2.0?F to 10.0?F, voltage ratings of 50, 100, 250, 400 and 500VDC, and current ratings up to 18A rms, Type CS capacitors cover a broad range of applications in power electronics where high capacitance and high current are needed for DC filtering.

Type CS capacitors have multiple pin leads, up to 18 on the larger sizes, and UL94V-O rated epoxy exterior with the ability to pass 85C/ 85 per cent RH requirements for demanding applications in military vehicles and aerospace.
