Capacitor withstands automotive temperatures

Capacitors announced by Murata Power Solutions are able to withstand the extremely high temperatures experienced by equipment located in severe environments such as the engine compartment of an automobile.

The RHS capacitors have a newly developed heat resistant resin coating around a heat resistant multilayer ceramic capacitor, for use at temperatures up to 200 and as low as -55 degree C.

They comply with AEC-Q200 and the lead wires can be soldered or crimped to position them close to a noise-generating source. They also pass the extreme surge test of the ISO7637-2 standard.

Capacitance values from 100pF to 0.01microF will be available, and the line-up initially includes 200 and 500V DC rated products. At temperatures above 150 degree C, voltage derating is applied. For example, a 500V rated capacitor is rated at 125V when used at 200 degree C. 

Determined by the combination of rated voltage and capacitance value, the capacitors measure 4.0 x 3.5 or 5.5 x 4.0mm, with lead centres being 2.5 or 5.0mm as appropriate.

Full production begins in May 2017.
