CS Series

FEATURES

Easy replacement of vitreous enamel resistors with no cost increase 

and no performance loss.

The whole assembly is coated with multi-layer silicone coating to give 

maximum wire protection form -55°C to +350°C.

Performance improvement is obtained by close tolerance, very low 

temperature coefficient and excellent stability in operation under severe 

environmental conditions.

High level reliability due to ceramic core chemically inert and centerless 

ground for uniformity, selected wire element and completely welded 

construction terminal to terminal.

DERATING

These resistors can be used in a temperature range form -55°C to +350°C

To use these components in applications with working temp. higher  +25°C You have

to make a power reduction with linear derating from nominal power to zero at 350°C

These resistors meet or exceed the requirements of  

MIL-PRF-26 H specifications.
