WIREWOUND RESISTORS
SILICONE COATED 2 W TO 15 W
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.

Point of measure: L + 20mm
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
