Revision: 09-Jun-08
Manufactured in cermet thick film technology, these power
resistors exhibit remarkable characteristics and the series
includes 4 types ranging from 5 W to 50 W.
Designed to be mounted onto a heatsink, the resistors can
bear high short time overloads and 3 types of terminations
are available.
The resistors are non inductive and are particularly suitable
for high frequency operation and cut-out circuits.
