Vishay Sfernice
Power Resistor, for Mounting onto a Heatsink
Thick Film Technology
FEATURES
? 5 W to 50 W
? High power rating
? High overload capabilities up to 2500 V RMS
? Wide resistance range from 0.24 M ? to 1 M ?
? High thermal capacity up to 0.8 °C/W
? Easy mounting
? Reduced size and weight
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.
