Power Resistors, for Mounting onto a Heatsink
Thick Film Technology
FEATURES
• 5 W to 50 W
• High power rating
• High overload capabilities up to 2500 VRMS
• Wide resistance range from 0R24 to 1 MΩ
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.
• High thermal capacity up to 0.8 °C/W
• Easy mounting
• Reduced size and weight
• High insulation: 106 MΩ
