Metal Oxide Film Resistor
Flame-Proof type  RSU Series ( Standard Size ) 

Click for large

FEATURES :
Low cost with excellent performance
High thermal stability and low surface temperature rise

Small size film resistors are suitable for high density circuit applications.

Flameproof and insulating coating designed to assure safe usage by special non-flammable silicon-base.
Resistor elements have stable characteristics due to thermally and chemically stable materials used.
