Metal Oxide Film Resistor
Flame-Proof type RHS, RUS Series ( Miniaturized )

FEATURES : 

Low cost with excellent performance
Valuable board space is greatly increased.
Increased terminal strength in comparison axial leaded resistors.
High thermal stability and low surface temperature rise
Small size film resistors are suitable for high density circuit applications
The surface area of the terminals has been increased to enhance their heat dissipating capacity.
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
Film material¡G0.1£[¡ã9.1£[ Ni-P, other SnO2
