Product Name : WIRE WOUND RESISTORS FLAME-PROOF COATING RW (KNP) TYPE
Description
INTRODUCTION:
RW (KNP) type is to wind the resistance wire on a alkaliless ceramic basic, coated with non-corrosive and high insulating heat proof material.
FEATURES:
- Super heat dissipation.
- Small linear temperature coefficient.
- Instant overload capability.
- Low noise figure and without annual shift on resistance value.
