-- RESISTORS
Name:WIRE WOUND RESISTORS
Type:

Description:

KNP type is to wind the resistance wire on a alkaliless ceramic basic, coated with non-corrosive and high insulat-ing heat proof material.

 


  • The resistor is fabricated using a suitable fiberglass or ceramic core with the resistance wire securely crimped to the terminals.
  • Electrical and emchanical stability and high reliability.
  • Tolerance:±1%,±2%,±5%,±10%
