Wire-wound resistors in ceramic tube (KFD)

Construction and execution

As carrier for the resistance wire, a fibreglass cord is used. The wire-winding is safely joined to the tinned copper connection wires with pressed-on caps. The resistors are inserted into a ceramic tube with square cross section.

Features

  • Nominal power range: 4 W up to 30 W
  • Protection against atmospheric influences
  • Housing provides superior heat conduction
  • High dielectric strength

Application fields

For an application in a harsh environment and the direct mounting on metal chassis.
