CEMENT TYPE RESISTORS (LRW ; CM)
 
 
Features
 
  • Has a non-flammable material that will not ignite during overload.

  • Complete insulation makes it suitable for P.C. board mounting.

  • Precise resistance value with high stability.

  • Super heat dissipation, small linear temperature coefficient.

  • Low noise.

  • For high resistance value, the winding core is replaced by Metal Oxide Film cutting core.
