INTRODUCTION
• The resistor is fabricated using a suitable
fiberglass or ceramic core with the
resistance wire securely crimped to the
terminals
• Small in size comparatively than other kind
resistor
• Electrical and Mectanical stability and high
reliability
• The KNP/NKN series are coated with
layers of green color flame-proof lacquer.
The resistors meet overload tests in
accordance with UL specification #1412
without producing a fire hazard
