INTRODUCTION:						DERATING CURVE
(1) The resistor is fabricayed using a suitable fiberglass or
ceramic core with the resistance wire securely crimped
to the terminals.
(2) Small in size comparatively than other kind resistor.
(3) Electrical and nachanical stability and high reliability.
(4) Tolerancs of 5% , 10% are standard.
