Through-hole resistors Metal Glazed Film Resistors High Voltage & High Ohmic Type Normal & Miniature Style [ HHV Series ] FEATURES Power Rating 1/4W, 1/2W, 1W, 2W, 3W Resistance Tolerance ±1%, ±5% T.C.R. ±200ppm/°C Flameproof Multi-layer Coating Meets UL-94V-0 Flameproof Feature Meets Overload Test UL-1412 INTRODUCTION DERATING CURVE The HHV Series High Voltage & High Ohmic Resistors are made of metal glaze film, with tinned connecting leads of electrolytic copper welded to the end-caps. The resistors are coated with layers of pink color lacquer. For resistors operated in ambient temperatures above 70°C, power rating must be derated in accordance with the curve below.
