Through-hole resistors General Type Wirewound Resistors Normal & Miniature Style [ KNP Series ] FEATURES INTRODUCTION Power Rating 1/4W, 1/2W, 1W, 2W, 3W, 4W, 5W, 7W Resistance Tolerance ±1%, ±5% T.C.R. ±300ppm/°C Flameproof Multi-layer Coating Meets UL-94V-0 Flameproof Feature Meets Overload Test UL-1412 DERATING CURVE The resistor element is a resistive wire which is wound in a single layer on a ceramic rod, with tinned connecting wires of electrolytic copper welded to the end-caps. The ends of the resistive wire are connected to the caps by welding. The resistors are coated with layers of green color flame-proof lacquer. For resistors operated in ambient temperatures above 40°C, power rating must be derated in accordance with the curve below. 40 70 Rated Load (%) 200 275 °C 100 3W-7W 80 1/4W-3WS 60 40 20 50 100 150 200 250 300 Ambient Temperature (°C) DIMENSIONS Unit: mm STYLE Miniature L øD H ød KNP-25 KNP50S 6.3±0.5 2.5±0.3 28±2.0 0.55±0.05 KNP-50 KNP1WS 9.0±0.5 3.5±0.3 26±2.0 0.55±0.05 11.5±1.0 4.6±0.5 35±2.0 0.8±0.05 KNP3WS 15.5±1.0 5.2±0.5 33±2.0 0.8±0.05 KNP5WS 17.5±1.0 6.2±0.5 32±2.0 0.8±0.05 KNP7WS 24.5±1.0 8.2±0.5 38±2.0 0.8±0.05 - 24.5±1.0 8.2±0.5 38±2.0 0.8±0.05 KNP100 ød H L øD KNP200 KNP300 KNP400 KNP500 KNP600 KNP700 Note: KNP1WS ( for MB Type ) ød = 0.8±0.05 mm DIMENSION Normal KNP2WS KNP3SS 43 ELECTRICAL CHARACTERISTICS Normal STYLE STYLE KNP-25 KNP-50 KNP100 KNP200 Power Rating at 40°C Power Rating at 70°C 1/4W 1/2W 1W KNP300 KNP400 KNP500 KNP600 KNP700 3W 4W 5W 6W 7W 2W Maximum working voltage PxR Voltage Proof on Insulation 250V 300V 400V Resistance Range (±1%) 0.1Ω - 150Ω 0.1Ω - 750Ω 0.1Ω - 1.5KΩ 0.1Ω - 2.4KΩ 0.1Ω - 3.3KΩ 0.1Ω - 6.2KΩ Resistance Range (±5%) 0.1Ω - 200Ω 0.1Ω - 800Ω 0.1Ω - 2.2KΩ 0.1Ω - 2.7KΩ 0.1Ω - 3.9KΩ 0.1Ω - 6.8KΩ Operating Temp.
