YAGEO CORPORATION LEADED RESISTORS Metal Oxide Film Resistors FLAME-PROOF TYPE Normal & Miniature Style [ RSF Series ]
FEATURES
Low Cost, Prompt Delivery High Power-to-Size Ratio for Significant Space Savings Complete Flameproof Construction-UL 1412 High Surge/Overload Capability Non-Inductive Design Wide Resistance Range: 1Ω~1MΩ Resistance T oLerance: ±5% Unit : mm INTRODUCTION These Metal Oxide Resistors offer excellent performance in applications where stability and uniformity of characteristics are desired. They provide lower cost alternatives to Carbon Composition Resistors and General Purpose Metal Films. Metal Oxides also can replace many low power General Purpose wirewound applications, saving both money and time, with shorter delivery cycles. The normal style & the miniature style of RSF series are coated with layers of gray and pink colors flame-proof lacquer respectively. ød H L øD DIMENSIONS STYLE DIMENSION Normal Miniature L øD H ød DERATING CURVE Ambient T emperature (ºC) Rated Load (%) HOT -SPOT TEMPERATURE Surface T emp.
