FUSIBLE RESISTORS. Winsonic 1. INTRODUCTION 2. FEATURES

Transcription

1 INTRODUCTION There are some similarities between Resistors and Fuses in material and structure Fusible Resistors contain both functions, as being resistor in normal condition and changed into fuse while abnormal current comes in protect machines and equipment Since two functions performed by one resistor, the cost therefore saved fusible resistor series are produced with precision technique to get exact fusing time It is also for telephone sets which demand 00V 2 FEATURES z It is suitable for protecting circuit boards z Small in size z Noncombustible insulating coat z Low temperature coefficient z Uniform in fusing time z Body coating is in gray or green, with or color bands or stamping z Too low or too high ohmic value can be supplied only case by case age of
