MELF Fusible Resistor-MEFRN

There are some similarities between Resistor and Fuses in material and structure. Fusible Resistor contain both functions, as being Resistor in normal condition and changed into fuse while abnormal Current comes in to protect machine and equipment. Since two functions performed by one resistor, the cost therefore saved. FR Fusible Resistor series are produced with precision technique, Enabling precise fusing time and stabilized, aiming to reach best Quality Resistor.
