14 pplication Note for Power Wire Woun Resistor : - For Silicon Coate Resistors, smoke might be emitte uring initial power loa, this is normal an the resistor is safe. - In case of high frequency application, ha better chose ow-inuctive Resistor. - o not over loa the Resistor to avoi shortening resistor life. - Keeping all other components apart from Resistor, especially temperature sensitive component. - For Resistor nee to work continuously, choose Resistor with rate Power 2 to 4 times higher than the actual loae power can exten resistor life an lower surface temperature. We on't suggest loa resistor up to its 70% rate power for continuous loa work. - For short perio of time overloa the resistor, can withstan 5 times of the Rate Power in 5 secons, however, epens on the current pulse with an resistor series. - Clean Resistor Tab Terminals before use. Cannot clean Resistor with organic solvents. - o not scratch surface of Resistor with any har or pointe object. - o not touch surface of Resistor when it is connecte to a power source ue to the high temperature. - Resistor coating is U 94V-0 class. - Resistor shoul always work within specification. - Resistance, Rate Power, Resistor Size, Mounting Fixture an Inuctive / ow Inuctive can be mae accoring to customer s nee.
