variable Glaze high power ceramic resistor 

Coated High Power Ceramic Tube Resistors (HPR)

1,Surface glazed, won't be easily polluted or eroded by chemistry gas, hi8gh insulating capacity, can resist himidity and heat well, can be use in the atrocious environment.

2,Good overload and heat durability capacity, the useful time is longer than the others.

3,Resistance tolerance:±5%, ±10%
