500W High Power Wattage Adjustable Sliding Ceramic Tube Wire Wound Power Resistor
We also can make uncommon product per customers requirements.
Features:
1, Resistance range: 0.33 ohm ~33K ohm
2, Power : 500W
3, Work Temperature: -55 ~+275 C
4, Resistance tolerance: 5%, 10%.
5, Good heat-durability,low temperature coefficient,and high capacity of short time overload
6, The resistor’s surface coats green incombustible paint.
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.
Good overload and heat durability capacity, the useful time is longer than the others.
