25W 50W 100W 200W 300W 400W 500W 1000W 2000W Adjustable High power
Tube Ceramic Wire Wound power Resistor
We also can make uncommon product per customers requirements.
Features:
1, Resistance range: 0.22~43K ohms
2, Power range:5W~2000W
3, Work Temperature: -55 ~+275 C
4, Resistance tolerance:±5%,±10%.
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.
