Applications UPS Power Through hole 20K ohm of Wirewound resistors

 

Wirewound Fixed Resistors(KNR)

Features:

 

1,Good heat-durability,low temperature coefficient, low noise, high overload power.

 

2, Operating ambient temperature:-55 to +275.

 

3,Surface is nonflammable,the 1/4-6W coating is gray white and indicate the resistance value by color ring, indicate a green ring at the behind of the precision color ring, the 7W or over will indicate the resistance value by lettering and coating is green.

 

4,Resistance tolerance: ±1%, ±2%,±5%,±10%.
