FAQ

 

1. How to choose the resistor ?

   1 We would like to commend the wirewound resistor for you when it will be used in low voltage(220v      -3.5kv). 

   2 It is better to use glass glaze resistor in high voltage(above 5.0kv).

   3 For highfrequency circuits,to recommend oxide film resistor or glass glaze resistors.The resista          nce of the structure.
