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 high-frequency circuits,to recommend oxide film resistor or glass glaze resistors.The resistance of the structure body,determines that it has a low inductance.There are requirements on the circuit inductance,film resistor is your best choice.
