Application Notes

Determination of End Resistance Value of FVR, DQS, DSRA, DSRB, BSR, BSQ:

● Resistance Range means you can choose one maximum resistance value (End resistance value)

at one of FVR, DQS, DSRA, DSRB, BSR, BSQ VR (Variable Resistor) type.

● After End Resistance Value confirmed, the minimum resistance (start resistance value) will be

determined by depending on resistance of wire and wirewound type.

Product type means one of FVR, DQS, DSRA, DSRB, BSR, BSQ.

Rated Wattage means power rating at End Resistance Value.

Resistance Value (Ω) means maximum resistance value (End Resistance Value).

Resistance Tolerance means precision range of End Resistance Value.

1. Power Rating of VR (Variable Resistor) is determined by the maximum resistance value

(End Resistance Value).

2. Resistance and Power Rating should be decreased while you are adjusting the screw.
