可调电阻的额定功率:
FVR, DQS, DSRA, DSRB, BSR, BSQ 料号说明:
型号
- 额定功率 (W)
- 最大可调阻值 (Ω)
- 阻值公差
型号是指 FVR,DQS,DSRA,DSRB,BSR,BSQ。
额定功率是指调到到最终阻值(最大可调阻值)时,可持续应用到线绕电阻本身的最大功率。
最大可调阻值 (Ω) 是指线绕电阻最大可用的电阻值。
阻值公差是指线绕电阻在最大可调阻值时与标称值的偏差值,通常以百分比表示。
1. 可调电阻的额定功率是由最大可调阻值与额定电压抉定。
2. 当你调节可调电阻,从最终阻值(最大可调阻值)到起始阻值(最小可调阻值)时,电阻值将随功率递减而递减。
注意:
