    I have a three phase motor controller which has two thermistors SL22 1R020, located at the positive and negative leg of a bridge rectifier respectively. Then, it feeds a bank of capacitors. I can try uploading an schematic if needed for this. One of the thermistors is burnt. I don't have the same replacement. However, I have this one SL32 2R025. Do you think it works? I haven't made a deep analysis on why the designer selected that thermistor value.

    One is 1 ohm 20Amp, the other 2 ohms 25Amps, probably best to replace both for the same 2/25 types.
