What would happen if you soldered an NTC Inrush Current Limiter to the positive terminal of your cordless drill DC motor, in series with the lead coming from the pulse width modulator (PWM) trigger speed control? Would that make the drill response laggy? Does the resistance change time vary much? What is that attribute called? Thanks.

I have a 75332P MOSFET on a cordless drill controller heatsink. I guess it's part of a pulse width modulator. The drain (flange) connects directly to one of the battery terminals. Does the MOSFET drain go directly to the battery minus/ground terminal? Or does it go to the battery plus terminal? Thanks. -- My application... I'm desperately trying to develop a better inline ...
