Potentiometer prefix - A, B, C?
« on: December 04, 2021, 01:36:11 am »
I'm looking for some potentiometers and I noticed that the various values are prefixed by A, B or C. Is there any significance to these letters or do I only concern myself with the resistor's value?

It signifies the "taper" -- the relationship between how much the pot is rotated and the resistance at the wiper.

Thanks! Taper was the keyword I needed to search for.

Log, linear, and antilog taper.
