Potentiometer 6.3mm 0.25 Inch Round Shaft Pins 16mm Reverse Audio C RSP63

This is one item of single gang, reverse logarithmic, carbon track potentiometer.

These are new items and come with a nut and a washer for mounting on a front panel. The round shaft is 6.35mm true quarter inch diameter. The mounting hole required is 7mm diameter. The connection pins will allow either PCB mounting or soldered wire connections.

The "C" prefix before the track resistance value denotes a reverse log track taper intended for analogue audio volume controls mounted backwards for some reason or active filter frequency equaliser controls. The max power rating is 0.1W. The track tolerance is 20%. The manufacturer is Alpha Taiwan.

The shaft length on all resistance values of these pots is a total of 15mm, where the threaded part is 6mm long and the turning part is 9mm. I can only get the values already listed in the variations in this exact mechanical size and type.

If you have a pot with a track label of C253, this is an C25K where 3 is the number of zeros after 25 in Ohms. A 502 would be 5K, a 472 would be 4K7 etc. Sometimes pots may also be labelled with the A as a suffix i.e. 25KC.
