Pickup pot wattage?

[Greg_M]

I want to add a pickup and it's volume and tone controls. The routed out area will be a little snug so I am considering mini pots. But they seem to be of lower wattage rating than the regular size pots. The minis are 0.1 w.

In a passive system will the lower wattage rating be a problem?

Thanks

It doesn't matter. You're talking a few Volts at millionths of an Ampere. Just about any pot can handle the thermal dissipation.

To put it another way P=V*V/R or V=sqrt(P*R). Using the second form of the equation, your power rating of 0.1 W and 250000 Ohms pot resistance your pickup voltage would have to be about 158 Vrms to push the pot to its power limit. I think you will be quite safe with 0.1W pots....

The mini pots are fine.
