Low Current Applications

Very low current applications have unique requirements that can exceed the capabilities of standard potentiometers. However, recent advances in design and materials now make it possible to apply Bourns precision potentiometers in many such applications. Also, certain Bourns models are being used successfully as high-resolution trimmers, another technically demanding application.
