24mm (diameter) Audio Taper Potentiometers. Available in various resistances from 1K through one megohm (at) 0.5 watt. Rating for the the 500K and 1 Meg is 0.25 watt. voltage: 250V DC (Mounting nut and washer are included.) Rotational stop shaft with flat for knob with set screw or spring. Tolerance 20%.

Note: COMBO terminals are made to be used easily as PC board mounting or solder type.

16mm AUDIO Taper potentiometers.

Rated wattage: 0.1 watt. Rated voltage: 200V DC (Mounting nut and washer are included.) Rotational stop shaft with flat for knob with set screw or spring. All of the potentiometers in the following chart have "Combo" terminals except for number PC825 which has solder lug style terminals and will not fit into a PC board.

Tolerance at rated resistance is 20%; maximum voltage for the linear types is 150V AC and for the Audio tapers is 200V AC. Power rating for linear units is 200mA and for Audio Taper units is 100mA. Switch rating is universally 1.0Amps at 12V DC or 125V AC. Total rotation is 300 degrees. Rotation life cycles is 15,000 cycles. Busing diameter 7mm, Shaft length is 30mm and 12mm with flat.
