PTL30-15O0-105B2 is a slide potentiometer with integrated LED from Bourns' PTL Series, designed for professional audio and mixing applications. The device features a 30 mm travel length with a 15 mm lever and orange LED indicator, offering a carbon element construction with linear or audio taper options. It has a 1 megohm resistance value with ±20% tolerance, forward voltage of 2.2–2.5 V for the orange LED, and luminous intensity of 1.5–3.0 mcd at 20 mA. The potentiometer delivers 0.1 watt power rating in linear mode and 0.05 watt in audio mode, with end resistance of 20 ohms maximum. This component is ideal for mixing consoles, drum machines, keyboards, synthesizers, and equalizers where precise audio level control with visual feedback is required.
