PTL20-15R0-103B1 is a slide potentiometer with integrated LED from Bourns' PTL Series, designed for professional audio and electronic control applications. This model features a 20 mm travel length with a 15 mm lever, 10 kO resistance value with ±20% tolerance, and a red LED indicator for visual feedback. The potentiometer incorporates a carbon element with linear taper characteristics, center detent option, and operates with a maximum end resistance of 10 ohms and power rating of 0.05 watts. It provides 100 megohms minimum insulation resistance at 250 VDC and withstands 300 VAC dielectric voltage, ensuring reliable performance in demanding environments. The red LED operates at a forward voltage of 1.8–2.0 V with a luminous intensity of 12–20 mcd at 20 mA, offering clear visual indication. This component is ideal for mixing consoles, drum machines, keyboards, synthesizers, and equalizers where compact slide control with integrated status indication is required.
