BOURNS PTV09A Series 10K Carbon Rotary Potentiometer, 1-Turn Linear, 50mW, 9mm

The BOURNS PTV09A Series Rotary Potentiometer is a compact 9mm carbon element control, ideal for a wide range of audio and commercial applications. This through-hole, single-gang potentiometer features a 10K ohm resistance with a ±20% tolerance, ensuring consistent and reliable performance in demanding signal and control circuits.

Designed for horizontal/rear mounting (bushingless) and equipped with a flatted, insulated shaft of 25mm, it offers a straightforward installation for space-constrained enclosures. The linear track taper provides predictable, uniform response across its rotation, while the centre detent offers tactile feedback for positioning and menu navigation.

With a robust carbon resistive element, this potentiometer delivers a 0.05W power rating and operates reliably across a temperature range of -10°C to +50°C, making it suitable for commercial communication gear, portable electronics, and consumer appliances.
