Bourns 91 Series Conductive Plastic Rotary Potentiometer, 10K Linear, 1W

The Bourns 91 Series Rotary Potentiometer (Model 91R1A-R22-B15L) is a high-quality single-turn panel control designed for precision adjustment. Featuring a robust conductive plastic element, it delivers smooth operation and exceptional durability, with a rotational life of 100,000 cycles. This potentiometer is an ideal choice for audio equipment, instrumentation, and industrial control systems where accuracy and reliability are paramount.

Its compact 5/8-inch square design enables space-saving installation, while the 1/4-inch diameter plastic slotted shaft (7/8-inch length) ensures secure knob attachment. The linear taper provides consistent resistance change, making it suitable for fine-tuning applications. With a resistance value of 10 kΩ (±20% tolerance) and a power rating of 0.5W at +70°C, it handles a wide range of signal and control tasks. The component operates reliably across temperatures from –40°C to +125°C.

Engineered for easy panel mounting, this Bourns potentiometer includes PC pin terminals for straightforward soldering. It is RoHS compliant, meeting environmental standards, and is available in a single-gang configuration. The item's compact dimensions (43mm height, 33mm width, 15mm depth) and lightweight design (7.1g) make it a versatile addition to any electronic project.
