The Bourns 3296 Series is a range of high-quality, multi-turn trimming potentiometers designed for precise circuit adjustment in a wide array of electronic equipment. These through-hole mount trimmers utilise a durable cermet resistive element, offering excellent stability and reliability for critical calibration tasks.
Featuring a 25-turn lead screw adjustment mechanism, this model allows for extremely fine and accurate setting of resistance values. This multi-turn capability is ideal for applications requiring high resolution, such as calibrating measurement equipment or fine-tuning analogue circuits. The unit is rated for a rotational life of 200 cycles, ensuring consistent performance over its lifespan.
Constructed in a compact 3/8-inch square form factor, the trimmer is available with side or top adjustment options to suit different PCB layouts and accessibility requirements. It boasts a robust chevron seal design that provides an IP65 environmental rating, protecting the internal element from dust and low-pressure water jets, making it suitable for use in demanding conditions.
This specific model offers a track resistance of 50kΩ with a tolerance of ±10%. It operates reliably across a broad temperature range from -55°C to +125°C, with a low temperature coefficient of ±100ppm/°C. With a power rating of 0.5W (500mW), it is capable of handling typical adjustment circuit demands. The Bourns 3296 Series is a trusted component for engineers requiring dependable and precise variable resistance in prototyping, production, and repair scenarios.
