Bourns 3296 Series Cermet Multi-Turn Trimmer Potentiometer, 500Ω

The Bourns 3296 Series trimming potentiometer is a high-precision, multi-turn component designed for reliable circuit adjustment. Featuring a robust cermet element, it offers exceptional stability across a wide range of applications, making it a trusted choice for calibrating electronic equipment.

With a 25-turn adjustment mechanism, this trimmer provides extremely fine and accurate control over resistance values, allowing for meticulous tuning. Its through-hole mounting ensures a secure and permanent connection on printed circuit boards (PCBs). The design includes a convenient side or top adjustment option via a lead screw, facilitating easy access during calibration.

Key Features & Performance

Engineered for durability, the trimmer boasts a rotational life of 200 cycles and is sealed to an IP65 rating, protecting against dust and low-pressure water jets. This makes it suitable for use in environments where contamination is a concern. It operates reliably across an extensive temperature range from -55°C to +125°C.

The component offers a track resistance of 500Ω with a ±10% tolerance. Its temperature coefficient of ±100ppm/°C ensures minimal resistance drift with temperature changes, guaranteeing consistent performance. With a power rating of 0.5W (500mW), it is capable of handling typical circuit adjustment loads.

Applications

This versatile trimmer is ideal for performing precise adjustments in all types of electronic devices. Typical uses include calibration in production equipment, measuring linear distance, and setting angles or rotations. Its reliable performance makes it essential for prototyping, testing, and final product assembly where exact resistance values are critical.
