Bourns 3296 Series Cermet Multi-Turn Trimmer Potentiometer 500Ω

Bourns 3296 Series Cermet Multi-Turn Trimmer Potentiometer 500Ω is a multi-turn trimmer with a 500Ω track resistance, built for accurate circuit adjustment on printed circuit boards (PCBs).

Overview

The Bourns 3296 Series is a high-precision, multi-turn trimming potentiometer designed for reliable circuit adjustment. It features a cermet element and a 25-turn adjustment mechanism, which allows fine control over resistance values and supports meticulous tuning. The through-hole mounting provides a secure, permanent connection on printed circuit boards, and the top or side adjustment option via a lead screw makes the adjustment point easy to access during calibration.

Key Features

• Cermet element for stable resistance performance
• 25-turn adjustment mechanism for fine control
• Through-hole mounting for PCB installation
• Top or side adjustment via lead screw
• Sealed to an IP65 rating, protecting against dust and low-pressure water jets
• Rotational life of 200 cycles
• Operating temperature range from -55°C to +125°C
• Track resistance of 500Ω with ±10% tolerance
• Temperature coefficient of ±100ppm/°C
• Power rating of 0.5W (500mW)

Applications

This trimmer is suited to precise adjustments in electronic devices. Typical uses include calibration in production equipment, measuring linear distance, and setting angles or rotations. It is also suitable for prototyping, testing, and final product assembly where exact resistance values are important. The sealed construction makes it suitable for environments where dust or contamination is a concern.

Summary

The Bourns 3296 Series Cermet Multi-Turn Trimmer Potentiometer 500Ω combines a stable cermet element with fine 25-turn adjustment and through-hole mounting, making it a practical option for PCB-based circuit tuning and calibration.
