BOURNS 3296 Series Cermet Multi-Turn Trimming Potentiometer, 100Ω, 25 Turn, 3/8

The BOURNS 3296 Series are high-quality, multi-turn trimming potentiometers built with a robust cermet element. Designed for through-hole mounting, these components perform a wide variety of precision circuit adjustments in all types of electronic equipment, offering exceptional control and stability.

Featuring a 3/8-inch square form factor with top adjustment via a lead screw, these trimmers are engineered for reliable and precise calibration. They are sealed to an IP65 rating, providing effective protection against dust and water jets, which makes them suitable for use in more demanding environments.

A key specification is the 25-turn mechanism, which allows for very fine resolution when setting the resistance value. This is complemented by a rotational life of 200 cycles, ensuring long-term durability and consistent performance. The resistance value for this specific model is 100 ohms (Ω), with a tolerance of ±10%. The temperature coefficient is ±100ppm/°C, contributing to stable operation across a broad temperature range.

Typical Applications

These trimming potentiometers are commonly used for precise adjustments in measurement and control circuits. Typical applications include measuring linear distance, angle, or rotation in production equipment, as well as general calibration and tuning within amplifiers, power supplies, and signal conditioning modules.
