Bourns 3386 Series 100Ω Single Turn Cermet Trimmer Potentiometer

The Bourns 3386 Series is a high-quality range of cermet trimming potentiometers designed for precise circuit adjustment. These compact, 3/8-inch square, through-hole devices are essential for calibrating and tuning electronic circuits in a wide array of equipment. As single-turn trimmers, they offer a straightforward and reliable method for making a variety of resistance adjustments with excellent stability.

Constructed with a durable cermet element, these trimmers provide a robust performance with a resistance tolerance of ±10% and a low temperature coefficient of ±100ppm/°C. This ensures consistent operation across a broad temperature range from -55°C to +125°C, making them suitable for demanding environments. With a power rating of 0.5W and a rotational life of 200 cycles, they are built for reliable, long-term use in prototype, development, and production applications.
