Vishay 64 Series 20kΩ Multi-Turn Trimmer, 3/8 Inch Square

The Vishay Model 64 is a compact, high-performance multi-turn trimmer potentiometer designed specifically for precision adjustment in electronic circuits. Its small 3/8 inch square footprint (3/8” x 3/8” x 3/16”) makes it ideal for densely populated printed circuit board (PCB) mounting where space is at a premium.

This industrial-grade component delivers excellent operational stability, a key feature achieved through its reliable cermet resistive element. It offers precise control with a generous 23-turn mechanical travel (21 turns electrical), allowing for fine, incremental adjustments to voltage or resistance.

Built for durability in demanding environments, the trimmer is fully sealed to an IP67 rating, making it dust-tight and capable of withstanding temporary immersion in water. It operates reliably across an extensive temperature range from -55°C to +125°C.

The trimmer is available in five different versions to suit various layout requirements, differing by the control screw's position relative to the PCB plane and the spacing of the terminals. This flexibility ensures compatibility with a wide range of circuit designs and assembly processes.

With a resistance value range spanning from 10 Ω to 2.2 MΩ and a robust power rating of 500mW, this versatile component is a trusted choice for calibration, tuning, and set-up applications in professional and industrial electronics.
