Vishay Model 64 3/8 Inch Square Trimmer Potentiometer, 200Ω

The Vishay Model 64 is a compact, multi-turn trimmer potentiometer engineered for precision adjustment and reliable performance in demanding industrial and electronic applications. Its small 3/8-inch square footprint makes it an ideal solution for printed circuit board (PC board) mounting where space is at a premium.

Excellent operational stability is ensured by the use of a high-quality cermet resistive element. This component is fully sealed to IP67 standards, offering robust protection against dust ingress and temporary immersion in water, which is critical for applications in harsh environments. The trimmer features an industrial-grade 21-turn electrical travel (23 turns mechanical), allowing for fine, precise adjustment of resistance values.

Designed for durability across a wide thermal range, it operates reliably from -55°C to +125°C. The available resistance value range is broad, spanning from 10 Ω to 2.2 MΩ, providing versatility for various circuit tuning needs. This particular model has a track resistance of 200Ω and is configured for top adjustment with through-hole mounting, ensuring a secure and permanent connection on the PCB.

With a power rating of 500mW and a resistance tolerance of ±10%, it delivers consistent and dependable performance. The product is part of the respected 64 Series and meets the stringent MIL-R-22097 qualification, underscoring its suitability for high-reliability military and aerospace specifications where component failure is not an option.
