VISHAY Model 64 Trimmer, 24 Turn 5K, Cermet, IP67

The VISHAY Model 64 Trimmer is a compact, multi-turn potentiometer designed to meet the demanding requirements of PC board mounting. Its small footprint (3/8 x 3/8 x 3/16 inch) makes it an ideal choice for space-constrained applications, while its robust construction ensures reliable performance in industrial environments.

Featuring a cermet element, this trimmer delivers excellent operational stability and a low temperature coefficient of ±100 ppm/°C. With 21 turns of electrical travel and 23 turns of mechanical travel, it allows for precise, fine adjustments, and its fully sealed IP67 rating protects against dust and moisture ingress, making it suitable for harsh conditions.

The trimmer operates across a wide temperature range from -55°C to +125°C, and the resistance value range spans from 10 ohms to 2.2 megaohms. This specific model offers a track resistance of 5kΩ with a ±10% tolerance, a power rating of 500mW, and is qualified to MIL-R-22097 standards.
