Vishay Model 64 Trimmer, 24 Turn 100R, Cermet Element

The Vishay Model 64 is a compact, multi-turn trimmer potentiometer designed for precise PCB (Printed Circuit Board) mounting and adjustment. Its small size – measuring 3/8” square and 3/16” in profile – makes it ideal for densely packed electronic assemblies where space is at a premium. This industrial-grade component provides excellent long-term operational stability, a critical feature for calibration and tuning applications in demanding environments.

The trimmer utilises a high-quality cermet (ceramic-metal) resistive element, ensuring reliable performance and durability. It is fully sealed to an IP67 rating, providing complete protection against dust ingress and allowing it to withstand temporary immersion in water. This makes it suitable for use in harsh industrial or outdoor settings. The component offers a broad operating temperature range from -55°C to +125°C, guaranteeing functionality in extreme conditions.

With an electrical travel of 21 turns and a mechanical travel of 23 turns, it allows for very fine, incremental adjustments to resistance. This multi-turn design is perfect for applications requiring high precision and repeatability. The available resistance value range is extensive, from 10 Ω up to 2.2 MΩ, providing great versatility for different circuit designs. This specific model is a 100-ohm variant, featuring top adjustment and through-hole mounting for secure PCB installation.
