VISHAY Model 64 Multi-Turn Trimmer 100R Cermet Element

VISHAY Model 64 Multi-Turn Trimmer 100R is a compact multi-turn trimmer potentiometer with a 100 ohm resistance value and a cermet resistive element, designed for precise PCB adjustment.

Overview

The VISHAY Model 64 is designed for precise PCB (Printed Circuit Board) mounting and adjustment. Its small footprint, measuring 3/8 in square and 3/16 in in profile, makes it suitable for densely packed electronic assemblies where space is limited. It provides 21 electrical turns and 23 mechanical turns, allowing very fine, incremental adjustments to resistance. This multi-turn design suits applications that require high precision and repeatability.

Key Features

The trimmer uses a cermet (ceramic-metal) resistive element. It is fully sealed to an IP67 rating, providing protection against dust ingress and allowing temporary immersion in water. With an operating temperature range of -55°C to +125°C, it is intended for use in harsh industrial or outdoor settings. Its top adjustment and through-hole mounting support secure PCB installation. The available resistance range runs from 10 Ω to 2.2 MΩ, and this model is the 100 ohm variant.
