Miniature sealed multi-turn SMD trimmers for harsh environments

Vishay Intertechnology, Inc. has released a new series of multi-turn, surface-mount cermet trimmers. Developed for space-constrained industrial, consumer, and telecom applications in harsh environments, the TSM3 series devices combine a compact 3mm x 4mm x 4mm footprint with a wide temperature range of -65C to +150C and IP67 sealing.

Compared to previous-generation devices, the trimmers offer a 25% smaller case size and wider operating temperature range. Also, the TSM3 series allows for fine-tuning of its wide 10-Ohm to 2MOhm resistance range and delivers a faster setting-to-time ratio than single-turn trimmers. Offering a 0.125W power rating at +70C, the devices are obtainable in top and side adjustment styles, providing flexibility for various design requirements.

The TSM3 series supports automated PCB assembly and setting processes, enhancing production efficiency to save time and lower costs. Fully sealed to withstand standard board wash processing, the trimmers ensure reliability in automation controls and sensors; welding and cooling systems; robotics; power tools; smoke detectors; radios; and precision testing instrumentation.
