Vishay Intertechnology, Inc. has launched a new series of industrial-grade, multi-turn, surface-mount cermet trimmers. The Vishay Sfernice TSM41 series of sealed trimmers with IP67 sealing are designed for space-constrained applications in harsh environments.
The cermet trimmers, housed in a 4 × 4-mm footprint, operate over a wide temperature range of -55°C to 140°C. Compared to previous-generation devices, these trimmers offer a 42% smaller case size.

The TSM41 series offers fine-tuning of its wide 10-Ω to 1-MΩ resistance range, and a faster setting-to-time ratio than single-turn trimmers. Other features include a 0.25-W power rating at 85°C, and top and side adjustment styles for design flexibility.
The TSM41 series can be mounted directly to the printed circuit board (PCB), allowing for automated PCB assembly and setting processes, while enabling the components to be placed on both sides of the board, Vishay said. They are fully sealed to withstand standard board wash processing, and can be used in welding equipment, power tools, and smoke detectors, as well as heating, cooling, and ventilation systems.
Samples and production quantities of the TSM41 series are available now. Lead time is 15 weeks.
