Vishay Intertechnology Introduces Miniature, Sealed, Industrial-Grade Multi-Turn SMD Cermet Trimmers for Harsh Environments

Rhea-AI Summary

Vishay Intertechnology (NYSE:VSH) has unveiled its new TSM41 series of industrial-grade, multi-turn, surface-mount cermet trimmers. These innovative devices feature a compact 4mm x 4mm footprint, representing a 42% size reduction from previous generations.

The trimmers operate across a temperature range of -55°C to +140°C with IP67 sealing, offering resistance ranges from 10Ω to 1MΩ and a power rating of 0.25W at +85°C. Available in both top and side adjustment styles, they are designed for PCB mounting and automated assembly, making them ideal for welding equipment, power tools, smoke detectors, and HVAC systems.

Samples and production quantities are currently available with 15-week lead times.

Positive

• 42% smaller case size compared to previous generation, optimizing board space
• IP67 sealing and wide temperature range (-55°C to +140°C) for harsh environments
• Supports automated PCB assembly and setting processes, improving production efficiency
• Versatile resistance range (10Ω to 1MΩ) with both top and side adjustment options

Negative

• 15-week lead time for production quantities may impact supply chain planning

Offered in Compact 4 mm x 4 mm Footprint, Space-Saving Devices Feature IP67 Sealing and High Temperature Operation to +140 °C

MALVERN, Pa., Aug. 13, 2025 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of industrial-grade, multi-turn, surface-mount cermet trimmers. Designed for space-constrained applications in harsh environments, the Vishay Sfernice TSM41 series devices combine a compact 4 mm by 4 mm footprint with a wide temperature range of -55 °C to +140 °C and IP67 sealing.

Compared to previous-generation devices, the trimmers released today offer a 42 % smaller case size, allowing designers to save board space and optimize package density. In addition, the TSM41 series allows for fine-tuning of its wide 10 Ω to 1 MΩ resistance range, and a faster setting-to-time ratio than single-turn trimmers. Offering a 0.25 W power rating at +85 °C, the devices are available in both top and side adjustment styles, providing flexibility for various design requirements.

The TSM41 series can be mounted directly to the PCB, allowing for automated PCB assembly and setting processes — enhancing production efficiency to save time and lower costs — while enabling the components to be placed on both sides of the board. Fully sealed to withstand standard board wash processing, the trimmers ensure reliability in welding equipment, power tools, smoke detectors, and heating, cooling, and ventilation systems.

Samples and production quantities of the TSM41 series are available now, with lead times of 15 weeks.
