Vishay Intertechnology recently released a new series of industrial-grade, multi-turn, surface-mount cermet trimmers, the Vishay Sfernice TSM41 series devices. These trimmers are engineered for space-constrained applications in harsh environments, combining a compact 4mm x 4mm.
Compared with previous-generation devices from Vishay, the trimmers released today offer a 42% smaller case size, enabling designers to save board space and optimise package density. Additionally, 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 0.25W 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.
