Vishay Intertechnology has introduced four thick film resistor sample kits designed to simplify component selection and validation for high-power designs while shortening time to market. Announced from Malvern, Pennsylvania, on September 24, 2026, the kits are evaluation-ready, and each one includes surface-mount, Automotive Grade devices in TO-252 (DPAK) and TO-263 (D2PAK) packages, with high power ratings, a wide range of resistance values, and an optional PCB test board for fast, reliable electrical and thermal evaluation.
The four kits are the Vishay Sfernice D2TO20, D2TO35, DTO35, and DTO35 / D2TO35 sample kits. Their devices offer power ratings of 20 W and 35 W in compact surface-mount packages, and this high power density lets designers reduce the number of parallel resistors or larger through-hole devices they need, saving board space. The kits suit automotive, industrial, and other high-reliability designs, and all resistors in them are AEC-Q200 qualified, which removes the need for additional component qualification during development.
The kits cover resistance values from 1 Ω to 47 kΩ using selected E-series values, which cuts down sampling effort and reduces the need for extra sample orders compared with typical single-value or single-package kits. The devices are supplied on cardboard tape strips holding four resistors each, sorted in ascending order of resistance and clearly labeled for easy identification. Together with the optional PCB test boards, this organization shortens lab setup time and speeds up design-in.
The resistors use a non-inductive construction and provide electrical isolation between the resistor element and the metal tab, ensuring stable high-frequency performance and enhanced safety. They are compatible with standard surface-mount assembly processes, including proven reflow resistance up to 270 °C for 10 seconds, which improves assembly margin and manufacturing yield.
