MALVERN, Pa. — Nov. 19, 2025 — To meet the growing demand for high performance electronic components in next-generation automotive applications, Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new AEC-Q200 qualified, 30 W thick film power resistor in a compact TO-220 package for direct mounting on a heatsink.

Engineered to ensure exceptional reliability and durability in even the most extreme automotive environments, the Vishay Sfernice LTA 30 withstands high humidity conditions and temperatures to +125 °C, while providing a high tolerance against vibration and electrical stress. In addition, the resistor combines a high 500 V operating voltage with a strong overload capability (1.5x Pr for 5 s) to ensure stability under transients and high voltage conditions. Together, these characteristics guarantee consistent performance in safety-critical applications.

Offering a broad range of resistance values from 0.010 W to 450 kW, with tolerances down to ± 1 %, the device released today serves as the precharge or discharge resistor for on-board chargers, battery management systems (BMS), and motor controls for electric vehicles (EV), hybrid electric vehicles (HEV), and plugged hybrid electric vehicles (PHEV). The RoHS-compliant device offers a non-inductive design and a high dielectric strength of 1500 Vrms.
