To meet the growing demand for high-performance electronic components in next-generation automotive applications, Vishay Intertechnology has introduced a new AEC-Q200 qualified, 30W 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 500V operating voltage with a strong overload capability (1.5x Pr for 5s) 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 0.010Ω to 450kΩ, with tolerances down to ± 1%, the device released today serves as the pre-charge or discharge resistor for on-board chargers, battery management systems (BMS), and motor controls for electric vehicles (EV), hybrid electric vehicles (HEV), and plug-in hybrid electric vehicles (PHEV). The RoHS-compliant device offers a non-inductive design and a high dielectric strength of 1500Vrms.
Samples and production quantities of the LTA 30 are available now, with lead times of four to six weeks.
