To meet the growing demand for high performance electronic components in next-generation automotive applications, Vishay Intertechnology, Inc. introduced a new AEC-Q200 qualified, 50 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 50 resistor withstands high humidity conditions and temperatures to +175 °C, while providing a high tolerance against vibration and electrical stress.
This guarantees 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, with a high dielectric strength of 1500 Vrms and limiting element voltage of 500 V.
Samples and production quantities of the LTA 50 thick film resistors are available now, with lead times of 10 weeks.
FEATURES
- 50 W at 50 °C case temperature heatsink mounted
