Vishay Intertechnology unveiled a new AEC-Q200 qualified LTA 30 W thick film power resistor in a compact TO-220 package for direct mounting on a heatsink in response to the increasing need for high performance electronic components in next-generation automotive applications.
The Vishay Sfernice LTA 30 is designed to provide outstanding reliability and durability in even the most harsh automotive environments. It can tolerate temperatures as high as +125 °C and high humidity levels while offering a high tolerance against vibration and electrical stress.
To guarantee stability during transients and high voltage situations, the resistor also combines a high 500 V operating voltage with a robust overload capability (1.5x Pr for 5 s). When combined, these qualities ensure reliable performance in applications where safety is crucial.
The newly released device functions 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).
It offers a wide range of resistance values from 0.010 W to 450 kW with tolerances down to ± 1%. The RoHS-compliant device has a high dielectric strength of 1500 Vrms and a non-inductive construction.
Availability
Samples and production quantities of the Vishay Sfernice LTA 30 are available now, with lead times of four to six weeks.
