To address the increasing electrical and thermal demands of hybrid and electric vehicles (EVs), Vishay Intertechnology has introduced an AEC-Q200 qualified, 30-W thick-film power resistor in a compact TO-220 package suitable for direct heatsink mounting.
The Vishay Sfernice LTA 30 is designed for use as a pre-charge or discharge resistor in on-board chargers, battery-management systems (BMS), and motor-control assemblies.
The device supports a wide resistance range from 0.010 Ω to 450 kΩ with tolerances down to ±1 %, enabling flexibility across multiple high-voltage EV subsystems.
For automotive environments, the LTA 30 withstands high humidity, vibration, and temperatures up to +125° C. It provides a 500-V operating voltage and an overload capability of 1.5× rated power for five seconds, supporting stability under transient and high-voltage conditions. T
he resistor features a non-inductive design and a dielectric strength of 1500 Vrms, and is RoHS-compliant.
