Detail
Pre-charge resistors support controlled charging of DC-link capacitors with high pulse energy handling, strong isolation, overload capability and AEC-Q200 compliance, with fully customisable electrical, mechanical and energy characteristics.
Discharge resistors enable rapid, safe capacitor discharge in inverter and EV systems, combining high isolation, vibration resistance and heat-sink mounting with phase change material options for improved thermal performance, all within a compact, lightweight and automotive-qualified design.
