High Voltage Thick Film Chip Resistor for Automotive Applications

February 14, 2020 by Paul Shepard

KOA Speer Electronics has introduced the HV73V high voltage flat chip resistor designed specifically for automotive applications. The HV73V features a special inner electrode material that makes the resistor suitable for high voltages.

Automotive applications for KOA's HV73V include battery modules, inverter circuits, ac-dc converters, voltage detection circuits of quick chargers and various circuits where regenerative voltage of a motor is applied.

The HV73V achieves maximum working voltages 2.5-times higher with improved temperature cycling stability compared to standard resistors. The HV73V is available in the following chip sizes and voltages: 0603 rated for 350Vac; 0805 rated for 400Vac; and 1206 rated for 800Vac.

KOA Speer's HV73V offers resistance tolerances of +0.5%, +1%, +2%, and +5%, a resistance range of 10kΩ to 51MΩ, T.C.R. values of +100ppm/°C and +200ppm/°C, and operating temperatures up to +155°C. The HV73V is AEC-Q200 qualified.

Lead time is eight weeks. Contact KOA Speer Electronics for samples or additional information.
