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.
