The VPG Foil Resistors FHR 2-3818 is a precision power shunt resistor designed for accurate current measurement and power electronics applications. It uses a low-inductance CuNiMn foil resistive element and an anodized aluminium substrate to support stable resistance performance and effective heat transfer. Its through-hole construction allows heatsink mounting for applications requiring reliable current sensing and precision measurement.
