The Milliohm Electronics HoLRS Series represents the next generation of unencapsulated bare metal alloy current sensing resistors. Engineered specifically for demanding power conversion and battery management systems, the HoLRS series features resistance ratings from ultra-low 0.033 mΩ up to 6 mΩ and power ratings up to 15W in compact SMT package footprints ranging from 1206 to 7034. By eliminating outer plastic molding, the HoLRS series achieves exceptional direct thermal convection, minimum board space occupation, and high impulse energy capability. Constructed with advanced resistive alloys including Karma, Manganin, and FeCrAl, this series delivers TCR performance down to ±10 ppm/°C and parasitic inductance under 3 nH.
