High current metal shunt suited to e-bike power systems

07-01-2025 | Stackpole | Power

As power electronics evolve, the need for high current, low resistance sensing resistors grows. Emerging applications like electric bikes and scooters may need high power, high accuracy, and low thermal resistance. These are a difficult combination for many conventional sense resistor technologies. However, Stackpole Electronic’s HCS series delivers high power, precise sensing and low thermal resistance.

The HCS provides power ratings up to a 10W rated 5930 size with TCR as low as 50ppm and a raised element to improve the thermal footprint of the device and decrease PCB and terminal temperature. Resistance values as low as 0.2 milliohm provide high-efficiency sensing in a surface mountable package. The all-metal construction also supplies a very high pulse withstanding that is superior to that of film or foil on ceramic sense resistor types.
