The document describes open frame PCB mounting radial type current sense resistors. It summarizes key details about the resistors in 3 sentences: The HEW series current sense resistors feature edge welding for reduced PCB footprint, negligible inductance, and resistance values from 25 milliohms to 10 ohms with power ratings from 1W to 5W. They have very low TCR, meet various qualification tests, and provide high surge current capability due to their unique construction. The resistors isolate the temperature of the resistance band from the PCB to prevent overheating while dissipating heat to the air.
