Shunt resistors with a wide temperature range

Jan 21, 2024

TT Electronics has announced a series of shunt resistors for high current measurements in the hundreds of amps range.

With a temperature range from –65 to +170°C and AEC-Q200 qualification, the EBW5216 series is suitable for industrial and energy management applications, including welding power supplies, motor drives, battery management, energy metering, and process control.

The family is a compact complement to TT's EBW8518 and is busbar-mounted in a 5216 size.

EBW5216 is an electron-beam welded resistance element sandwiched between large copper terminals with optional tin plating. The series offers values of 50 and 100µΩ at down to 1% tolerance, 150ppm/°C TCR (measurement), 20ppm/°C TCR (alloy), and <1µV/°C thermal EMF. The EBW5216's ultra-low ohmic values reduce power loss and its low self-heating reduces equipment temperature and improves reliability.

Equivalent to Vishay WSBS5216, the EBW5216 series offers a robust shunt with the option of pressed pin terminals at voltage sense points, permitting through-hole attachment to a printed circuit board (PCB).

The optional through-hole voltage sense terminations optimise accuracy, allowing complete separation of the current path and voltage sensing.

Featuring a short-term overload rating of 75W for 5s and up to 120J surge capacity, this robust solution is designed to withstand high inrush or switching surges.
