Shunt resistors suit sensing currents up to 45A

The resistors are in stock at distributor Charcroft Electronics.

The resistors are designed in inverse format with terminations on the long sides, which gives good resistance to thermal and board flex stresses and supports the use of wide current traces.

With a precision of down to 1% tolerance and 170ppm/°C, ULR2N offers a choice of 5 ohmic values from 1 to 3mΩ.

Rated at 2W, this product is suitable for sensing currents at levels up to 45A, and is therefore in many cases restricted only by the current carrying capacity of the PCB traces.

The bulk metal technology used for these parts gives high energy capacity for current surge events, compared to film or foil alternative technologies.

Applications include power supplies, motor control, actuator control and DC-DC convertors in the automotive, industrial and medical market segments.

AEC-Q200 is pending.
