PSB shunt from KOA Speer offers better absorption of thermal expansion

Designed with KOA Speer Electronics' original terminal shell, the PSB allows for enhanced absorption of thermal expansion. The PSB current sensing power shunt offers a high power rating of 6W, low resistances of 0.75milli Ohms and 1milli Ohm and a tolerance of 1%.

Due to its special 0.2mm-thick Cu electrode shape, KOA Speer's PSB resistor features excellent temperature cycling characteristics. At the low height of 0.65mm, it is a flat structure with a TCR of ±75ppm, and is applicable for strong mounting as well as automatic mounting machines. The robust PSB features a higher resistance to solder cracking and a smooth current flow ideal for large current detecting.

The PSB is ideal for use in current sensing automotive and industrial applications for ECUs, such as electronic controls, EV and HEV battery management, DC/DC converters, oil and gas down hole equipment, air conditioning/heat pumping, inverter controls, electronic power steering, electric brake systems and water/oil pumps.

Prices start at $3.50 each, and have a lead time of 12 weeks. Samples are available upon request.
