PSB Power Shunt from KOA Speer allows for Enhanced Absorption of Thermal Expansion

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.
