Bourns has expanded its CSS2H-5930 and CSI2H-5930 current sense resistor series with eight new 0.1 mΩ models for high-current power systems.
The new resistors are rated at 15 W and use an electron-beam-welded metal strip design. Their ultra-low resistance is intended to reduce voltage drop and power loss while maintaining accurate current measurement.
For electric vehicle (EV) applications, the automotive-grade CSS2H-5930R-L100x is AEC-Q200 compliant and suited to high-current battery and power-conversion systems.
Low inductance helps improve measurement performance in circuits with rapidly changing current, while low thermal electromotive force (EMF) helps reduce temperature-related measurement error.
The 0.1 mΩ resistance value is intended for applications where current sensing must introduce as little additional loss as possible. This can be important in EV battery and power-electronics systems, where sensing accuracy and thermal performance directly affect system design.
The new models are supplied in a compact surface-mount package and extend the existing CSS2H-5930 and CSI2H-5930 product families
