Bourns CRF2010 series automotive grade current resistor extension

Bourns is pleased to announce the CRF series AEC-Q200 compliant, automotive grade metal strip current sensing resistors with an extended size option of a 2010 footprint. The CRF2010 Series supports resistance tolerances of 1% and 5% with a fixed TCR value of ±50 PPM/°C. These current sense resistors support a resistance range from 1mΩ to 50mΩ. In addition to this, we are also making the CRF2512 available in a high power 3W version supporting a resistance range from 0.3mΩ to 0.75mΩ. This series is suitable for applications requiring a small package size with accurate resistance values, TCRs, and resistance tolerance, such as EV low-voltage distribution current sensing, battery management systems (BMS), inverter phase current monitoring, and robotic drive system current control.
