Bourns CRK1225 series automotive grade current resistor extension

The Bourns is pleased to announce the extension of its CRK series. The new CRK1225 series provides a higher power rating of up to 3W and supports a wider resistance range.

Current sense resistors are growing in popularity due to their small package size, accurate TCR and relatively low cost compared to other technologies. These resistors detect and convert current to an easily measured voltage which is proportional to the current flowing conducted through the device.

The CRK series can be measured as 4-terminal resistors. A recommended layout guide is provided in the Bourns datasheet to allow customers to easily design their PCB and measure current flow.
