Model CSM2F Series High-Power Current Sense Resist

Model CSM2F Series High-Power Current Sense Resist

Bourns model CSM2F series current sense resistor family includes CSM2F-8518, CSM2F-7036, and CSM2F-6918 models. This Bourns' range of high powered current sense resistors is manufactured using metal alloy element electron beam welded to tinned copper terminals.

The Bourns Model CSM2F series comes in three different footprint sizes: 8518, 7036, and 6918 metric, with resistance values as low as 50 μΩ, continuous current up to 1000 A, and permanent power ratings of up to 50 W. The new Model CSM2F series is AEC-Q200 compliant with a high pulse power rating.

Their metal alloy current sensing element allows thermal EMF as low as 0.25 μV/K and low TCRs of 50 PPM/°C in the +20°C to +60°C temperature range.

Current sense resistors are growing in popularity due to their high measurement accuracy 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 through the device.

This product series complements Bourns' other circuit conditioning components, such as power inductors and rectifier diodes.
