Engineering
The CSM’s series of low value current sense resistors
provides power and precision in a four terminal, surface
mount configuration. Its all welded construction is made
up of a Bulk Metal
®
resistive element with plated copper
terminations.
Vishay Foil Resistors’ application engineering department is
available to advise and make recommendations.
