CFN-A Metal Foil Current Sensing Resistors

Bourns CFN-A resistors are metal foil resistors used primarily for current sensing applications. These resistors come in packages ranging from 0402 to 1206, and feature resistance ratings from 5mΩ to 40mΩ. Bourns CFN-A metal foil resistors come in both 5% and 1% tolerances. Applications for these current sensing resistors include power supplies, stepper motor drivers, and input amplifiers.
