CRF High Power Current Sense Resistors

Bourns CRF High Power Current Sense Resistors feature resistance values as low as 0.001Ω and inductance of less than 5nH. The series meets AEC-Q200 and RoHS requirements. These resistors offer low thermal electromotive force (EMF) of <3µV/°C for the 0805 and 1206 package sizes and <40µV/°C for the 2512 size. Bourns CRF Current Sense Resistors operate in a temperature range of -55°C to +170°C. Typical applications include power supplies, stepper motor drives, and input amplifiers.
