Overview
The SAE CD3-1A power line EMI filter is a general-purpose electromagnetic interference suppression device rated for 3A continuous current at 250V AC operation. SAE Power EMI filters are engineered to suppress undesirable electrical impulses and disturbances in power lines, allowing equipment to operate reliably on a common power source. The CD3-1A utilizes series inductance and shunt capacitive elements to create impedance mismatch at high frequencies, effectively attenuating conducted noise.
