Ultra High Current Ferrite Common Mode Chokes for AC and DC Power Supplies • Up to 55 Amps Contiuous Operating Current • Effective for Low and High Frequency Applications US Patent: 5,568,111 Features: •Designed to be UL 1950 compliant for creepage up to 250 volts •Very high current continuous operation capability ••Small footprint •Low clearance height ••Low cost ••Parts available in broadband and low frequency materials •Lighter, smaller and less susceptible to vibration than older wire wound chokes Applications: •EMI suppression intended for use prior to a fusable link in conducted and radiated EMI applications in high and low-frequency power supplies •Excellent in telecommunications, automotive and appliance applications B A G Normal Mode Impedance is the total impedance to the differential circuit (both out and back). Open Circuit Impedance is the impedance measured across a single leg of the common mode choke. Common Mode Impedance is the impedance of EMI noise conducted in the same direction along two conductors.
