Common mode choke with ferrite core N27, tin-plated brass pins, plastic body, copper windings, 1:1 ratio, 153 turns, 3.37–4.12 L/mH at 10 kHz, handles less than 1 kVA, blocks common-mode noise and electromagnetic interference while allowing differential currents to pass.
Description : Common Mode Choke With a power handling capacity of less than 1KVA, ratio 1 to 1 , 153 turns, 3.37-4.12 L/MH, 10KHZ. Core is ferrite, type N27. Pins are tin plated brass. Body is plastic. Windings are copper. Used for the removal or decreasing noise or related electromagnetic interference. Common mode chokes allow differential currents to pass while blocking signals that are affecting both wires. Because the magnetic flux produced by differential-mode currents in the core of a common mode choke tend to cancel each other out, the choke presents little impedance to differential mode currents.
