A187A12C audio input transformers from OEP provide galvanic isolation and are constructed with multiple electrostatic and magnetic shields. They feature a low distortion core and reduce the audio hum and buzz between the ground at the send and receive terminations of the signal. Proof voltage of 250 Vrms from windings to screen and from primary to secondary. 140 pF interwinding capacitance at 20 Hz (primary to screens and secondary to screens). 1.2 mH primary leakage inductance at 1 kHz. 2.82 H nominal inductance for each winding Primary Impedance = 600Ohms Secondary Impedance = 600Ohms Primary DC Resistance = 49.8Ohms Secondary DC Resistance = 48.5Ohms Dimensions = 29.4 x 25 x 24.2mm Mounting Type = Through Hole Termination Type = PC Pin Weight = 56g Depth = 24.2mm Length = 29.4mm
