ZXY EI41 Audio Transformer Low Frequency Silicon Steel Core Power Transformer
ZXY-14 Audio Isolation Transformer (marked “ZXY-14 AUDIO”), a compact audio coupling transformer built on a high-permeability laminated core and supplied as a dual matched pair for stereo and differential audio channels. Each unit measures 18 × 14 × 25 mm overall and is fitted with 75 mm flexible pure-copper lead wires, colour-coded Red for one winding and Blue for the other. A dot marking identifies the start point of each winding, so polarity can be confirmed at a glance du

PQ3220 High Frequency Transformer, Low-Loss Ferrite Core, 12-Pin PCB Through-Hole Mount, 34.5 x 36.0 x 23.0 mm, 100-500 kHz SMPS, Custom Windings
PQ3220 is the core size, not a winding. The part is a high frequency transformer built on a PQ3220 ferrite core with a twelve-post PCB termination, intended for switching supplies running between 100 kHz and 500 kHz. Because the winding is made to order, the model number fixes the core, the frame, the pinout and the envelope; the primary and secondary are then wound to the ratio and the inductance the customer's circuit needs.

SMD Audio Isolation Transformer, ED8-600 Ohm to 600 Ohm, 1:1, 6-Pin Surface Mount, 10.5 mm, 1250 V AC Hi-Pot
A 600 ohm to 600 ohm audio isolation transformer in a surface mount package. The two windings are 1:1, so the part is a galvanic break in a line level path rather than a matching transformer: the voltage across it stays where it was, and only the ground connection between the two sides disappears. Six gull-wing pins, three to each side, put it on the board like any other SMD part, which is the reason it exists next to the cased parts it replaces.
