ZXY EI10 Audio Transformer - EI10 Shell-Type Core with Black Clamp, Copper Winding with Yellow Tape, Molded Green Bobbin, DIP Through-Hole Pins, CCC CE RoHS UL

1. Product Name

ZXY EI10 audio transformer. ZXY EI10 Series precision audio transformer, single phase, DIP through-hole pins, carton packed.

Overview. The part is built on an EI10 shell-type core held by a black core clamp, wound with copper wire and taped in yellow insulation, and seated on a molded green bobbin that carries the solder pins. Production units are marked 24013G-T1B on the tape wrap. The body and pin arrangement are shared across the series, so parts of the same series drop into the same board footprint.

2. Feature

EI10 shell-type core. held by a black core clamp on both sides of the assembly.

Copper wire winding. insulated with yellow tape over the coil.

Molded green bobbin. with an integrated through-hole pin base, so the part is located and soldered in one operation.

Single-phase audio transformer. intended for electronic equipment.

Lead way: pins. for direct PCB mounting without a socket or flying leads.

Part marking 24013G-T1B. printed on the tape wrap of every unit.

Compact outline. suited to dense board layouts.

Series part. supplied as part of the ZXY EI10 Series of precision audio transformers.

Carton packaging. for bulk shipment.

The taped coil sits between the core halves, with the copper winding visible through the opening in the upper bobbin cheek, and a red dot on the bobbin face marks orientation. The black clamp holds the core assembly on both sides, and the molded base carries the solder pins.

3. Advantage

Compact outline. the EI10 footprint keeps board area usage low, which matters on assemblies where the transformer shares space with surface-mount parts.

Tape-wrapped coil. the yellow tape over the winding gives a consistent build and protects the copper during handling; the winding stays visible through the opening in the upper bobbin cheek.

Rigid molded bobbin and pins. the pin base is part of the moulding, so the pins stay aligned through through-hole soldering instead of drifting in a separate carrier.

Core clamp. the black clamp holds the lamination stack together, which keeps the core mechanically stable and the gap consistent from unit to unit.

Shared mechanical outline. the same body and pin arrangement across the EI10 series simplifies design-in when more than one ratio is used on a board.

Traceable marking. the 24013G-T1B marking on each unit supports production traceability.

The pin base is worth a second look in the macro. The pins come out of the moulding rather than being inserted into a separate header, so their spacing is fixed by the tool and cannot drift during soldering. On a board where the transformer sits next to surface-mount parts, that is what keeps the part square to its pads.

4. Application

Audio equipment and electronic devices. the usage defined for this model.

PCB-level audio stages. the pin terminals mount directly on printed circuit boards.

OEM audio assemblies. produced with the 24013G-T1B part marking shown on the artwork.

Compact audio products. the EI10 outline fits space-restricted board areas.

The board shots show the part in the context it is designed for: several units of the same outline on one assembly, sharing a pick-and-place footprint with surface-mount parts. Because the series keeps a common body, a board that needs more than one transformer still uses one outline.
