ZXY EI10 Audio Transformer - EI10 Shell Type Core, 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 packing.

Overview This component is based on the EI10 shell-type core, secured by a black core clamp, wound with copper wire and wrapped in yellow insulation tape, mounted on a molded green bobbin with solder pins. The production unit is marked 24013G-T1B on the tape wrap. The body and pin layout are common across the series, so parts from the same series fit the same board-level footprint.

2. Feature

EI10 shell-type core. Secured by the black core clamp on both sides of the component.

Copper wire winding. The coil is covered with yellow insulation tape.

Molded green bobbin. With integrated through-hole pin base, so seating and soldering are done in one step.

Single-phase audio transformer. Used in electronic equipment.

Lead style: pins. For direct PCB mounting without sockets or flying leads.

Part marking 24013G-T1B. Printed on the tape wrap of each unit.

Compact profile. Suitable for high-density board layouts.

Series part. Supplied as part of the ZXY EI10 series precision audio transformers.

Carton packing. For bulk shipping.

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

3. Advantage

Compact profile. The EI10 package occupies a small area, which is important in assemblies where transformers share space with surface-mount components.

Taped coil. The yellow tape on the winding provides a consistent structure and protects the copper wire during handling; the winding remains visible through the opening in the upper bobbin cheek.

Rigid molded bobbin and pins. The pin base is part of the molded piece, so the pins stay aligned during through-hole soldering without drifting in a separate carrier.

Core clamp. The black clamp fixes the lamination stack, making the core mechanically stable and the gap consistent from unit to unit.

Shared mechanical footprint. The same body and pin layout across the EI10 series simplifies design-in, especially when multiple turn ratios are used on a board.

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

At macro level, the pin base is worth a second look. The pins come out of the molded piece rather than being inserted into a separate pin header, so their spacing is fixed by the mold and won't drift during soldering. On boards where the transformer sits close to surface-mount parts, this guarantees the part stays square to the pads.

4. Application

Audio and electronic equipment. Defined use for this model.

PCB-level audio. Pin terminals are mounted directly on the printed circuit board.

OEM audio components. Manufactured with the 24013G-T1B part marking shown on the drawing.

Compact audio products. The EI10 profile fits space-constrained board areas.

The board view shows the part in a design context: multiple units of the same profile on one assembly, sharing solder pads with surface-mount parts. Since the series keeps a common body, a board needing several transformers can still use the same footprint.
