Bring compact AC conversion onto the circuit board

Small electronic projects work best when the power components fit the board layout from the start. This encapsulated PCB transformer places a 1.2VA AC conversion component in a compact four-pin package, with listed 6V, 9V and 12V AC output choices for compatible designs.

Key Benefits

• Board-mount four-pin design — Integrate the component into a matching PCB footprint instead of adding a separate plug-in wall adapter.
• Encapsulated housing — The compact blue casing keeps the transformer in one easy-to-position component package.
• Selectable order configurations — Choose the listed fixed-output version your circuit needs, rather than assuming one transformer adjusts between voltages.
• 1.2VA rating — Provides a defined apparent-power specification for appropriately sized low-power AC designs.
• Two-piece standard choices — The 6V, 9V and 12V order options each list two pieces, useful for a pair of matching boards or a replacement component.

For an electronics repair bench or a planned PCB build, this component offers a tidy board-level format. Use the dimensional and pin-layout drawing alongside the circuit design so the selected output version belongs in the intended assembly.

Frequently Asked Questions

Is the output AC or DC?

The listed outputs are AC. This is not a finished regulated DC power supply; circuits requiring DC need appropriately designed rectification, filtering and regulation.

What input voltage is listed?

The available input option is 220V AC. It is not listed as a universal 100–240V input component.

Can I switch one unit between 6V, 9V and 12V?

No adjustable selector is shown. These are separate fixed-output purchase options, so select the version required by the circuit.

How many pieces are included?

The standard output choices explicitly list two pieces for 6V, 9V or 12V. The separate custom-voltage choice does not establish a specific output or quantity; those details require confirmation before that configuration can be fulfilled accurately.

Can I connect this directly as a household adapter?

No. It is a mains-connected PCB component for qualified electronics assembly, not a ready-to-use wall charger. The completed design needs appropriate insulation, fusing, enclosure and verified pin connections.
