TRF 4899 PCB Transformer 5.5VA 2x7.2VAC 2x380mA Through Hole

The TRF 4899 PCB Transformer is a compact through-hole PCB transformer designed to provide dual 7.2VAC secondary outputs for low-power electronic circuits, instrumentation, automation systems, and power supply applications. With a 5.5VA power rating and dual 7.2V secondary windings rated at 380mA each, it is ideal for applications requiring isolated or symmetrical AC power sources.

The dual secondary configuration provides greater design flexibility, allowing the transformer to be used for split-rail power supplies, bipolar voltage circuits, audio electronics, and other applications requiring dual AC outputs. Depending on circuit requirements, the secondary windings may also be connected in series or parallel where appropriate.

Designed for direct PCB mounting, the TRF 4899 reduces wiring complexity while saving valuable board space. Its encapsulated construction provides reliable electrical isolation between the primary and secondary windings, ensuring safe and dependable long-term operation in commercial, industrial, and OEM equipment.

The 7.2VAC outputs are ideal for rectification and voltage regulation, making the transformer suitable for embedded systems, battery charging circuits, control electronics, and general-purpose AC power supplies.
