Product Description

Block PT 4.5/2/9 PCB Transformer is a high quality electronic component designed for reliable voltage transformation on printed circuit boards. It features a primary voltage rating of 230 V AC with dual secondary outputs delivering 9 V AC at 4.5 VA power. This transformer is mounted using a through-hole design measuring 44mm in length, 33mm width, and 37mm depth, facilitating secure installation.

The transformer incorporates a dual secondary winding configuration along with a single primary winding, allowing parallel or series connections as required by the application. It includes an internal Positive Temperature Coefficient (PTC) device that provides inherent short circuit protection, increasing safety and durability.

Encased in vacuum epoxy resin rated UL94-V0 for flame retardance and formed on double-section glass fiber reinforced polyamide bobbins, this component offers excellent electrical insulation and mechanical strength. The low operating temperature rise and 65% efficiency ensure reduced energy loss and prolonged component life under continuous operation up to a maximum temperature of 40°C.

Meeting international standards such as VDE and UL, this transformer is suitable for use in industrial, communications, power supply, and electronic control circuits. Its compact size and robust design make it ideal for dense PCB layouts where reliability and safety are paramount.

Dual secondary windings and single primary winding for versatile connections. Through-hole mounting for secure attachment on PCB assemblies. Vacuum epoxy resin moulded with UL94-V0 rating for high fire resistance. Internal PTC device offers short circuit proof protection.

Double-section glass fiber reinforced polyamide bobbins ensure durability. Efficient power handling with 65% efficiency and low thermal rise. Complies with VDE and UL safety approvals for global applications. Compact dimensions: 44mm x 33mm x 37mm enable space-saving design.

Manufactured in Germany ensuring top manufacturing quality.
