3VA PCB TRANSFOMER 12V

Description

The 3VA PCB Transformer 12V is a compact step-down power transformer designed for PCB mounting applications. It converts AC mains voltage (typically 110V/220V AC) into a stable 12V AC output, commonly used in low-power electronic circuits, control boards, and power supply modules.

Key Features

• Compact PCB-mount design for easy circuit integration
• Step-down transformation from AC mains to low-voltage AC
• Stable output suitable for regulated power supply circuits
• High efficiency with low core losses
• Durable laminated core construction
• Low noise and minimal vibration operation
• Suitable for continuous operation in electronic devices
• Easy solder pin mounting on PCB
• Safe isolation between primary and secondary windings
• Widely used in power supply and control circuits
