Product Description
The RS PRO PCB Transformer model 121-3836 is a high-quality, low-profile transformer designed for PCB applications requiring safe and efficient voltage transformation. It is engineered to deliver two independent 9 V AC outputs, allowing for flexible integration into electronic circuits. The device features dual primary windings, enabling operation with either 115 V or 230 V AC input, giving designers the option to wire for regional voltage compatibility.
This transformer provides a rated output power of 4 VA, which makes it suitable for a wide range of low voltage power supply and signal conditioning applications. It offers compact dimensions - 53 mm length, 44 mm width, and 23 mm depth - making it ideal for electronics with restricted board space or height limitations. The low height and efficient design ensure minimal temperature rise during operation, supporting continuous performance in demanding environments.
The component is equipped with 20 pins for secure PCB mounting and easy installation. It maintains a high isolation voltage of 3.75 kVrms between primary and secondary for enhanced safety. Independent secondary windings support both series and parallel connection options, allowing designers flexibility in configuring output voltage and current to meet specific needs.
Engineered for reliability, this transformer can operate within a temperature range up to 130°C and a frequency range of 50 Hz to 60 Hz. It incorporates two-compartment bobbins, providing low interwinding capacity and reduced radiated noise. Each transformer is 100% electrical and flash tested, ensuring product quality and operational safety.
Use cases include isolated low voltage power supplies, signal interface circuits, and other scenarios requiring PCB-mounted AC voltage transformation.
