The FS28-700 series from Triad Magnetics, Inc., consists of power transformers designed for a variety of low-power applications requiring specific voltage and current outputs. These transformers are particularly useful in systems that need to step down voltages from 115V or 230V to more manageable levels, such as 28V at 0.7A and 14V at 1.4A, while providing a total output of 20VA.

If you're working on medical devices, industrial control panels, or any equipment that needs regulated power supplies, these transformers are a go-to component. They come in an 8-pin configuration, making them easy to integrate into PCB designs. One thing worth noting is their Class 2/3 rating, which provides additional safety by isolating the secondary circuit from the primary, making them suitable for environments where electrical isolation is critical.

Engineers tend to reach for this when they need a compact solution that can handle both lower and higher output requirements efficiently. The FS28700C2 and its through-hole counterpart, the FS28700C2B, offer reliable performance in a wide range of applications, ensuring consistent power delivery without the need for complex external regulation circuits.
