RAC05-05SK
Overview
The RAC05-05SK is a compact board-mount AC-DC power module that accepts a wide AC input range (85-264 VAC) and provides a regulated 5 V output at up to 1 A (5 W). It is supplied in a 1 inch x 1 inch footprint intended for PCB mounting where a small, self-contained mains power source is needed. The module simplifies powering embedded and industrial electronics without an external adapter.
Why Choose This Part
This 1 x 1 inch module gives a complete AC-to-5V solution in a very small PCB footprint, removing the need for separate wall adapters or bulky supplies. Its wide input range (85-264 VAC) makes designs easier to deploy globally without extra input-stage circuitry. Being a self-contained switching module simplifies thermal and EMC design compared with building a discrete supply from components.
Applications
Getting Started
Read the manufacturer's datasheet and recommended footprint before layout: follow input and output capacitor, fuse, and safety/clearance recommendations. Add an input fuse and an EMI filter if your application must meet conducted-emissions limits; place output decoupling close to the load. Test under worst-case ambient temperature and apply a dummy load when verifying regulation and startup behavior.
