The SCWN06B-03 is an isolated DC/DC converter manufactured by Mean Well. It is a 6W device with an input voltage range of 18-36V, and can output a 3.3V voltage with up to 1200mA of current. It is designed to fit a Dual Inline Package (DIP) with 24 pins. Additionally, this device is fully isolated, meaning there are two separate circuits, one inside and one outside, with no electrical connection between them. The isolation ensures that the external circuit is electrically shielded from the internal circuit, offering EMI protection. It is ideal for control, communications, and automotive applications that need robust protection against highvoltage spikes.
