B0505S-1WR3 Description

Short technical summary and product information.

The B0505S-1WR3 is an isolated DC/DC converter module manufactured by Morning Star Industrial. It provides a single regulated 5V output at 200mA from a nominal 5V input, with a power rating of 1W. The module features an efficiency of up to 82% and is designed for ITE (commercial) applications.

 

The converter is housed in a compact 4-SIP through-hole package measuring 0.46" L x 0.24" W x 0.40" H (11.6mm x 6.0mm x 10.2mm). It operates over a temperature range of -40°C to 105°C with derating. The module offers isolation between input and output, making it suitable for applications requiring ground loop elimination or voltage level shifting.

 

The B0505S-1WR3 carries CE and cURus safety approvals and is listed as RoHS3 compliant. Its compact footprint and through-hole mounting facilitate integration into various power supply designs.
