K7805-500R3 Description

Short technical summary and product information.

The MORNSUN K7805-500R3 is a high-efficiency linear regulator replacement DC-DC converter designed for industrial and commercial applications. It provides a regulated 5V output from a 6.5V to 7V input, delivering up to 500mA of output current and 4W of power.

 

With an efficiency of 90%, this converter minimizes power loss and heat generation, making it ideal for space-constrained designs. The component features short-circuit protection (SCP) and operates over a temperature range of -40°C to 85°C with derating.

 

Housed in a compact 3-SIP (Single In-line Package) module, the K7805-500R3 is designed for through-hole mounting, allowing easy integration into PCB designs. Its dimensions are 11.6mm x 7.6mm x 10.2mm, suitable for applications where board space is limited.

 

This converter is approved by CB, CE, and cURus, and is suitable for ITE (commercial) applications. The unverified RoHS, REACH, and MSL status should be confirmed with the manufacturer for compliance verification.
