1274AS-H-4R7N=P3 Description

Short technical summary and product information.

This is a shielded wirewound inductor from Murata, part of the 1274AS-H series. It features a ferrite core and drum core construction, providing a nominal inductance of 4.7µH with a tolerance of ±30%. The component is designed for surface mount assembly in a nonstandard package measuring 10.00mm x 10.00mm x 5.00mm.

 

Electrical characteristics include a maximum DC resistance of 13.5mOhm. The rated current is specified under two conditions: 6.4A typical based on a 30% inductance drop, and 9.5A typical based on a 40°C temperature rise. The inductor is shielded to minimize electromagnetic interference.

 

This inductor is suitable for power supply circuits, DC-DC converters, and other applications requiring high current handling with low DC resistance. The surface mount package allows for automated assembly. The component is RoHS3 compliant and has an MSL of 1 (unlimited). Note that compliance status is unverified.
