15472C

Overview

The Murata Power Solutions 15472C is an unshielded wirewound power inductor with radial vertical cylinder packaging. It features a nominal inductance of 4.7 µH and a tolerance of ±20%. The component supports a maximum DC current of 11.7 A with a maximum DC resistance of 6.48 mΩ. Designed for through-hole PCB mounting, it operates within a temperature range of -40°C to +125°C. The unit utilizes ferrite core material and standard soldering termination methods.

Feature Summary

• High current handling capability suitable for power filtering applications
• Unshielded wirewound construction for robust performance
• Radial leaded format facilitating through-hole PCB integration

Applications

• Power supply input/output filtering
• DC-DC converter circuits
• General power electronics signal conditioning

Procurement Notes

Verify the specific datasheet version before procurement as this component may be subject to obsolescence notices by the manufacturer. Confirm that the 11.7 A rating aligns with your thermal management design. Ensure the unshielded nature does not interfere with nearby sensitive components due to potential magnetic field emission during operation.

Selection Notes

Select this component when high current capacity is required in a radial form factor. The low DC resistance minimizes power loss at high currents. Consider the unshielded design implications for electromagnetic interference if used in dense layouts. Verify that the 4.7 µH value meets the specific ripple current requirements of the target power stage.

Part Context

This part belongs to Murata's leaded inductor portfolio, designed for industrial and commercial power applications. It serves as a discrete passive component for energy storage and filtering in power conversion topologies. The radial package allows for easy manual or wave soldering processes on printed circuit boards.

Replacement Considerations

Check for official replacement part numbers from Murata Power Solutions as the original model may be discontinued. Ensure any substitute maintains the 4.7 µH inductance, 11.7 A current rating, and compatible physical dimensions for direct PCB footprint compatibility.
