15473C

Overview

The Murata Power Solutions 15473C is a radial leaded power inductor from the 1500 series. It features an unshielded wirewound construction with a ferrite core, designed for through-hole PCB mounting. The component provides an inductance of 47 µH with a tolerance of ±10%. It supports a rated current of 4.04 A and has a maximum DC resistance of 45.6 mΩ. The physical dimensions are 16 mm diameter by 21 mm height, with a 6 mm lead pitch and 0.8 mm lead diameter.

Feature Summary

• Radial leaded wirewound construction for robust through-hole integration
• Unshielded design utilizing a ferrite core for magnetic field management
• High current handling capability suitable for power filtering applications

Applications

• Power supply input/output filtering
• DC-DC converter circuits
• General purpose RF and power signal chokes

Procurement Notes

Verify the specific manufacturer part number against official Murata documentation to ensure compatibility with your circuit requirements. Confirm that the radial lead configuration and physical dimensions match your PCB footprint constraints. Check for any end-of-life or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a high-current radial inductor is required for power stages. Ensure the operating temperature range accommodates the application environment. Verify that the unshielded nature does not interfere with nearby sensitive components due to magnetic field exposure.

Part Context

This component belongs to the Murata 1500 series of leaded inductors. It is distinct from the discontinued 17473 model, which shares similar inductance values but differs significantly in current rating and physical specifications. The 15473C is engineered for higher current density compared to standard RF variants.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Cross-referencing with other manufacturers requires careful verification of electrical parameters and mechanical fit.
