15M473JLF

Overview

The 15M473JLF is a fixed inductor from Gowanda Electronics, classified as a molded unshielded RF coil with axial leads. It features an iron powder core and offers a nominal inductance of 470 µH with a tolerance of ±5%. The component has a maximum DC resistance of 17.9 Ω and a rated current of 67 mA. It operates within a temperature range of -55 °C to +125 °C. The package dimensions are approximately 9.525 mm in length by 3.962 mm in diameter, weighing 0.65 grams.

Feature Summary

• Molded construction provides mechanical stability for axial lead mounting
• Iron powder core material supports high-frequency RF applications
• Unshielded design allows for flexible circuit layout integration

Applications

• Radio frequency filtering circuits
• General purpose inductive components
• Aerospace electronic systems
• Defense communication equipment

Procurement Notes

Verify RoHS compliance status carefully as the 15M series may contain lead. Confirm axial lead spacing matches PCB footprint requirements. Check operating temperature limits against system thermal profiles. Ensure unshielded design does not interfere with nearby sensitive components due to magnetic field exposure.

Selection Notes

Select this model when high inductance values are required in a compact axial package. Consider the 17.9 Ω DC resistance impact on circuit efficiency. Verify that the 67 mA current rating meets application load demands. Compare against shielded alternatives if electromagnetic interference mitigation is necessary.

Part Context

Part of the 15M series of molded unshielded RF coils designed by Gowanda Electronics. This series targets demanding aerospace and defense environments requiring reliable passive components. The axial configuration facilitates through-hole mounting techniques common in ruggedized electronics manufacturing.

Replacement Considerations

Cross-reference with other 15M series variants such as 15M473J for non-RoHS versions. Consult Gowanda official documentation for direct substitutes with identical electrical parameters and physical dimensions.
