15M471K

Overview

The Gowanda Electronics 15M471K is a fixed inductor designed for radio frequency applications. It features an inductance of 4.7 µH with a tolerance of ±10%. The component has a maximum DC resistance of 2.6 Ohms and a rated DC current of 260 mA. It exhibits a self-resonant frequency of 90 MHz. The physical construction utilizes a molded phenolic core with axial leads, housed in a non-standard package configuration.

Feature Summary

• Unshielded molded RF coil design
• Axial lead configuration for through-hole mounting
• Phenolic core material construction

Applications

• Radio frequency circuit filtering
• Impedance matching networks
• General purpose RF signal processing

Procurement Notes

Verify the specific suffix requirements when ordering, as variants such as 15M471KLF exist. Confirm that the standard 15M471K designation aligns with the required lead finish and RoHS compliance status for your specific assembly process. Cross-reference the datasheet to ensure the axial lead style matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a 4.7 µH inductance value is required for RF stages with moderate current demands up to 260 mA. The unshielded design necessitates careful placement to avoid magnetic coupling with nearby sensitive components. Ensure the operating environment does not exceed the thermal limits associated with the molded phenolic construction.

Part Context

This part belongs to Gowanda's 15M series of molded unshielded RF coils. The company specializes in high-performance magnetic components for aerospace, defense, and industrial sectors. The 15M series provides reliable performance for critical RF applications where standard commercial inductors may not meet stringent quality or environmental standards.

Replacement Considerations

The 15M471KLF serves as a verified lead-free variant of this component. When substituting, confirm that the lead-free version maintains identical electrical parameters and mechanical dimensions. Other Gowanda models in the 15M series may offer different inductance values but share similar construction characteristics.
