15M391KLF

Overview

The 15M391KLF is a general-purpose axial lead inductor manufactured by Gowanda Electronics. It features an unshielded molded construction with a ferrite core, designed for radio frequency applications. The component has a nominal inductance of 3.9 µH with a tolerance of ±10%. It operates within a temperature range of -55 °C to +125 °C and supports a maximum DC current of 0.28 A. Key electrical parameters include a maximum DC resistance of 2.3 Ω and a self-resonant frequency of 100 MHz.

Feature Summary

• Unshielded molded design suitable for RF circuits
• Axial lead configuration for through-hole mounting
• Wide operating temperature range from -55 °C to +125 °C

Applications

• Radio frequency filtering
• High-frequency signal processing
• General purpose inductive circuits

Procurement Notes

Verify the specific suffix 'LF' indicates RoHS compliance when sourcing. Confirm that the axial package matches the target PCB layout requirements. Ensure the 0.28 A current rating meets the circuit's operational demands. Check for availability of datasheets directly from Gowanda Electronics to confirm latest specifications.

Selection Notes

Select this component for applications requiring a compact, unshielded axial inductor with a 3.9 µH value. Consider the 2.3 Ω DC resistance impact on power loss. The 100 MHz self-resonant frequency defines the upper operational limit. Verify compatibility with high-temperature environments up to 125 °C.

Part Context

This part belongs to Gowanda Electronics' line of molded unshielded RF coils. The series offers various inductance values in an axial package. These components are engineered for reliability in demanding electronic systems where standard shielding is not required or feasible.

Replacement Considerations

The GA20-391K is a similar 3.9 µH inductor but typically features higher current ratings. Verify if the lower current capacity of the 15M391KLF (0.28 A) is acceptable as a substitute. Cross-reference physical dimensions to ensure mechanical fit.
