17S392KLF

Fixed Inductors Overview

The 17S392KLF is a shielded, molded axial lead RF inductor manufactured by Gowanda Electronics. It features a nominal inductance of 39 µH with a tolerance of ±10%. The component has a maximum DC resistance of 1.93 Ω and a minimum quality factor of 45 at a test frequency of 2.5 MHz. Its self-resonant frequency is 22 MHz, and it supports a maximum rated current of 125 mA. Designed for surface mount or through-hole integration via axial leads, it operates within a temperature range suitable for industrial applications.

Fixed Inductors Feature Summary

• Shielded molded construction minimizes electromagnetic interference
• Axial lead configuration facilitates standard mounting processes
• Ferrite core design optimized for radio frequency stability

Fixed Inductors Applications

• Radio frequency filtering circuits
• Impedance matching networks
• General purpose RF signal conditioning

Fixed Inductors Procurement Notes

Verify the specific RoHS compliance status and lead finish (tin vs. lead) against the latest manufacturer datasheet, as legacy variants may differ. Confirm axial lead dimensions and shielding integrity requirements for your PCB layout. Ensure the 125 mA current rating meets circuit demands to prevent saturation. Cross-reference the 22 MHz self-resonant frequency with your operating band to avoid harmonic issues.

Fixed Inductors Selection Notes

Select this component when axial mounting is preferred over surface mount for mechanical stability in RF environments. The 39 µH value suits intermediate frequency stages. Consider the 1.93 Ω DC resistance impact on voltage drop. The shielded design is critical if adjacent components require isolation. Verify thermal performance at the maximum rated current.

Fixed Inductors Part Context

This part belongs to Gowanda's 17S series of shielded molded RF coils. The series offers various inductance values with consistent axial lead formats. Gowanda specializes in high-reliability magnetic components for aerospace, defense, and medical sectors. The 17S series emphasizes robust shielding and stable RF performance under varying conditions.

Fixed Inductors Replacement Considerations

Direct substitutes include other 39 µH ±10% axial RF inductors from Gowanda such as the 17S392JLF if tighter tolerance is acceptable. Verify physical footprint compatibility. Check if alternative manufacturers offer equivalent shielding and Q-factor specifications.
