105-561G

Overview

The Delevan 105-561G is a fixed surface-mount RF inductor with an inductance of 560 nH and a tolerance of 2%. It features a maximum DC current rating of 460 mA and a maximum DC resistance of 450 mOhms. The component operates within a self-resonant frequency range up to 47 MHz, ensuring stability in high-frequency applications. Designed for through-hole or SMT mounting depending on variant specifications, it provides reliable performance for RF circuit filtering and impedance matching tasks.

Feature Summary

• Molded construction for mechanical durability
• Shielded design to minimize electromagnetic interference
• Axial lead termination for through-hole integration

Applications

• RF signal filtering circuits
• Impedance matching networks
• High-frequency oscillators

Procurement Notes

Verify the specific package type and termination style against your PCB layout requirements, as variations exist between SMD and axial lead versions within the same series. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory details may vary by production batch. Ensure that the selected variant matches the required self-resonant frequency and current handling capabilities for your specific application environment.

Selection Notes

Select this component when a precise 560 nH inductance is required for RF applications with moderate current demands. Consider the physical dimensions and mounting style compatibility with your assembly process. Evaluate the Q factor and self-resonant frequency to ensure they meet the operational bandwidth requirements of your circuit design without introducing unwanted harmonic distortions.

Part Context

This part belongs to the API Delevan fixed inductor family, known for precision RF components. The 105 series typically includes various inductance values tailored for radio frequency and microwave applications. These components are engineered for consistency in electrical characteristics across temperature ranges, supporting stable performance in communication systems and test equipment.

Replacement Considerations

Direct substitutes include other 560 nH RF inductors from API Delevan such as the 105R-561G, provided the termination style and shielding requirements match. Cross-reference with similar series like 105-561GS if surface mount packaging is preferred over axial leads. Always verify pinout compatibility and thermal ratings before substitution.
