0819-40G

Overview

The Delevan 0819-40G is a fixed axial leaded RF inductor with molded unshielded construction. It features an inductance of 4.7 uH, a tolerance of 2%, and a maximum DC resistance of 2.1 Ohms. The component supports a maximum DC current of 150 mA and exhibits a minimum Q factor of 45 at its self-resonant frequency of 60 MHz. Designed for PCB mount applications, it measures 5.08 mm in length and 1.98 mm in diameter.

Feature Summary

• Molded unshielded coil construction for standard RF circuit integration
• Axial leaded termination style suitable for through-hole PCB mounting
• High Q factor performance optimized for radio frequency signal processing

Applications

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

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm axial lead dimensions match target PCB layout requirements. Ensure operating current remains below the 150 mA maximum rating to prevent thermal issues. Validate supplier authenticity against API Delevan manufacturing records before purchase.

Selection Notes

Select this component when a 4.7 uH inductance value is required with tight 2% tolerance. Choose over shielded variants if magnetic interference isolation is not critical. Consider the 2.1 Ohm DC resistance impact on circuit efficiency. Verify self-resonant frequency alignment with target RF band operations.

Part Context

Part of the Delevan 0819 series of fixed RF inductors. Shares physical dimensions with other series members like 0819-36F and 0819-16G. Manufactured by API Delevan specializing in high-frequency passive components. Distinct from the 0819R series which may offer different electrical characteristics.

Replacement Considerations

Cross-reference with 0819-40J for similar 4.7 uH specifications. Check 0819-48F if higher inductance is acceptable. Verify lead compatibility with existing assembly processes.
