0819-14G

Overview

The Delevan 0819-14G is a fixed axial leaded RF inductor featuring a molded unshielded coil construction. It provides an inductance of 390 nH with a tolerance of 2%. The component supports a maximum DC current of 420 mA and exhibits a maximum DC resistance of 590 mOhms. Designed for PCB mounting, it measures 5.08 mm in length and 1.98 mm in diameter. This part belongs to the 0819 series and is intended for radio frequency applications requiring stable inductance in compact circuits.

Feature Summary

• Molded unshielded coil design for stable inductance
• Axial through-hole termination style
• Compact physical dimensions suitable for space-constrained layouts

Applications

• Radio frequency circuit filtering
• Impedance matching networks
• RF signal processing stages

Procurement Notes

Verify the specific manufacturer designation, as API acquired Delevan's passive components business. Confirm that the ordering suffix matches the required tolerance and electrical parameters. Ensure the procurement source provides valid datasheets confirming the 390 nH value and 420 mA rating. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a 390 nH inductance is required with low DC resistance for moderate current levels. The unshielded design requires careful layout consideration to prevent magnetic coupling with nearby traces. Verify that the self-resonant frequency characteristics align with the target operating band. Compare against other 0819 series variants if different inductance values or current ratings are needed.

Part Context

The 0819 series represents a line of molded axial RF inductors from Delevan (now API Delevan). These components are characterized by their consistent performance in radio frequency environments. The 0819-14G specifically targets applications needing precise low-nanohenry inductance. The series maintains standardized mechanical dimensions across variants, facilitating board layout consistency.

Replacement Considerations

Direct substitutes within the same series include 0819-16G (470 nH) or 0819-10F (270 nH) if inductance adjustments are permissible. Cross-brand replacements require matching the 390 nH value, 420 mA current rating, and axial package dimensions. Verify that alternative components meet the same RF performance criteria.
