0819-38J

Overview

The Delevan 0819-38J is a leaded RF inductor featuring an axial termination style and unshielded molded construction. It provides an inductance of 3.9 µH with a tolerance of ±5%. The component supports a maximum DC current of 178 mA and exhibits a maximum DC resistance of 1.5 Ohms. Designed for PCB mounting, it measures 5.08 mm in length and 1.98 mm in diameter. The unit operates within standard terminal configurations and is packaged in reels for automated assembly processes.

Feature Summary

Molded unshielded coil construction for consistent RF performance
Axial leaded termination optimized for through-hole PCB mounting
Standard terminal configuration ensuring reliable electrical connection

Applications

RF circuit design
PCB mount applications
Leaded inductor implementations

Procurement Notes

Verify the specific manufacturer part number against official Delevan documentation to confirm exact electrical parameters and physical dimensions. Ensure that the axial leaded form factor aligns with the target PCB layout requirements. Confirm packaging specifications match production needs, as reel quantities may vary by distributor. Cross-reference datasheet values for inductance, current rating, and resistance prior to final integration.

Selection Notes

Select this component when an unshielded axial inductor with 3.9 µH nominal value is required for RF applications. Consider the 178 mA current rating and 1.5 Ohm resistance limits during circuit analysis. The molded construction offers mechanical stability for through-hole mounting. Verify that the unshielded nature does not interfere with nearby sensitive components due to potential magnetic field radiation.

Part Context

This component belongs to the Delevan 0819 series of RF inductors. The series features molded unshielded coils with axial leads, designed for general-purpose RF filtering and tuning. These inductors are characterized by their compact cylindrical body and standard lead spacing, facilitating easy insertion into printed circuit boards for various electronic assemblies.
