0819-50J

Overview

The Delevan 0819-50J is a leaded RF inductor from the 0819 series, designed for PCB mount applications. It features an axial termination style and an unshielded molded construction. The component has an inductance of 12 uH with a tolerance of 5%. It supports a maximum DC current of 126 mA and exhibits a maximum DC resistance of 3 Ohms. The minimum Q factor is specified at 40, with a self-resonant frequency of 27 MHz. Physical dimensions include a length of 5.08 mm and a diameter of 1.98 mm.

Feature Summary

• Molded unshielded coil construction for RF applications
• Axial leaded termination for through-hole PCB mounting
• Standard terminal configuration

Applications

• RF circuits
• Inductors, Chokes & Coils assemblies

Procurement Notes

Verify the manufacturer designation carefully, as sources list both API Delevan Inc. and Delevan. Confirm RoHS compliance status, as documentation varies between compliant and non-compliant designations across different distributors. Ensure the ordering suffix matches the required reel quantity if applicable. Cross-reference the datasheet version to confirm electrical parameters align with the specific production batch requirements.

Selection Notes

Select this component when a 12 uH inductance value is required with a 5% tolerance. The 126 mA current rating suits low-power RF signal paths. The unshielded design requires consideration for magnetic coupling in dense layouts. Verify that the 27 MHz self-resonant frequency meets the operational bandwidth needs of the target circuit application.
