0819-12H

Overview

The Delevan 0819-12H is a leaded RF inductor featuring an axial termination style and unshielded molded construction. It provides an inductance of 330 nH with a tolerance of 3%. The component supports a maximum DC current of 460 mA and has a maximum DC resistance of 490 mOhms. Key electrical characteristics include a minimum Q factor of 40 and a self-resonant frequency of 500 MHz. Designed for PCB mounting, it measures 5.08 mm in length and 1.98 mm in diameter.

Feature Summary

• Molded unshielded coil design for RF applications
• Axial leaded termination for standard PCB mounting
• High self-resonant frequency capability

Applications

• RF circuit filtering
• Impedance matching networks
• General radio frequency signal processing

Procurement Notes

Verify the specific manufacturer source, as API Delevan assets are often managed by other entities. Confirm RoHS compliance status directly with the supplier, as documentation varies. Ensure the ordering quantity aligns with factory reel requirements if applicable. Cross-reference the datasheet revision to confirm the 490 mOhm DCR specification matches your design constraints.

Selection Notes

Select this component when a compact, unshielded axial inductor is required for frequencies near 500 MHz. The 330 nH value suits intermediate RF stages. Consider the 460 mA current limit for power handling. Compare against the 0819R series if a different tolerance or packaging format is needed. Verify physical clearance for the 5.08 mm length on the target PCB layout.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. These components are characterized by their molded epoxy construction and axial leads. The series offers various inductance values tailored for radio frequency environments. They are distinct from shielded variants which provide tighter magnetic containment but may have different self-resonant characteristics.
