0819-12F

Overview

The Delevan 0819-12F is a leaded RF inductor from the 0819 series, featuring an axial termination and unshielded molded construction. It provides an inductance of 330 nH with a tight 1% tolerance and a maximum DC resistance of 490 mOhms. The component supports a maximum DC current of 750 mA and achieves a minimum Q factor of 30 at a self-resonant frequency of 260 MHz. Designed for PCB mount applications, 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 style for through-hole mounting
• High precision 1% inductance tolerance

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF signal processing

Procurement Notes

Verify the specific manufacturer designation, as sources indicate API Delevan production. Confirm RoHS status, which is listed as non-compliant in official specifications. Ensure the ordering quantity aligns with the reel packaging requirements typically associated with this component series.

Selection Notes

Select this component when a low-inductance value near 330 nH is required with high accuracy. The unshielded design necessitates careful layout to prevent magnetic coupling with nearby components. Verify that the operating frequency remains below the 260 MHz self-resonant point for stable performance.

Part Context

This part belongs to the Delevan 0819 series of molded RF inductors. These components are characterized by their small axial form factor and unshielded construction, making them suitable for space-constrained RF designs where magnetic shielding is not strictly required or managed via layout.
