0819-36F

Overview

The Delevan 0819-36F is a fixed axial leaded RF inductor with a nominal inductance of 3.3 µH and a tight tolerance of ±1%. It features an unshielded molded construction using an iron core, resulting in a maximum DC resistance of 1.2 Ohms and a minimum Q factor of 45 at its self-resonant frequency of 100 MHz. The component supports a maximum DC current of 198 mA and is designed for PCB mount applications. Physical dimensions include a length of 5.08 mm and a diameter of 1.98 mm.

Feature Summary

• Unshielded molded coil design suitable for general RF circuit integration
• Axial leaded termination style facilitating through-hole PCB mounting
• Iron core construction providing stable inductance characteristics

Applications

• RF signal processing circuits
• Impedance matching networks
• Filtering applications in radio frequency systems

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets may be managed by other entities. Confirm RoHS compliance status, as documentation indicates non-compliance. Ensure the ordering suffix matches the required reel packaging quantity. Cross-reference the datasheet to confirm the exact DC resistance and current ratings for the specific production batch.

Selection Notes

Select this component when a precise 3.3 µH inductance with high accuracy is required for RF applications. The unshielded design necessitates careful layout consideration to prevent magnetic coupling with adjacent components. Verify that the operating current remains below the 198 mA limit to maintain performance integrity.

Part Context

This part belongs to the 0819 series of fixed RF inductors manufactured by Delevan. The series offers various inductance values tailored for radio frequency applications. The 0819-36F specifically provides a mid-range inductance value with tight tolerance, distinguishing it from lower or higher inductance variants within the same product family.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Equivalent parts must match the 3.3 µH inductance, ±1% tolerance, and axial package form factor. Verify that alternative components meet the 100 MHz self-resonant frequency requirement.
