0819-66F

Overview

The Delevan 0819-66F is a leaded RF inductor featuring a molded unshielded coil construction with axial termination. It provides an inductance of 56 uH with a tight tolerance of 1% and a maximum DC resistance of 10 Ohms. The component supports a maximum DC current of 69 mA and maintains a minimum Q factor of 45. Its self-resonant frequency is specified at 11.5 MHz, suitable for radio frequency applications. The unit measures 5.08 mm in length and 1.98 mm in diameter, designed for PCB mounting.

Feature Summary

• Molded unshielded coil design for consistent RF performance
• Axial leaded termination for standard PCB integration
• High precision 1% inductance tolerance

Applications

• Radio frequency circuits
• RF filtering networks
• Impedance matching stages

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and material specifications. Ensure compatibility with RoHS directives if required by the end application. Confirm package type availability through authorized distribution channels prior to ordering.

Selection Notes

Select this component when precise 56 uH inductance is required for RF signal processing. The unshielded construction necessitates careful layout planning to minimize electromagnetic interference with adjacent traces. Verify that the 69 mA current rating aligns with the operational requirements of the target circuit stage.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. The series utilizes molded unshielded coils with axial leads, offering various inductance values and tolerance options for general-purpose RF applications. The 0819-66F represents a high-tolerance variant within this lineup.

Replacement Considerations

The 0819R-66J is a documented alternative within the same manufacturer portfolio, though it features a 5% tolerance compared to the 1% tolerance of the 0819-66F. Verify electrical equivalence before substitution.
