0819-92K

Overview

The Delevan 0819-92K is a fixed axial leaded RF inductor designed for molded unshielded coil applications. It features an iron core and provides an inductance of 680 µH with a tolerance of ±10%. The component has a maximum DC resistance of 66 Ohms and supports a maximum DC current of 27 mA. Its self-resonant frequency is specified at 4.5 MHz, suitable for radio frequency circuits. The device utilizes standard axial termination and is packaged on reels for surface or PCB mounting.

Feature Summary

• Molded unshielded construction with iron core
• Axial leaded termination for PCB integration
• Optimized for radio frequency signal processing

Applications

• Radio frequency circuit filtering
• RF impedance matching networks
• General purpose RF inductive components

Procurement Notes

Verify RoHS compliance status as the product is listed as non-compliant in available documentation. Confirm manufacturing origin and specific reel packaging quantities directly with API Delevan or authorized distributors before ordering. Ensure the axial lead length and diameter meet your PCB footprint requirements. Check for any updated environmental declarations or alternative compliant series if restricted materials are prohibited in your final assembly.

Selection Notes

Select this component when a high-inductance value of 680 µH is required in a compact axial form factor. The unshielded design necessitates careful layout to prevent magnetic coupling with adjacent sensitive traces. Consider the 27 mA current limit and 66 Ohm DC resistance for power handling constraints. This part is suitable for low-current RF applications where shielding is not strictly mandated by the system architecture.

Part Context

The 0819 series represents a line of fixed RF inductors manufactured by API Delevan. These components are characterized by their molded epoxy construction and axial leads, distinguishing them from SMD variants like the M0820 series. The 0819-92K specifically denotes the 680 µH variant within this family, sharing physical dimensions and termination styles with other values in the 0819 range.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source data. Verify mechanical compatibility and electrical equivalence with other 680 µH axial inductors if direct substitution is required.
