0819-06K

Overview

The Delevan 0819-06K is a leaded RF inductor featuring an axial termination style and unshielded construction. It utilizes a phenolic core to achieve a nominal inductance of 0.27 µH with a tight tolerance of 3%. The component exhibits a maximum DC resistance of 0.21 Ohms and supports a maximum DC current of 705 mA. Key electrical characteristics include a minimum Q factor of 35 and a self-resonant frequency of 540 MHz. Designed for PCB mounting, it offers reliable performance for radio frequency applications requiring precise inductive values.

Feature Summary

• Axial leaded construction with unshielded design for flexible circuit integration
• Phenolic core material providing stable inductance characteristics
• High current handling capability suitable for power-intensive RF circuits

Applications

• Radio Frequency (RF) signal processing circuits
• Impedance matching networks in communication systems
• Filtering components in high-frequency electronic devices

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets have transitioned. Confirm RoHS compliance status directly with the supplier, as historical data varies. Ensure the axial lead length and diameter match your PCB layout requirements. Validate that the 705 mA current rating meets your circuit's operational demands without saturation.

Selection Notes

Select this component when a low-inductance value near 0.27 µH is required with high current capacity. The unshielded nature necessitates careful placement to avoid magnetic coupling with nearby sensitive components. Compare the 540 MHz self-resonant frequency against your operating range to ensure effective inductive behavior at the target frequency.

Part Context

This part belongs to the 0819 series of molded unshielded coils manufactured by Delevan. The series is characterized by axial leads and robust construction for through-hole mounting. It serves as a specialized solution for RF applications where standard shielded inductors are unnecessary or detrimental to thermal management.

Replacement Considerations

Direct substitutes within the same series include the 0819-10H, which shares similar physical dimensions but differs significantly in inductance and current ratings. Verify that any replacement maintains the required axial footprint and voltage isolation standards.
