The component has a maximum DC resistance of 250 mOhms and supports a maximum DC current of 435 mA. Designed for PCB mounting, it operates within a temperature range up to 105 °C. The unit measures 5.08 mm in length and 1.98 mm in diameter, utilizing standard axial terminals.

Feature Summary

• Molded unshielded coil design for general purpose RF applications
• Iron core construction providing stable inductance characteristics
• Axial leaded termination style suitable for through-hole PCB mounting

Applications

• RF circuit filtering
• General purpose inductive components
• Signal processing circuits

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets may be managed by other entities. Confirm RoHS compliance status, as historical data indicates mixed availability between compliant and non-compliant variants. Ensure the ordering suffix matches the required tolerance and packaging configuration. Cross-reference terminal dimensions against the target PCB layout requirements prior to procurement.

Selection Notes

Select this component when a low-inductance value near 1 µH is required for RF signal paths. The unshielded design necessitates careful placement to avoid magnetic coupling with adjacent components. Verify that the operating current remains below the 435 mA limit to prevent saturation or thermal issues. Consider the physical dimensions for board space constraints during the initial schematic capture phase.

Part Context

This part belongs to the 0819 series of fixed RF inductors manufactured by Delevan. The series utilizes molded unshielded coils with axial leads, designed for robust performance in radio frequency environments. Components in this family typically feature iron cores and are optimized for general-purpose inductive applications requiring precise inductance values.

Replacement Considerations

The 0819R-18H serves as a related alternative within the same product family, offering similar construction but different electrical parameters.
