0819-18K

Overview

The Delevan 0819-18K is a fixed axial leaded inductor designed for general-purpose and RF applications. It features an unshielded molded construction with an iron core, resulting in a nominal inductance of 0.56 µH (560 nH) with a tolerance of ±10%. The component has a maximum DC resistance of 0.18 Ω and a current rating of 510 mA. It operates within a temperature range of -55 °C to 105 °C and utilizes two terminals with a lead diameter of 0.508 mm.

Feature Summary

• Unshielded molded coil design for general-purpose use
• Iron core construction supporting RF applications
• Axial leaded package for through-hole mounting

Applications

• RF circuits requiring small form factor inductors
• General-purpose filtering and signal processing
• Through-hole electronic assemblies

Procurement Notes

Verify the specific suffix variant against official API Delevan documentation, as ordering codes may indicate differences in compliance status or material composition. Confirm that the required lead length and physical dimensions match the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when an unshielded axial inductor is required for RF or general-purpose circuits. Ensure the 510 mA current rating and 0.56 µH inductance meet the circuit requirements. Consider the lack of shielding if electromagnetic interference sensitivity is a critical design factor.

Part Context

This part belongs to the API Delevan 0819 series of fixed inductors. The series offers various inductance values and tolerances in a consistent cylindrical molded package. The 0819-18K specifically denotes the 0.56 µH value with a 10% tolerance and 0.18 Ω resistance profile.

Replacement Considerations

Cross-reference with other API Delevan 0819 series variants for different inductance values. Verify compatibility with equivalent generic axial inductors by matching the 0.56 µH inductance, 0.18 Ω DCR, and 510 mA current rating specifications.
