0819-10J

Overview

The Delevan 0819-10J is a leaded RF inductor from the 0819 series, featuring an axial termination and unshielded molded construction. It provides a nominal inductance of 270 nH with a tight tolerance of ±5%. The component supports a maximum DC current of 525 mA while maintaining a maximum DC resistance of 380 mΩ. Key electrical characteristics include a minimum Q factor of 30 and a self-resonant frequency of 440 MHz. Designed for PCB mount applications, it measures 5.08 mm in length and 1.98 mm in diameter.

Feature Summary

• Unshielded molded coil design for standard RF circuit integration
• Axial leaded termination suitable for through-hole PCB mounting
• High self-resonant frequency capability up to 440 MHz

Applications

• RF signal processing circuits
• Impedance matching networks
• Filtering applications in radio frequency systems

Procurement Notes

Verify the specific manufacturer part number against official API Delevan documentation to confirm exact electrical tolerances and physical dimensions. Ensure that the axial lead configuration and unshielded nature align with the target PCB layout and electromagnetic interference requirements. Cross-reference datasheet revisions to validate current specifications before final procurement decisions.

Selection Notes

Select this component when a precise 270 nH inductance with ±5% tolerance is required for high-frequency RF applications. Consider the 525 mA current rating and 380 mΩ resistance for power handling needs. The unshielded design requires adequate spacing on the PCB to prevent magnetic coupling with adjacent components, ensuring optimal performance at the specified 440 MHz self-resonant frequency.

Part Context

This component belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values and tolerance options, such as the 0819-10F (1% tolerance) and 0819-10H (3% tolerance), allowing designers to choose based on precision requirements. All variants share similar physical dimensions and mounting styles, facilitating consistent board design across different circuit specifications.

Replacement Considerations

For equivalent inductance and tolerance, consider the 0819-10F or 0819-10H from the same manufacturer. These parts share identical physical dimensions and basic electrical profiles but offer tighter tolerances. Verify compatibility with existing circuit designs before substitution.
