0819-68J

Overview

The Delevan 0819-68J is a leaded RF inductor from the 0819 series, featuring an axial termination style and unshielded molded construction. It provides an inductance of 68 µH with a tolerance of ±5%. The component has a maximum DC current rating of 64 mA and a maximum DC resistance of 11.5 Ohms. It exhibits a minimum Q factor of 45 and a self-resonant frequency of 11.5 MHz. Designed for PCB mounting, it measures 5.08 mm in length and 1.98 mm in diameter.

Feature Summary

• Unshielded molded coil design for RF applications
• Axial leaded termination for through-hole PCB mounting
• High self-resonant frequency capability

Applications

• RF circuit filtering
• Impedance matching networks
• Signal processing circuits

Procurement Notes

Verify the specific manufacturer designation, as sources indicate API Delevan Inc. or Delevan. Confirm RoHS compliance status, as documentation varies between compliant and non-compliant listings. Ensure the ordering suffix matches the required tolerance and packaging format for production integration.

Selection Notes

Select this component when a high-inductance value is required in a leaded form factor. The 68 µH value suits lower frequency RF tuning compared to nanohenry variants. Consider the 64 mA current limit and 11.5 Ohm resistance for power handling requirements in the target circuit design.

Part Context

This part belongs to the Delevan 0819 series of fixed inductors. The series offers various inductance values ranging from nanohenries to microhenries in both leaded and surface mount packages. The 0819-68J specifically addresses needs for higher inductance in axial configurations.

Replacement Considerations

Cross-reference with other 68 µH axial RF inductors if availability is constrained. Verify that substitute components match the 11.5 Ohm DCR and 64 mA saturation current limits to maintain circuit performance.
