0819-46J

Overview

The Delevan 0819-46J is an axial leaded RF inductor with a nominal inductance of 8.2 µH and a tolerance of ±5%. It features a molded unshielded construction with a maximum DC resistance of 4.4 Ohms and a maximum DC current rating of 104 mA. The component has a minimum Q factor of 45 and a self-resonant frequency of 30 MHz. Physical dimensions include a length of 5.08 mm and a diameter of 1.98 mm, designed for PCB mount applications.

Feature Summary

• Molded unshielded coil construction for general RF use
• Axial leaded termination style for through-hole mounting
• Standard terminal configuration compatible with PCB assembly

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF signal processing

Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan and Delevan. Confirm RoHS compliance status, as documentation indicates non-compliance in some records. Ensure the ordering suffix matches the required reel quantity if applicable. Cross-reference the datasheet to confirm the exact DC resistance and current ratings for your specific design requirements before finalizing procurement.

Selection Notes

Select this component when an 8.2 µH inductance with ±5% tolerance is required for RF applications. Consider the 104 mA current limit and 4.4 Ohm DC resistance for power handling. The axial package suits through-hole designs. Verify that the 30 MHz self-resonant frequency aligns with the operating bandwidth. Check environmental compliance needs against the non-RoHS data found in some listings.

Part Context

The 0819 series represents a line of molded, unshielded RF inductors from Delevan (API Delevan). These components are characterized by their axial leads and standard PCB mount style. The 0819-46J specifically provides 8.2 µH inductance, fitting within the broader family of fixed inductors used for radio frequency signal conditioning and circuit stabilization.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. When seeking alternatives, match the 8.2 µH inductance, ±5% tolerance, 104 mA current rating, and axial package dimensions. Verify that any replacement maintains similar Q factor and self-resonant frequency characteristics for RF compatibility.
