0819-48H

Overview

The Delevan 0819-48H is an axial leaded RF inductor featuring a molded unshielded coil construction. It provides a nominal inductance of 10 µH with a tolerance of 3%. The component has a maximum DC resistance of 5.2 Ohms and supports a maximum DC current of 95 mA. Key electrical characteristics include a minimum Q factor of 45 and a self-resonant frequency of 47 MHz. Physical dimensions are 5.08 mm in length and 1.98 mm in diameter, designed for PCB mounting.

Feature Summary

• Molded unshielded coil design for RF applications
• Axial leaded termination style for through-hole mounting
• High Q factor performance at operating frequencies

Applications

• RF circuit filtering
• Impedance matching networks
• Tuned circuit resonance

Procurement Notes

Verify the specific tolerance suffix against ordering requirements, as documentation indicates variations between 1% and 3% for similar part numbers. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory markings may vary by production batch. Ensure the selected packaging quantity aligns with reel specifications to avoid handling discrepancies during assembly.

Selection Notes

Select this component when a 10 µH inductance value is required within the RF spectrum near 47 MHz. The 95 mA current rating dictates suitability for low-power signal paths rather than power delivery. The unshielded nature requires careful layout planning to minimize electromagnetic interference with adjacent sensitive components on the PCB.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. The series utilizes a molded construction technique to ensure mechanical stability and consistent electrical properties. Axial leads facilitate easy insertion into printed circuit boards, offering a compact footprint suitable for space-constrained electronic designs requiring reliable RF performance.

Replacement Considerations

The 0819-48F serves as a potential substitute if a tighter 1% tolerance is acceptable, though it shares identical physical dimensions and core electrical parameters. Verify that the replacement maintains the same axial lead configuration and unshielded form factor to ensure compatibility with existing board layouts.
