0819-36J

Overview

The Delevan 0819-36J is a leaded RF inductor from the 0819 series, featuring an axial termination style and unshielded molded construction. It provides an inductance of 3.3 µH with a tight tolerance of ±5%. The component supports a maximum DC current of 198 mA and has a maximum DC resistance of 1.2 Ohms. Key electrical characteristics include a minimum Q factor of 45 and a self-resonant frequency of 100 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 RF circuit integration
• Axial leaded termination for standard PCB mounting
• High precision inductance tolerance for stable signal performance

Applications

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

Procurement Notes

Verify the specific tolerance suffix (J for 5%) against schematic requirements, as the 0819 series includes variants with different tolerances such as F (1%). Confirm that the 198 mA current rating aligns with the target circuit's operational limits. Ensure the unshielded package type does not interfere with adjacent high-frequency traces due to potential magnetic field radiation.

Selection Notes

Select this model when a precise 3.3 µH value is required with strict 5% tolerance constraints. The 100 MHz self-resonant frequency defines the upper operational limit for effective inductive behavior. Compare against higher current alternatives if the application exceeds 198 mA, or consider shielded variants if electromagnetic interference mitigation is critical for the system layout.

Part Context

This component belongs to the Delevan 0819 series of fixed RF inductors. The series utilizes a molded unshielded construction technique to ensure consistent electrical properties across various radio frequency applications. The axial lead form factor allows for straightforward insertion into printed circuit boards, supporting both through-hole assembly processes and manual prototyping workflows.

Replacement Considerations

The 0819-36F serves as a direct substitute within the same series, offering identical physical dimensions and electrical parameters except for a tighter 1% inductance tolerance instead of 5%. Verify that the increased precision requirement of the F variant is compatible with the design budget and manufacturing capabilities before substitution.
