0819-62G

Overview

The Delevan 0819-62G is a fixed axial leaded RF inductor featuring a molded unshielded coil design. It provides an inductance of 39 µH with a tight tolerance of ±2%. The component exhibits a maximum DC resistance of 6.8 ohms and supports a maximum DC current of 83.5 mA. Key electrical characteristics include a minimum Q factor of 45 at 2.5 MHz and a self-resonant frequency of 15 MHz. Designed for through-hole PCB mounting, it utilizes standard terminals and ferrite core technology.

Feature Summary

• Molded unshielded construction for compact axial integration
• High precision ±2% inductance tolerance
• Ferrite core material optimized for RF performance

Applications

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

Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan and Delevan. Confirm the package type is axial leaded and the tolerance is 2%. Ensure the datasheet matches the 39 µH value and 6.8 ohm DCR specifications before finalizing procurement to avoid substitution errors with similar series parts.

Selection Notes

Select this component when a precise 39 µH inductance is required for RF applications with strict tolerance limits. The unshielded design necessitates careful layout consideration to prevent magnetic coupling with adjacent components. Verify that the 83.5 mA current rating meets the circuit's operational requirements and that the 15 MHz self-resonant frequency aligns with the target signal band.

Part Context

This part belongs to the Delevan 0819 series of RF inductors. The series offers various inductance values with different suffix codes indicating tolerance and resistance characteristics. These components are designed for general-purpose RF applications requiring reliable performance in a small axial footprint.

Replacement Considerations

Direct substitutes within the same series include 0819-60F (33 µH) or 0819-62G variants if available. Cross-reference exact inductance, tolerance, and DCR values to ensure functional equivalence in the specific RF circuit application.
