0819-84G

Overview

The Delevan 0819-84G is a leaded RF inductor from the 0819 series, featuring an unshielded molded coil design. It offers an inductance of 330 µH with a tight tolerance of 2%. The component has a maximum DC resistance of 40.5 Ohms and supports a maximum DC current of 34 mA. Key electrical characteristics include a minimum Q factor of 35 at 790 kHz and a self-resonant frequency of 6.2 MHz. Designed for PCB mounting, it operates within a temperature range of -55°C to 105°C.

Feature Summary

• Unshielded molded construction for RF applications
• High precision 2% inductance tolerance
• Axial leaded package for through-hole mounting

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF inductance requirements

Procurement Notes

Verify RoHS compliance status as sources indicate non-compliance. Confirm axial lead dimensions and molding material specifications against schematic requirements. Ensure operating temperature range meets environmental constraints. Cross-reference manufacturer part number with distributor codes to avoid ordering errors.

Selection Notes

Select this component when high stability and precise inductance are required for RF circuits. The unshielded design necessitates careful layout to minimize interference. Consider the low current rating and high DC resistance for power handling limitations. Verify that the self-resonant frequency aligns with the target signal bandwidth.

Part Context

Part of the Delevan 0819 series of fixed RF inductors. This series specializes in molded, unshielded coils for general-purpose RF applications. The 0819-84G represents a higher inductance variant compared to lower-value models in the same family, suitable for specific frequency band operations.

Replacement Considerations

Direct substitute: 0819R-84G. Verify if the 'R' suffix denotes a specific reel packaging or minor specification variation. Ensure functional equivalence in inductance, tolerance, and current ratings before substitution.
