0819-78F

Overview

The Delevan 0819-78F is a leaded RF inductor from the 0819 series, featuring an axial termination style and unshielded molded construction. It provides an inductance of 180 µH with a tight tolerance of ±1%. The component has a maximum DC resistance of 20 Ohms and supports a maximum DC current of 49 mA. Designed for PCB mounting, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Molded unshielded coil construction
• Axial leaded termination for through-hole mounting
• High precision ±1% inductance tolerance

Applications

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

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical characteristics and packaging configuration. Ensure compatibility with required PCB footprint dimensions and thermal management constraints before finalizing procurement orders.

Selection Notes

Select this component when high precision inductance is critical for RF applications requiring axial leads. Consider the 20 Ohm DC resistance limit for current handling requirements. Verify that the unshielded design does not interfere with nearby sensitive components due to potential magnetic field emission.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. These components are characterized by their molded epoxy bodies and axial leads, offering a robust solution for through-hole assembly in radio frequency environments where standard shielded packages may be unsuitable.

Replacement Considerations

The part number 0819R-78F is documented as an alias for this component. Verify functional equivalence with other 180 µH axial RF inductors only if they match the 20 Ohm DCR and 49 mA current ratings exactly.
