0819-88K

Overview

The Delevan 0819-88K is a leaded RF inductor featuring a molded unshielded coil design with a ferrite core. It provides an inductance of 470 µH with a tolerance of ±10%. The component supports a maximum DC current of 31.5 mA and has a maximum DC resistance of 48 Ohms. It exhibits a minimum Q factor of 35 and a self-resonant frequency of 5.4 MHz. The axial leads facilitate PCB mounting, and the unit operates within a temperature range of -55°C to +105°C.

Feature Summary

• Molded unshielded construction utilizing a ferrite core for stable RF performance
• Axial lead configuration designed for through-hole PCB mounting applications
• High inductance value suitable for specific radio frequency filtering requirements

Applications

• Radio frequency signal processing circuits
• RF filtering networks requiring high inductance
• Leaded component integration in specialized electronic assemblies

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm lead length specifications against mechanical constraints. Validate thermal management capabilities given the low current rating. Ensure supplier sources authentic API Delevan components to guarantee electrical parameter accuracy. Cross-reference datasheet revisions for any updates to physical dimensions or material composition before finalizing procurement.

Selection Notes

Select this component when a high inductance value is required in a leaded format. The unshielded design necessitates careful layout planning to minimize electromagnetic interference with adjacent traces. Evaluate the 31.5 mA current limit against circuit load requirements. Consider the self-resonant frequency to ensure operation remains below the resonance point for intended inductive behavior.

Part Context

This part belongs to the Delevan 0819 series of fixed inductors. The series offers various inductance values and tolerances using similar molded unshielded coil technology. These components are engineered for general-purpose RF applications where leaded termination is preferred over surface mount alternatives. The series maintains consistent physical dimensions across different electrical variants.

Replacement Considerations

Direct substitutes include other Delevan 0819 series variants with matching 470 µH inductance and axial lead form factors. Verify that alternative parts maintain identical 48 Ohm DC resistance and 5.4 MHz self-resonant frequency characteristics to ensure circuit compatibility.
