Overview
The Delevan 0819-96K is a leaded RF inductor from the 0819 series, featuring a molded unshielded coil construction with axial termination. It provides an inductance of 1 mH with a tolerance of 10% and a maximum DC resistance of 79 Ohms. The component supports a maximum DC current of 24.5 mA and achieves a minimum Q factor of 35. Its self-resonant frequency is 3.3 MHz. Physically, it measures 5.08 mm in length and 1.98 mm in diameter, designed for PCB mount installation.
Feature Summary
- Molded unshielded coil design for RF applications
- Axial leaded termination for through-hole mounting
- High inductance stability with 10% tolerance
Applications
- RF circuit filtering
- Signal processing networks
- Impedance matching stages
Procurement Notes
Verify RoHS compliance status as documentation indicates non-compliance. Confirm axial lead dimensions and PCB hole specifications against target layout requirements. Ensure operating temperature limits align with system thermal constraints. Validate that the 24.5 mA current rating meets circuit load demands without saturation.
Selection Notes
Choose this component when high inductance is required in a compact axial form factor. The unshielded design necessitates careful placement to minimize electromagnetic interference with adjacent traces. Consider the 79 Ohm DC resistance impact on signal attenuation. The 3.3 MHz self-resonant frequency defines the upper operational limit for effective inductive behavior.
Part Context
Part of the Delevan 0819 series of fixed RF inductors. Shares physical dimensions with other variants like 0819-96F but differs in tolerance and current handling. Designed for general-purpose RF applications where space efficiency and standard axial mounting are prioritized over shielded performance.
Replacement Considerations
The 0819-96F offers identical physical dimensions and electrical parameters except for a tighter 1% tolerance instead of 10%. Verify if the stricter tolerance requirement justifies the substitution based on circuit precision needs.
