Overview
The Delevan 0819-90K is a fixed axial leaded RF inductor featuring a molded unshielded ferrite core construction. It provides an inductance of 560 µH with a tolerance of ±10%. The component has a maximum DC resistance of 60 Ohms and supports a maximum DC current of 28 mA. Key electrical characteristics include a minimum Q factor of 35 and a self-resonant frequency of 5 MHz. Designed for PCB mounting, it measures 6.48 mm in length and 2.92 mm in width, suitable for high-frequency applications.
Feature Summary
- Molded unshielded ferrite core design for stable RF performance
- Axial leaded termination style for through-hole PCB integration
- High self-resonant frequency capability up to 5 MHz
Applications
- RF circuit filtering
- Impedance matching networks
- High-frequency signal processing
Procurement Notes
Verify the specific suffix (e.g., K) against official manufacturer documentation to confirm tolerance and parameter accuracy. Ensure the ordering quantity aligns with factory packaging requirements, typically supplied in reels. Confirm RoHS compliance status as indicated in the latest datasheet, noting that some legacy variants may not be compliant. Cross-reference the Mouser or DigiKey part numbers for accurate availability and lead time information before finalizing procurement plans.
Selection Notes
Select the 0819-90K when a 560 µH inductance value is required with a ±10% tolerance. Consider this component for applications needing a maximum DC current rating of 28 mA and a low DC resistance of 60 Ohms. The unshielded design requires careful layout consideration to minimize electromagnetic interference with nearby components. Verify that the 5 MHz self-resonant frequency meets the operational bandwidth requirements of the target RF circuit.
Part Context
The 0819 series represents a line of fixed RF inductors manufactured by API Delevan Inc. These components are characterized by their molded construction and axial leaded format, designed specifically for radio frequency applications. The series offers various inductance values and tolerances, catering to diverse impedance matching and filtering needs in electronic systems.
Replacement Considerations
The 0819R-90K is a confirmed substitute variant within the same product family, offering identical electrical specifications including 560 µH inductance and 60 Ohm resistance.
