Overview
The Delevan 103-822F is an unshielded surface-mount RF inductor with a nominal inductance of 8.2 uH and a tolerance of 1%. It features a maximum DC resistance of 2.5 Ohms and supports a maximum DC current of 195 mA. The component has a minimum Q factor of 22 and a self-resonant frequency of 50 MHz. It utilizes standard SMD/SMT terminals for PCB mounting within the 103/R series.
Feature Summary
- Unshielded construction suitable for general RF applications
- High precision 1% inductance tolerance
- Standard SMD/SMT termination style
Applications
- RF circuit design
- PCB mount implementations
Procurement Notes
Verify the specific RoHS compliance status, as source data indicates conflicting information regarding environmental standards. Confirm the exact package dimensions and terminal specifications against the official datasheet to ensure compatibility with automated placement equipment and target PCB footprints prior to ordering.
Selection Notes
Select this component when a precise 8.2 uH value is required with tight tolerance constraints. Consider the 195 mA current limit and 2.5 Ohm resistance for power dissipation calculations. Ensure the 50 MHz self-resonant frequency aligns with the operational bandwidth requirements of the intended RF application.
Part Context
This part belongs to the 103/R series of fixed RF inductors manufactured by Delevan. It is designed for surface-mount technology applications requiring stable inductance values. The product falls under the broader category of passive components, specifically inductors, chokes, and coils used in electronic signal processing.
Replacement Considerations
The 103-682FS serves as a related alternative within the same series, offering similar physical characteristics but differing in inductance value (6.8 uH) and resistance parameters.
