- Unshielded construction for minimal magnetic interference
- Phenolic core material for stable performance
- Surface-mount design for PCB integration
Applications
- RF circuit filtering
- Impedance matching networks
- General-purpose RF signal processing
Procurement Notes
Verify the specific manufacturer part number against official API Delevan documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with existing PCB footprints and thermal management requirements before procurement. Cross-reference datasheets for any recent product change notices or RoHS compliance updates.
Selection Notes
Select this component when an unshielded inductor with 8.2 µH inductance is required for RF applications. Consider the 195 mA current rating and 2.5 Ohm DC resistance for power handling limits. Verify that the non-standard package dimensions fit the designated board space and that the phenolic core meets environmental operating conditions.
Part Context
This component belongs to the 103R series of fixed surface-mount inductors manufactured by API Delevan. The series is designed for radio frequency applications requiring compact, unshielded inductive elements. The 103R-822J variant specifically provides 8.2 µH inductance with standard tolerance levels suitable for general RF circuitry.
Replacement Considerations
Direct substitutes include other 8.2 µH unshielded SMD inductors from compatible manufacturers, provided they match the 195 mA current rating and 2.5 Ohm DCR. Verify package footprint compatibility and thermal characteristics. No specific public substitute part numbers are confirmed in the source data.
