Overview
The Delevan 103R-822JS is a fixed surface-mount RF inductor with an inductance of 8.2 µH and a tolerance of 5%. It features a maximum DC resistance of 2.5 Ohms and a rated current of 195 mA. The component utilizes an unshielded construction within a nonstandard rectangular package measuring approximately 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. Designed for PCB mounting, it operates within a temperature range of -55°C to +125°C.
Feature Summary
- Unshielded wirewound construction suitable for general-purpose RF applications
- Phenolic core material providing stable inductance characteristics
- Standard two-terminal SMD/SMT termination for direct PCB integration
Applications
- RF circuit filtering
- General-purpose inductive components in electronic assemblies
- Signal processing circuits requiring specific impedance matching
Procurement Notes
Verify the exact physical dimensions against the official datasheet prior to PCB layout finalization, as the package is classified as nonstandard. Confirm that the 195 mA current rating aligns with the operational requirements of the target circuit to prevent saturation or thermal issues during procurement validation.
Selection Notes
Select this component when an unshielded 8.2 µH inductor is required for space-constrained designs where magnetic interference is manageable. Consider the 2.5 Ohm DC resistance impact on power efficiency. Ensure the operating environment remains within the specified -55°C to +125°C range for reliable performance.
Part Context
This part belongs to the Delevan 103R series of fixed RF inductors. These components are characterized by their compact rectangular form factor and phenolic core construction. The series is designed for surface-mount technology, offering a balance between electrical performance and small footprint for high-density electronic applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative manufacturers based on identical inductance, tolerance, current rating, and physical dimensions before substitution.
