- J-lead termination style for secure surface mounting
- High self-resonant frequency suitable for RF applications
Applications
- RF circuit filtering
- Impedance matching networks
- High-frequency signal processing
Procurement Notes
Verify the specific manufacturer part number against official API Delevan documentation to confirm electrical characteristics and physical dimensions. Ensure compatibility with existing PCB footprints, particularly regarding the nonstandard lead configuration. Confirm RoHS compliance status through current datasheets before integration into production workflows.
Selection Notes
Select this component when an unshielded inductor with J-leads is required for high-frequency stability. Consider the 900 mA current rating and 120 mΩ DCR limits for power handling requirements. Evaluate the 1.45 GHz self-resonant frequency against target operating bands to ensure adequate performance margins.
Part Context
This component belongs to the Delevan 103R series of fixed RF inductors. These parts are designed for surface-mount technology and utilize phenolic plastic cores. The series supports various inductance values within a compact form factor, targeting applications requiring stable inductance at radio frequencies.
Replacement Considerations
Cross-reference with other 33 nH unshielded SMD inductors featuring similar J-lead configurations. Verify that substitute components match the 120 mΩ DCR and 900 mA current ratings. Ensure replacement parts maintain comparable self-resonant frequencies and temperature coefficients.
