The component exhibits a minimum Q factor of 30 and a self-resonant frequency of 52 MHz. It is classified as an unshielded fixed inductor designed for SMT installation.
Feature Summary
- Surface-mount construction for automated PCB assembly
- Unshielded wirewound design suitable for RF applications
- Established reliability classification
Applications
- RF circuit filtering
- Impedance matching networks
- General-purpose RF signal processing
Procurement Notes
Verify the specific ordering suffix and package variant to ensure compatibility with the target PCB footprint. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary. Validate that the 175 mA current rating meets the operational requirements of the intended circuit design before finalizing procurement.
Selection Notes
Select this component when a 4.7 µH value with tight 3% tolerance is required for high-frequency applications. Ensure the 3.1 Ohm DC resistance aligns with power loss constraints. The unshielded nature requires consideration of magnetic interference in dense layouts. Verify that the 52 MHz self-resonant frequency covers the operating bandwidth.
Part Context
This part belongs to the Delevan RF inductor portfolio, characterized by established reliability standards. It serves as a passive component for radio frequency systems where precise inductance values are critical. The series is designed for integration into communication and signal processing hardware requiring stable performance at specific frequencies.
Replacement Considerations
Cross-reference with other Delevan SMD RF inductors offering identical 4.7 µH inductance and compatible physical dimensions. Verify that substitute components maintain the same 3.1 Ohm maximum DC resistance and 175 mA current handling capabilities to ensure electrical equivalence.
