Overview
The Delevan 106-471H is a fixed surface-mount RF inductor with an inductance of 470 nH and a tolerance of 3%. It features an unshielded design suitable for nonstandard footprints. The component supports a maximum DC current of 450 mA and has a maximum DC resistance of 500 mOhms. Key electrical parameters include a minimum Q factor of 45 and a self-resonant frequency of 180 MHz. The physical dimensions are 3.94 mm in length, 2.79 mm in width, and 1.91 mm in height.
Feature Summary
- Unshielded construction for specific layout requirements
- High self-resonant frequency operation at 180 MHz
- Standard two-lead surface mount termination
Applications
- RF circuit filtering
- Impedance matching networks
- General purpose SMD RF applications
Procurement Notes
Verify the RoHS compliance status carefully, as sources indicate conflicting information regarding environmental certification. Confirm the availability of the unshielded variant against shielded alternatives like the SP1210R series if shielding is required. Ensure the nonstandard footprint matches the PCB design constraints before ordering.
Selection Notes
Select this component when an unshielded inductor is necessary to prevent magnetic interference with nearby components. The 470 nH value and 180 MHz self-resonant frequency make it suitable for higher frequency RF applications. Consider the 450 mA current rating to ensure it meets the circuit's operational demands without saturation.
Part Context
This part belongs to the Delevan fixed inductor family, specifically designed for surface mount technology. It is distinct from shielded power inductors in the same brand lineup, such as the SP1210R series, which offer different current ratings and shielding characteristics. The 106 series focuses on RF performance metrics.
Replacement Considerations
The 106-471F is a similar unshielded variant but differs in tolerance (1% vs 3%) and DCR (0.5 Ohm). Shielded alternatives include the SP1210R-471H and 1331R-471H, which provide higher current handling and magnetic containment but require different footprint considerations.
