106-472F

Overview

The Delevan 106-472F is an unshielded surface-mount RF inductor with a nominal inductance of 4.7 µH and a tolerance of ±1%. It features a maximum DC resistance of 2.3 Ohms and supports a maximum DC current of 200 mA. The component exhibits a minimum Q factor of 41 at its self-resonant frequency of 55 MHz. Its physical dimensions are 3.94 mm in length, 2.79 mm in width, and 1.91 mm in height. The device utilizes standard SMD/SMT termination types for PCB mounting.

Feature Summary

• Unshielded wirewound construction designed for radio frequency applications
• High precision inductance stability with tight manufacturing tolerances
• Compact non-standard footprint optimized for space-constrained circuit boards

Applications

• RF signal processing circuits
• Impedance matching networks
• Filtering components in communication systems

Procurement Notes

Verify the End-of-Life status before design finalization, as official documentation indicates discontinuance notifications may apply. Confirm RoHS compliance requirements against specific project standards, as this part is listed as non-compliant in some databases. Ensure supply chain availability through authorized channels due to limited stock conditions reported by distributors. Validate that the non-standard package dimensions fit the target PCB layout constraints.

Selection Notes

Select this component when high-Q performance at 55 MHz is required for RF filtering or tuning. The 200 mA current rating suits low-power signal paths rather than power handling applications. Consider the unshielded nature for placement away from sensitive analog traces to prevent interference. Verify that the 2.3 Ohm DC resistance aligns with the voltage drop limitations of the specific circuit design.
