105R-471H

Overview

The Delevan 105R-471H is an unshielded surface-mount RF inductor with a nominal inductance of 470 nH and a tolerance of ±3%. It features a maximum DC resistance of 310 mΩ and supports a maximum DC current of 555 mA. The component exhibits a minimum Q factor of 40 and a self-resonant frequency of 220 MHz. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.65 mm in height, designed for PCB mounting.

Feature Summary

• Unshielded SMD construction for compact RF circuit integration
• High self-resonant frequency capability for signal integrity
• Standard two-terminal surface mount package

Applications

• RF filtering networks
• Impedance matching circuits
• General RF signal processing

Procurement Notes

Verify the obsolete lifecycle status before procurement planning. Confirm availability through authorized distributors or surplus channels as standard manufacturing may be discontinued. Ensure compatibility with existing PCB footprints and validate electrical parameters against current design requirements prior to ordering.

Selection Notes

Select this component for applications requiring a 470 nH unshielded inductor in a small SMD form factor. Consider the 555 mA current rating and 310 mΩ resistance for power handling needs. Compare against shielded alternatives if electromagnetic interference mitigation is required, noting that this specific part lacks magnetic shielding.

Part Context

This component belongs to the Delevan 105R series of fixed RF inductors. It shares the same inductance value (471 code) but differs from other series like the 103R or 100R in terms of shielding, current rating, and physical dimensions. It is distinct from leaded variants such as the 0925 series.
