105-221F

Overview

The Delevan 105-221F is a fixed surface-mount RF inductor with an inductance of 220 nH and a tolerance of ±1%. It features a maximum DC resistance of 210 mΩ and a current rating of 675 mA. The component operates within a temperature range of -55°C to +125°C. It utilizes a nonstandard two-lead SMD package, specifically the 1010 footprint, with epoxy encapsulation and iron core material.

Feature Summary

• Unshielded construction for minimal magnetic interference
• High precision ±1% inductance tolerance
• Epoxy encapsulated design for environmental protection
• Iron core material optimized for RF applications

Applications

• RF circuit filtering
• Compact electronic signal processing
• General purpose RF inductor tasks

Procurement Notes

Verify RoHS compliance status as sources indicate lead content or non-compliance. Confirm the specific manufacturer designation, as API Delevan and Delevan are referenced interchangeably. Ensure the 1010 package footprint matches the target PCB layout requirements before procurement.

Selection Notes

Select this component for applications requiring precise 220 nH inductance with tight tolerance. Consider the 675 mA current limit and 210 mΩ DC resistance for power handling. The unshielded nature requires careful placement to avoid magnetic coupling issues in dense layouts.

Part Context

This part belongs to the fixed inductor category within the passive components family. It is designed for surface-mount technology (SMT) assembly. The 105 series indicates a specific form factor and performance class tailored for radio frequency environments.

Replacement Considerations

The 105R-221F is identified as a related variant with identical electrical specifications. Verify pin compatibility and package dimensions when substituting.
