103R-221J

Overview

The Delevan 103R-221J is a fixed surface-mount RF inductor with an inductance of 220 nH and a tolerance of ±5%. It features a maximum DC resistance of 220 mΩ and a rated current of 665 mA. The component utilizes a ferrite core and operates within a temperature range of -55°C to 125°C. It has a self-resonant frequency of 450 MHz and a Q factor of 25 at 25 MHz. The package is a non-standard SMD form factor.

Feature Summary

• Non-shielded construction for minimal magnetic interference
• Ferrite core material for stable RF performance
• Surface mount design for automated assembly

Applications

• RF circuit filtering
• Impedance matching networks
• High-frequency signal processing

Procurement Notes

Verify the specific manufacturer designation, as API Delevan and Delevan are referenced interchangeably. Confirm RoHS compliance status through official documentation, as sources vary. Ensure the non-standard package dimensions match the target PCB footprint before finalizing procurement orders.

Selection Notes

Select this component for applications requiring low inductance values in the nano-Henry range. Consider the 665 mA current rating against peak load requirements. The unshielded nature requires careful layout planning to prevent coupling with nearby sensitive traces or components.

Part Context

This part belongs to the Delevan family of fixed RF inductors designed for high-frequency electronics. It serves as a passive component for tuning and filtering signals in wireless communication devices and RF transceivers where precise inductance is critical.
