103R-222J

Overview

The Delevan 103R-222J is a fixed surface-mount RF inductor with a nominal inductance of 2.2 µH and a tolerance of ±5%. It features an unshielded wirewound construction on a phenolic core, housed in a non-standard 1010 package measuring 2.54 mm in length, 1.91 mm in height, and 1.27 mm in width. The component supports a maximum DC current of 310 mA and has a maximum DC resistance of 1 Ohm. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Unshielded wirewound design for specific RF applications
• Phenolic core material for stable performance
• Standard two-terminal SMD termination

Applications

• RF circuit filtering
• Impedance matching networks
• General-purpose RF signal processing

Procurement Notes

Verify the exact physical dimensions against your PCB footprint, as the 1010 package is classified as non-standard by the manufacturer. Confirm RoHS compliance status through official documentation before integration. Ensure the 310 mA current rating meets your circuit's operational requirements to prevent saturation or overheating during deployment.

Selection Notes

Select this component when an unshielded inductor is required to minimize parasitic coupling in sensitive RF layouts. The phenolic core offers a distinct electrical profile compared to ferrite alternatives. Verify that the 1 Ohm DC resistance aligns with your power loss constraints and that the 2.2 µH value fits your target frequency response specifications.

Part Context

This part belongs to Delevan’s line of fixed RF inductors designed for surface-mount technology. It utilizes a wirewound architecture on a phenolic substrate, distinguishing it from shielded power inductors in the same catalog. The 103R series provides compact solutions for high-frequency applications where magnetic shielding is not mandated by the system design.
