103R-222JS

Overview

The Delevan 103R-222JS is a surface-mount RF inductor with an inductance of 2.2 µH and a tolerance of ±5%. It features a non-shielded construction using a phenolic core material, housed in a 1010 (2.54 mm x 2.54 mm) package with a height of 1.91 mm. 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

• Non-shielded SMD design for general-purpose RF applications
• Phenolic core material construction
• Standard two-terminal surface mount configuration

Applications

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

Procurement Notes

Verify the specific manufacturer designation, as sources attribute this part to both API Delevan and Delevan. Confirm RoHS compliance status through official documentation before integration. Ensure the non-shielded characteristic aligns with EMI requirements for the target PCB layout.

Selection Notes

Select this component for low-power RF circuits requiring a 2.2 µH value in a compact 1010 footprint. The non-shielded nature requires careful placement to minimize coupling. Verify that the 310 mA current rating meets the operational load without saturation or excessive thermal rise.

Part Context

This part belongs to the 103R series of fixed RF inductors from Delevan. These components are designed for surface-mount technology and utilize phenolic cores. The series offers various inductance values optimized for radio frequency applications where shielding is not strictly required.

Replacement Considerations

Cross-reference with other 1010 package RF inductors having 2.2 µH nominal value and similar current ratings. Verify pin compatibility and electrical parameters such as DCR and Q factor before substitution.
