103R-182FS

Overview

The Delevan 103R-182FS is a surface-mount RF inductor with an inductance of 1.8 µH and a tolerance of 1%. It features an unshielded design within a 103 (2525 metric) package, measuring 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. The component has a maximum DC resistance of 920 mOhms and supports a maximum DC current of 325 mA. It exhibits a minimum Q factor of 22 and a self-resolved frequency of 115 MHz. Operating temperatures range from -55°C to +125°C.

Feature Summary

• Unshielded chip construction for standard RF applications
• High precision 1% inductance tolerance
• Temperature stable operation across extended industrial ranges

Applications

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

Procurement Notes

Verify the specific manufacturer designation, as sources reference both API Delevan and generic Delevan branding. Confirm RoHS compliance status through official documentation prior to integration. Ensure the ordering suffix matches the required reel quantity specifications. Cross-reference the datasheet version to confirm electrical parameters align with current production standards.

Selection Notes

Select this component when precise 1.8 µH inductance is required without magnetic shielding interference. The unshielded design suits applications where external field coupling is manageable or desired. Evaluate the 325 mA current limit against peak load requirements. Consider the 115 MHz self-resonant frequency to ensure adequate performance at target operating frequencies.

Part Context

This part belongs to the 103R series of fixed surface-mount inductors. It utilizes a non-standard two-lead SMD configuration typical of older Delevan RF components. The series focuses on general-purpose RF applications requiring stable inductance values in compact footprints.

Replacement Considerations

Direct substitutes include the 103R-182F variant, which shares similar electrical characteristics but may differ in packaging or tolerance specifics. Verify pin compatibility and thermal performance before substitution.
