103R-560K

Overview

The Delevan 103R-560K is a fixed surface-mount RF inductor with a nominal inductance of 0.056 µH (56 nH) and a tolerance of 10%. It features a maximum DC resistance of 0.17 Ω and a rated current of 760 mA. The component utilizes an unshielded chip construction with a phenolic core, housed in a nonstandard 2-lead SMD package measuring 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. It operates within a temperature range of -55 °C to 125 °C.

Feature Summary

• Unshielded chip design for general-purpose RF applications
• Phenolic core material construction
• Surface-mount form factor with two terminals

Applications

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

Procurement Notes

Verify the specific suffix 'K' confirms the 10% tolerance and 0.17 Ω DCR specifications. Confirm the package dimensions match the required board layout, as this is a nonstandard footprint. Ensure the operating environment stays within the -55 °C to 125 °C range to maintain performance integrity.

Selection Notes

Select this component when a low-inductance, unshielded RF solution is required. The 760 mA current rating suits moderate power applications. Consider the phenolic core material properties for thermal stability. Verify that the lack of shielding does not interfere with nearby sensitive components in the final assembly.

Part Context

This part belongs to the API Delevan 103R series of fixed inductors. The series includes variants with different inductance values, such as the 103R-820KS. These components are designed for high-frequency applications where compact size and specific electrical characteristics are prioritized over magnetic shielding.

Replacement Considerations

Cross-reference with other 56 nH SMD inductors from API Delevan or compatible manufacturers. Ensure substitute parts match the 0.17 Ω DCR and 760 mA current limits. Verify physical footprint compatibility due to the nonstandard package dimensions.
