Feature Summary

• Unshielded construction suitable for general-purpose RF applications
• Surface-mount design for automated PCB assembly
• Standard two-terminal configuration

Applications

• RF circuit filtering
• Signal processing networks
• General-purpose inductive components

Procurement Notes

Verify the specific manufacturer datasheet to confirm electrical parameters and physical dimensions prior to integration. Ensure compatibility with surface-mount reflow or wave soldering processes defined by the manufacturer's specifications. Cross-reference the part number with official API Delevan documentation to validate current production status and availability constraints.

Selection Notes

Select this component when a 10 µH inductance value is required for RF circuits with low current demands up to 165 mA. Consider the unshielded nature of the device regarding potential electromagnetic interference coupling in dense layouts. Evaluate the 3.45 Ω DC resistance impact on power loss within the target application circuit against alternative shielded options if isolation is critical.

Part Context

This part belongs to the 103/R series of fixed inductors manufactured by API Delevan. The series offers various inductance values tailored for radio frequency applications. The 103R-103KS specifically addresses needs for moderate inductance in compact surface-mount form factors, distinguishing it from higher-current power chokes or lower-inductance high-frequency variants within the broader product line.

Replacement Considerations

Direct substitutes include other 10 µH ±10% unshielded SMD inductors with comparable current ratings (approx. 165 mA) and DC resistance (≤3.45 Ω). Verify footprint compatibility (2.54 x 2.54 mm) and thermal characteristics before substitution.
