It features an unshielded construction with a ceramic core, designed for surface-mount technology (SMT) applications. The component has an inductance value of 20 nH and a tolerance of ±2%. It supports a maximum DC current of 420 mA and exhibits a maximum DC resistance of 250 mΩ. The physical package size is 0402 (1005 Metric), measuring 1.19 mm in length and 0.64 mm in width.

Fixed Inductors Feature Summary

• Utilizes ceramic core wirewound construction for RF stability
• Unshielded design suitable for compact SMT layouts
• Miniaturized form factor optimized for high-density circuit boards

Fixed Inductors Applications

• RF circuit filtering
• Impedance matching networks
• High-frequency signal processing

Fixed Inductors Procurement Notes

Verify the specific ordering suffix to ensure the correct tolerance grade and packaging configuration match the design requirements. Confirm that the unshielded nature of the component aligns with the electromagnetic interference constraints of the target application environment before finalizing procurement.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 20 nH is required for high-frequency operations. Ensure the PCB layout accounts for the lack of shielding to prevent unwanted coupling. Verify that the 420 mA current rating meets the operational demands of the specific circuit branch.

Fixed Inductors Part Context

This part belongs to the WCI1005CP series of ceramic RF inductors from INPAQ Technology. The series offers inductance values ranging from 1.0 to 120 nH in the 0402 package. These components are engineered for miniaturization and are distinct from shielded power inductors used in lower-frequency power conversion applications.

Fixed Inductors Replacement Considerations

Compatible substitutes within the same series include WCI1005CP1N0JG, WCI1005CP5N6JG, and WCI1005CP43NJG, provided the specific inductance value matches the circuit requirements. Always verify pin compatibility and electrical ratings against the original design specifications.
