744761112A

Fixed Inductors Overview

The Würth Elektronik 744761112A is a surface-mount RF inductor from the WE-KI series, designed for high-frequency applications. It features a wirewound construction with a ceramic core and an unshielded drum core design. The component offers an inductance of 12 nH with a tolerance of ±5%. It supports a maximum DC current of 700 mA and has a maximum DC resistance of 130 mΩ. Housed in a compact 0603 (1608 metric) package, it is AEC-Q200 qualified for automotive reliability.

Fixed Inductors Feature Summary

• Wirewound construction on a ceramic core for stable RF performance
• AEC-Q200 qualification ensuring automotive-grade reliability
• Unshielded drum core design suitable for high-frequency circuits

Fixed Inductors Applications

• RF matching networks in wireless communication devices
• Impedance matching stages in mobile phone antenna systems
• High-frequency filtering in automotive electronics

Fixed Inductors Procurement Notes

Verify the specific datasheet revision and AEC-Q200 certification status directly with the manufacturer before integration. Confirm that the 0603 package dimensions align with your PCB footprint requirements. Ensure that the 700 mA current rating meets the operational demands of your circuit to prevent saturation or thermal issues during peak loads.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 12 nH is required for RF tuning. The unshielded design may necessitate careful layout planning to minimize electromagnetic interference with adjacent traces. Consider the 0603 size constraint if space is limited, and verify that the ceramic core material suits the operating temperature range of the target application.

Fixed Inductors Part Context

This part belongs to the WE-KI series of SMT wire-wound ceramic inductors by Würth Elektronik. These components are engineered for radio frequency applications where small form factors and high Q-factors are critical. The series provides various inductance values within the 0603 package, catering to diverse impedance matching needs in modern electronic designs.

Fixed Inductors Replacement Considerations

Check for direct substitutes within the same WE-KI series offering identical 12 nH specifications. Verify that any alternative maintains the same 0603 footprint and AEC-Q200 qualification if automotive use is intended. Ensure comparable DC resistance and current ratings to avoid performance degradation in the RF circuit.
