Procurement Notes
Verify the specific datasheet version when sourcing, as technical documentation may be updated by Wurth Elektronik. Confirm that the received components match the AEC-Q200 qualification status required for your application. Ensure storage conditions adhere to the manufacturer's guidelines to maintain solderability and electrical integrity prior to assembly.
Selection Notes
Select this component when a small form factor is critical for internal device placement. The AEC-Q200 rating makes it suitable for automotive electronics requiring high reliability. Consider the 7mm length constraint during PCB layout planning to ensure adequate clearance and proper grounding plane design for optimal radiation efficiency.
Part Context
This part belongs to the WE-MCA series of multilayer chip antennas from Würth Elektronik. These components are engineered for general electronic equipment and mobile devices. The series offers various sizes and frequencies, with this specific model targeting the ISM band applications requiring robust surface mount capabilities.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires independent verification of impedance matching, physical dimensions, and radiation patterns against the original design requirements.
