Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct packaging configuration. Confirm that the selected variant matches the required tape and reel specifications for automated assembly processes. Cross-reference the component marking with official documentation to prevent counterfeit substitution during sourcing.

Selection Notes

Select this component when a low-profile SMD antenna is required for 2.4GHz ISM band operations. Ensure the PCB layout accommodates the specified ground plane requirements for optimal radiation efficiency. Consider the physical footprint constraints relative to the 7mm length and 1.2mm height dimensions during mechanical design.
