What can socket do to match the speed?

UFS Card Socket

• Amphenol 19pins socket design

• Pin1~10,11,12 for UFS card use.

Fully compatible with JEDEC SO-

022A specification

• Pin11~19 for Micro SD use

• Available now through distributors

• Compatible to both micro SD and UFS card standard

• Optimized socket structure and contact shape to achieve high speed performance
