microSDの世代とコンボソケットガイド

When the standard microSD socket is not enough

The standard microSD guide covers the single-row socket. This page covers the rest of the family: second-row microSD 4.0 (UHS-II), PCIe-based microSD Express (SD 7.0 & 8.0), and the microSD + USB / microSD 4.0 + UFS combo sockets that let one slot accept two card types.

microSD 4.0 (UHS-II)

Listed models add the UHS-II contact row at 0.8mm / 0.9mm pitch, with profile heights of 1.30mm, 1.50mm, 1.63mm and 1.67mm and a 3000-insertion durability rating. Choose it when your host controller exposes UHS-II lanes.

microSD Express (SD 7.0 / 8.0)

The microSD Express series carries the PCIe/NVMe generation in the micro form factor: listed models use 0.90mm pitch at 2.25mm, 2.27mm and 2.525mm heights, with C5210 copper-alloy contacts and stainless (SUS304) shells. Full-size equivalents are in the SD Express guide.

Combo sockets: two cards, one slot

microSD + USB models accept a microSD card or a USB plug in the same opening — useful on panel equipment where one cutout must serve both. The microSD 4.0 + UFS socket accepts UFS removable cards alongside microSD. Both use LCP housings with phosphor-bronze contacts on listed models.
