Yamaichi Electronics has announced a series of UHSII SD card readers. UHS-II is the second version of the Ultra High Speed (UHS) bus classification for SD Flash memory cards. The FPS017T series extends the SD card reader family and also represents a practical extension to the High Speed product line, for which Yamaichi offers a variety of internal and I/O connectors.

The FPS017T series was developed for 4th gen SD cards and therefore meets UHS-II requirements. That means that instead of the usual nine contacts, this reader now has 17 contacts to support transmission rates of up to 312Mb/s.

Yamaichi offers these next-gen card readers in top and reverse mount versions (FPS017T-1000-x or FPS017T-2000-x). A closed metal housing with four tabs for connection to the circuit board ensures good EMC shielding. The FPS017T series offers a convenient push/push mechanism, that is, the card engages when pressed once. When it is pressed again, the mechanism releases it and the card can safely be removed. A card brake provides the definitive ejection of the card.

A card presence switch ensures that the read/write process only starts or stops when the card is completely inserted or removed. This guarantees data transmission and prevents data loss.

Depending on customer requirements and the application, contacts are available in different gold plating variants – from Gold flash to 0.76µm.

The card readers are delivered in trays or tape-and-reel packaging as needed, offering the greatest possible flexibility in assembly.

Yamaichi Electronics offers not only these components, but also many other card connectors for all available Flash and SIM card types with different form factors, such as Micro-SIM, microSD, MMCmicro, CompactFlash and multi-card versions. An extensive line of high-speed products includes various board-to-cable connectors, high-speed FPC, floating board-to-board connectors and I/O interfaces for high transmission rates at 100Ω differential impedance.
