Product Features
- All‑in‑one 19‑pin design: accepts UFS card, UHS‑II Micro SD, backward compatible with UHS‑I Micro SD
- Push‑push ejection operation: one‑push lock / one‑push eject, no hinge cover
- SMT surface‑mount termination; built‑in dual retention claws to prevent component offset in reflow
- Slim 1.6 mm total stacking height, optimized for thin‑profile product casing
- Stainless‑steel shielding shell: EMI shielding, anti‑twist & anti‑drop mechanical protection
- High‑temperature LCP UL94V‑0 housing, matches standard JEDEC reflow profile
- Copper‑alloy contact beam with gold‑nickel mating plating; tin‑plated SMT terminals for good solderability
- Hardware card‑detect switch included for card‑present detection signal
- Embossed tape‑and‑reel packing for automated SMT assembly lines
Product Advantages
- Single‑socket multi‑standard support: Replace two discrete sockets (UFS + Micro SD), shrink PCB footprint, lower BOM cost & layout workload.
- 1.6 mm ultra‑low profile: Fits slim portable devices where height clearance is strictly limited.
- Built‑in EMI stainless‑steel shell: Suppresses high‑speed signal interference, improves UHS‑II signal integrity for high‑speed read‑write.
- Reliable SMT manufacturability: Retention claws prevent floating/offset during reflow; reel packing compatible with high‑speed pick‑and‑place.
- Hardware card‑detect switch: Provides real‑time insertion/removal signal, reduces host‑side polling power consumption & firmware complexity.
- Wide industrial temperature range ‑40~+85℃: Suitable for consumer and outdoor/industrial embedded projects.
- Backward compatibility: Works with legacy UHS‑I Micro SD cards, avoids inventory compatibility risk for end‑products.
