Description
A 1.00 mm pitch, 29-pin SD 8.0 memory card connector in a top-mount SMT, push-push design. It accepts SD 8.0 / 7.0 / 4.0 / 3.0 cards with a peak transfer rate of about 4 GB/s — built for laptops, readers, docking stations and cameras where a press-to-eject, one-handed card swap is part of the product. Engineer reply within 1 working day · RoHS compliant · Custom options available A push-push connector adds an ejector mechanism, and every card swap is a direct vote on it. A crisp eject, no jamming and no accidental pop-out matter more to the product's reputation than the connector price. These are the four problems this 3.58 mm part is built to keep off your desk. The ejector is the part of a push-push socket that fails first. A reliable cam-and-spring design keeps every press stroke consistent for a crisp, clean eject across 10,000 insertion cycles. Push-push means press to lock, press again to eject. The card pops out with clear tactile feedback — more intuitive than a push-pull slot you have to pry out. Gold-plated terminals (≥0.025 µm) hold contact resistance to ≤30 mΩ with tight coplanarity control, keeping SD 8.0 signals stable through humidity and thermal cycling. An LCP insulator takes lead-free reflow without deformation; the stainless-steel shell keeps the frame flat; terminals are coplanarity-controlled to ±0.05 mm for stable placement. A datasheet lists values. A specification explains what each value controls. Final tolerances, plating thickness and acceptance criteria are confirmed on the 2D drawing and datasheet. Push-push failures are rarely dramatic. They are a press that gets stiffer, a card that reads intermittently in a hot car, a card that stops popping out. Same SD card, same 4 GB/s interface — the SD 8.0 family offers four height and mechanism combinations. Most sourcing mistakes are not a bad connector; they are the right connector in the wrong stack-up. A push-push socket's press-to-eject matters most where users swap cards one-handed, without looking at the device. Push-push has a built-in ejector: press once to lock, press again to eject — intuitive for consumer-facing devices. Push-pull has no ejector; the card is held by the shell and pulled straight out — fewer parts, nothing to jam, better for fixed and industrial use. In the SD 8.0 family, push-pull is available at 2.94 mm and 2.98 mm, and push-push at 2.98 mm and 3.58 mm. SD 8.0 uses a PCIe 4.0 interface with a peak transfer rate of about 4 GB/s — far above the 104 MB/s of SD 3.0 — ideal for 4K/8K video and high-speed burst photography. SD 8.0 sockets are backward compatible with SD 7.0 / 4.0 / 3.0 cards; the card opening is the same, but the pin definition and signal-integrity requirements are higher. This part is rated for 10,000 insertion cycles, and the cam-and-spring ejector is life-tested for consistent stroke and feel. If your application cycles more often, tell us in the requirement and we will evaluate a reinforced design. Send the part number and, if possible, the drawing. We compare pad layout, height, pitch and retention, then confirm whether the replacement is truly drop-in or needs a layout change. Sampling follows the review. Samples are free, sampling takes 7 days, and volume production is 7–15 days. MOQ and lead time are confirmed with the quotation, based on plating and packaging options. Zero-MOQ trial runs are available. Tell us the product thickness, card type, annual volume and the part you are replacing (if any). An engineer replies within one working day with the right model, the drawing you need, and what we would change in your layout — if anything.
