Micro SD card socket
Model: WK-3039-40
Applications

Description
WK-3039-40 is a high-performance, ultra-thin Micro SD card socket. This product features a self-popping structure with a height of only 1.28mm, significantly saving PCB layout space. It is particularly suitable for portable electronic devices such as smartphones, tablet computers, and digital cameras. Its terminals are made of phosphor bronze and plated with gold, while the housing is made of stainless steel, ensuring excellent electrical connection stability, corrosion resistance, and a mechanical lifespan of up to 5000 cycles. It supports 12V voltage and hot-swapping functionality, complies with RoHS environmental standards, and is an ideal choice for embedded storage applications.
Features
- Self-popping structure, where pressing achieves insertion locking and popping, making operation convenient.
- With an ultra-thin design, the overall height is only 1.28mm, making it suitable for portable devices with limited space.
- Hot-swappable, supporting safe insertion and removal of memory cards while the device is running.
- It can withstand at least 5000 insertion and extraction cycles.
- Compliant with the standard interface specification of Micro SD card, with 8Pin definition
- Resistant to corrosion, with a stainless steel shell made of SUS301 and gold-plated terminals, ensuring stable connection
