Frequently Asked Questions

Q: What type of memory card is compatible with the CT125018530E7?

A: The CT125018530E7 is compatible with standard Micro SD, Micro SDHC, and Micro SDXC memory cards, supporting common SDIO applications.

Q: What does “H1.85” mean in the product description?

A: H1.85 refers to the connector height of 1.85mm above the PCB surface, making it suitable for ultra-thin and compact electronic devices.

Q: Is the CT125018530E7 suitable for automated SMT assembly?

A: Yes, the connector is supplied in tape and reel packaging and designed for standard surface-mount technology (SMT) assembly processes.

Q: What is the difference between push-push and push-pull card sockets?

A: A push-push socket uses a spring-loaded mechanism where the card is inserted by pushing once and ejected by pushing again. A push-pull socket requires the user to pull the card out directly. The CT125018530E7 uses the push-push mechanism for easier card removal.
