microSD HC typically refers to microSDHC, which stands for micro Secure Digital High Capacity. It is a type of microSD card, a small flash memory card used primarily in mobile devices such as smartphones, tablets, cameras, and other portable electronics.

Key Points about microSDHC:

  • Capacity: microSDHC cards have storage capacities ranging from 4 GB to 32 GB.
  • File System: They usually use the FAT32 file system.
  • Compatibility: microSDHC cards are compatible with devices that support the SDHC standard. They are not compatible with devices that only support the original microSD (Standard Capacity) cards unless the device explicitly supports SDHC.
  • Speed Classes: microSDHC cards come in various speed classes (Class 2, 4, 6, 10) and UHS (Ultra High Speed) classes, which indicate the minimum write speeds suitable for different applications like video recording.

Comparison with other microSD types:

Type Capacity Range File System Compatibility

microSDHC 4 GB – 32 GB FAT32 Devices supporting SDHC
microSDXC 32 GB – 2 TB exFAT Devices supporting SDXC
