Kingston’s Industrial Temperature microSD UHS-I has an operating temperature rating of -40°C to 85°C, making it suitable for harsh environments. Its high operating temperature rating means it stands up to extreme heat in the desert and in test and measurement situations where standard microSD cards may fail, while its low operating temperature rating allows for use in below freezing weather, where equipment may be left outside for extended periods of time. Its high insertion rating is ideal for applications in which the card will be frequently accessed and removed from host devices, and its MLC NAND allows for large amounts of data to be written to the card. Kingston tests these cards extensively during pre-production and new build qualifications. Cards must pass thermal cycle testing, with interval testing at various extreme temperatures; vigorous temperature humidity bias, comprised of several hundred hours of testing to ensure durability at different humidity levels; and wide temp chamber testing. In addition, these cards are tested to be waterproof, temperature proof, shock/vibration proof and X-ray proof. So you can rest assured your photos, videos and other important files will be protected. With UHS-I Speed Class U1 speeds up to 90MB/s read and 45MB/s write, the card is ideal for applications requiring greater bandwidth when recording large datasets. Higher sustained write speeds ensure data integrity by reducing transmission stutter, and the card also offers faster upload times when transferring files to a PC. The smallest available SD card, it is the standard expandable storage option for many GPS, tablets, smartphones and industrial devices and, with the included adapter, can be used in standard size SDHC/SDXC host devices.
