Kingstons Industrial Temperature micro SD 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 & in test & measurement situations where standard micro SD 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 & removed from host devices, & its MLC NAND allows for large amounts of data to be written to the card.
