The IUDD362 industrial-grade microSD cards implement SLC NAND Flash for higher reliability and provide transfer rates up to 30/25MB per second. They also feature low power consumption, high reliability, and compatibility across diverse removable storage applications that require security, convenience, performance, and capacity. With a wide temperature tolerance range of -40°C to 85°C, the IUDD362 can operate normally even in harsh environments. All ADATA industrial-grade SD/microSD cards support a range of technologies, including error correcting code (ECC) to ensure the integrity of data transfers by automatically detecting and correcting errors, and wear leveling technology, which ensures data is written evenly across all sectors to extend the life of the memory card.
