Utility SD

Delkin’s Utility SD cards are compliant with the SD 3.0 standard for performance and built to industrial standards with a controlled BOM and managed life cycle. Utility SD cards are rated for -25 to 85°C operation, which may not always be the case for commercial cards, even though dictated by the SD standard. Delkin Utility SD cards are available in capacities from 4GB to 128GB and are ideal for OEM applications that need the benefits of a consistent industrial solution, but do not require the endurance of SLC flash.
