Product Description

Utility & Utility+ MLC/Industrial 3D SD

Delkin’s Utility and Utility+ MLC/ Industrial 3D 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. For the harshest of environmental conditions, Utility+ SD cards are rated for the full -40 to +85°C industrial temperature range. Delkin Utility and 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.
