Product Description

Delkin Devices’ D330 and D400 Series Industrial SD cards utilize true industrial controllers and SLC flash to deliver rugged, high endurance solutions for applications that are write intensive, subject to extreme environmental conditions or which require long term field reliability when recording mission critical data.  The SD form factor has the advantages of being small and lightweight, but Delkin industrial products have many additional benefits over standard retail consumer-grade cards, including BOM control, and life cycle management.

To ensure consistent performance and host compatibility, Delkin locks the card configuration down to the specific controller, firmware and flash chips, with a change to any of these components dictating a new part number.  When an unavoidable EOL occurs to any of these items, Delkin communicates the discontinuation in advance, providing the opportunity to place a last time buy as well as to qualify the replacement solution.

In addition to standard D330 and D400 Series SD, Delkin also offers microSD cards in many configurations, as well as Utility SD and microSD cards, which are cost-effective MLC/3D options for OEM applications.
