Product Description

Delkin Devices’ D200 Series SD cards utilize a true industrial controller and SLC flash to deliver a rugged, high endurance solution 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, life cycle management and even Extended Life Cycle (ELC) configurations that will be in production through 2021.

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.

Additionally, since Delkin designs, manufactures and supports the Industrial SD cards at our Poway, California facility, we can also provide customized SD solutions, whether a special label, content or image loading, conformal coating or mechanical modifications to meet a specific need.  Contact us to ask how a card can be customized for your application.

In addition to standard D200 Series SD, Delkin also offers D200 ELC SLC Extended Life Cycle (ELC) SD cards and microSD cards in many configurations, as well as Utility SD and microSD cards, which are cost-effective MLC options for OEM applications.
