Utility + microSD

Delkin’s Utility + microSD cards abide by the same controlled BOM and managed life cycle that our standard Utility microSD cards utilize, however they boast an increased operating temperature range from -40 to 85°C to address environments and applications that may get colder than -25°C. Utility and Utility + memory cards are usually kept in stock and are typically available to ship right away without the normal lead time associated with customized solutions, and feature a longer product road map and lifecycle management that you can plan around.

If you have experienced trouble with typical “off the shelf” microSD cards due to changing components or firmware and are in need of a locked BOM, but also do not want or need a customized solution, Utility memory cards are for you! Utility + microSD cards are compliant with the SD 3.0 standard for performance and are built to industrial standards without the high cost of a true SLC industrial solution. We offer Utility + microSDHC in capacities from 4GB through 32GB, and Utility + microSDXC in a 128GB capacity.

Secure Digital


Delkin Devices’ full-size 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.

microSD / microSDHC

The perpetual drive to shrink electronics has made the tiny microSD form factor the fastest growing segment in the industrial and OEM space in recent years.

Utility SD / microSD

Delkin Devices developed the Utility concept for OEM’s and embedded designers that need a cost-effective, yet controlled storage solution. In many cases, the cost of the host and the usage model does not support the use of high-endurance SLC flash, yet the application still requires an industrial-grade product, consistent performance and life cycle management.
