Cactus has an Industrial CF Card to meet any Embedded OEM's Requirements

Cactus Technologies offers three different product series of Industrial CF cards, one of which will meet the specific needs of any Embedded OEM’s system requirements.
Bill-Of-Material (BOM) control and long life cycles are attributes shared by all of our Industrial Grade Compact Flash Cards. As an example, our initial flash card was an Industrial CompactFlash launched in 2005. We still ship this part today - 10 years later.
Two additional series offer higher capacities, performance and feature sets. In regard to feature sets, Cactus also offers special features such as physical write protect switches, military erasure commands and others.
Four different Cactus Industrial CF Series are covered below.
203 Series:

The 203 Series does not support Ultra DMA (UDMA) and has sequential read speeds of 8MB/s and writes of 6MB/s. Due to its lower performance, it is also a lower power device than the 303 or 503 Series.
303 and 303 Pro Series:

The 303 Series supports Ultra DMA (UDMA) up to mode 4 and has sequential read speeds of 35MB/s and writes of 20MB/s.
The 303 Pro Series CompactFlash is based on the 303 Series CF above, but adds the ATA security Feature Set, Multiple Military Erasure Operations and Multiple methods of Write Protect including a physical write protect switch.
503 Series:

The 503 Series supports Ultra DMA (UDMA) up to mode 6 and has sequential read speeds of 50MB/s and writes of 30MB/s. This is the most cost effective Industrial Compact Flash at capacities of 4GB and higher.
Cactus also offers a Industrial MLC CF based on MLC NAND for lower cost and reliability applications. Let us know if you need more information on these Cactus industrial CF cards or any other product.
