Our support team is very familiar with many of our customers' specific applications, especially those in telecommunications equipment, industrial controls, consumer products, alarms, motherboards, medical devices, and military gear. For example, the battery holders made for medical applications must be manufactured in zero-defect processes and be resistant to organic growth. The military sector requires battery holders featuring extreme shock and vibration resistance with no loss of power continuity. Telecommunications, alarms, motherboards, and many stationary consumer items use their batteries only for back-up power, and so they require long-lasting, oxidation-free holder solutions. We have learned the specific needs of each industry we sell to and have crafted products specifically to meet those needs. Less...

More about Memory Protection Devices

Memory Protection Devices, Inc. (MPD) is an ISO 9001 certified global manufacturer of battery holders, battery contacts, auto plugs, auto sockets, fuse holders, DC jacks, DC plugs, and other electronic components and devices. Our parts are manufactured to rigorous standards in factories located around the world, which meet not only our quality requirements, but our social ones as well. We believe that many components have not been given as much thought as they deserve, and every day we work to find the next innovative design. After all, a defective component can cause complete failure in most devices, and a poorly designed one can cause many inconveniences to end users. It is due to this core value that MPD is viewed as the industry's leading innovator.

Corporate History

MPD was originally founded in 1980 by three executives with a wealth of experience in the electronics industry. Today, the company is being led into an era of fresh growth under a new president with over 30 years of experience. The company's name, Memory Protection Devices, refers to the initial usage of our battery holders, which was to power CMOS RAM, a special type of computer memory that is used to store system settings. Although we are still protecting memory with our battery holders, MPD has since branched out and we now have a diverse line of products.

Fuse holders come made for a variety of applications, such as for general PCB placement, panel-mounting, and in-line placement. Fuse clips are designed to directly mount fuses to PCBs using through hole pins. Although fuse clips are less reliable than fuse holders, they are still reliable for most applications and can deliver great cost savings.
