Welcome to Weijie Semiconductor

Memory Protection Devices

- Memory Protection Devices is a world-class designer and supplier of electronic components of power connection technology. Our specialties include battery holders, battery contacts, 12 volt auto assemblies and connectors. Because of the focused nature of our product line, we offer the highest quality parts in the industry and competitive pricing. This commitment to excellence is reflected in our certification as an ISO 9001:2000 company. Some of the services we offer to clients include personal customer service, custom manufacturing, and unmatched technical support.

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.
