About

Syfer Technology Limited has been part of the Dover Corporation since 2000, and is one of the Ceramic Microwave Products (CMP) Companies within Dover Electronics. 

Based in Norwich, UK, we are 150km North East of London, and have been manufacturing multilayer ceramic capacitors for over 35 years.  This wealth of experience in designing and manufacturing MLCCs has enabled us to develop a wide range of multilayer ceramic products. Our comprehensive product range includes many application-specific capacitors, as well as standard voltages and capacitance values. All our products are available in small, medium and large volumes. We also design and manufacture a range of EMI filters including surface mount types for pcb applications, as well as threaded and solder-in panel-mounted styles.

Company approvals include ISO 9001:2008 and ISO 14001:2004, reflecting the importance we place on product quality and reliability. 

Typical applications for our wide range of products include telecoms, power supplies, industrial, automotive, aerospace, space, inverters and backlighting circuits for liquid crystal displays, and this is supported by the various product approvals we currently hold, including CECC, UL and TÜV.

With our global sales team, and a worldwide network of agents and distributors, Syfer is positioned to provide comprehensive technical support and excellent service to its customers. Our goal is to be the premier global source for application specific multilayer capacitor and EMI suppression filter products.
