About Us


Based in Hethel, Norwich, UK, we are 150km North East of London, and have been manufacturing multilayer ceramic capacitors for over 40 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, and has enabled us to achieve world firsts with innovations such as FlexiCap™ – flexible terminations to reduce mechanical cracking. 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 and OHSAS 18001:2007, reflecting the importance we place on product quality and reliability, combined with responsibility towards all employees and the environment.  

Typical applications for our wide range of products include telecoms, power supplies, industrial, automotive, aerospace, space, and this is supported by the various product approvals we currently hold, including CECC, UL and TÜV, with qualification also to AEC-Q200.

With our global sales team, and a worldwide network of agents and distributors, Knowles  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.
