Knowles Capacitors

Knowles Capacitors manufactures  Multilayer, High Reliability, Single Layer and Precision Variable Capacitors, EMI Filters and Thin Film Devices. Our business was formed by combining Dielectric Laboratories, Novacap, Syfer and Voltronics, each well-established specialty capacitor makers with a combined history of over 175 years, into a single organization with manufacturing and R&D locations in North America, Asia and Europe.

Our expertise is the design and manufacture of components important to engineers in applications where function and reliability are key. The markets we serve include medical implantable and medical equipment, military, aerospace/avionics, EMI and connector filtering, oil exploration, instrumentation, industrial electronics, optical networks, telecom and automotive.
Capacitor types range from 0.47pF to 22µF and from 10Vdc to 12kVdc in SMD or leaded packages, including surface mount chip, radial leaded, ultra low ESR , High 'Q', surge protection and safety capacitors for Class X and Y applications, low inductance, high temperature and stacked chip capacitors. The Knowles product range includes standard and high voltage ceramic chip capacitors through to application specific capacitor assemblies and highly complex planar capacitor arrays.
It also designs and manufactures a range of EMI filters ranging from 10pF to 2.2µF with working voltages to 3kVdc, including SMD 'C' and pi-filters, X2Y Integrated Passive Components, threaded and solder-in panel mounted styles, planar arrays for filter connectors and discoidal capacitors.
Knowles currently has ISO 9001 Company Approval. Product approvals include CECC, UL, TÜV and Semko.
All standard surface mount chip capacitors are RoHS compliant, and are suitable for lead-free soldering processes. See the Knowles Capacitors website www.knowlescapacitors.com for further RoHS and WEEE details for these and the other product ranges.
