About Knowles Precision Devices
At Knowles Precision Devices, we make Multilayer, High Reliability, Single Layer and Precision Variable Capacitors; EMI Filters; and RF/Microwave Components including RF Filters, Splitters and Couplers. Our business was formed by combining Compex Corporation, Dielectric Laboratories, Johanson Manufacturing, Novacap, Syfer, and Voltronics, each well-established specialty component makers with a combined history of more than 200 years, into a single organization.
Our expertise is the design and manufacture of high-performance 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.
Our capacitors and RF devices are used in some of the most complex and mission-critical applications, from 8000 feet below the earth’s surface to orbiting 254 miles above us on the International Space Station. If you have a complex technical challenge with hard-to-meet performance, size, or reliability requirements, bring it to us. It’s what we do.
