Knowles Precision Devices (KPD),
a division of Knowles Corporation,
focuses on production of a wide
variety of highly engineered
capacitors and microwave to mmWave
components for use in critical
applications in the military, medical,
electric vehicle and 5G market
segments. The company was formed by
combining Dielectric Laboratories, Johanson
Manufacturing, Novacap, Syfer and
Voltronics, each well-established specialty
capacitor makers with a combined history of
over 200 years, into a single organization.
As a specialty components manufacturer,
Knowles Precision Devices chooses to take
on the complex challenges that come with
high-reliability, high-temperature,
high-performance, and high-frequency
solutions. The Knowles Precision Devices
DLI brand of technologies addresses the
complex challenges of implementing
high-performance mmWave filters across the
widest range of specifications.
