Introduction to Knowles Capacitors
At Knowles Capacitors we make Single Layer, Multilayer,
High Reliability and Precision Variable Capacitors; EMI Filters
and Thin Film Devices.
Our business was formed by combining Dielectric
Laboratories, Johanson Manufacturing, Novacap, Syfer
Technology and Voltronics into a single organization - each
well-established specialty capacitor makers with a combined
history of over 175 years.
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.
We aim to be a leader in every market we serve, to
the benefit of our customers and our mutual long-
term success. We achieve this by:
l
Understanding our customers’ real needs and providing
products and services to meet and exceed them.
l
Providing better products and services than competitors.
l
Investing in product development, manufacturing
processes and people.
l
Insisting on the highest ethical standards and a business
culture of trust, respect and open communication.
Products in this catalogue form the basis of our ranges for
‘new designs’. However, there are legacy products from
our five brands that will still be available – we ask that you
contact your local Sales Office for details and ordering.
