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.

StackiCap™ Capacitors - X7R
The StackiCap™ range offers a significant reduction in ‘PCB real
estate’ for an equivalent capacitance value when board space is at a
premium. For example, a standard 150nF chip in a 8060 case size is
now available in a much smaller 3640 case size.
Knowles’s unique patented* construction and FlexiCap™ termination
material make the StackiCap™ range suitable for applications
including: power supplies, lighting, aerospace electronics and
high voltage applications where a large amount of capacitance is
required. Further developments are on-going, please contact the
Sales Office for details of the full range.
* StackiCap™ technology is protected by international patents (pending) EP2847776,
WO2013186172A1, US20150146343A1 and CN104471660A.

NC Capacitors - X7R
MLCCs are particularly suitable for high voltage applications where
small size is required. For standard high voltage capacitors a
coating may be required to be applied post soldering.
The NC range is designed to achieve the maximum capacitance
range possible for a given component size and high voltage, but
100% coating of the chip after mounting, including especially
between the board and the component (between the mounting
pads) is mandatory to ensure flashover does not occur. To ensure
the coating achieves total coverage around all four exposed sides of
the chip, it may be necessary to slot or cut the PCB under the chip.
Knowles / Syfer application note AN0043 gives more information on
the coating requirements.
This range is fully compliant with the RoHS, REACH and WEEE
directives.
