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.

Explanation of Ageing of MLC
Ageing Capacitance measurements
Capacitor ageing is a term used to describe the negative, Because of ageing it is necessary to specify an age for reference
logarithmic capacitance change which takes place in ceramic measurements at which the capacitance shall be within the
capacitors with time. The crystalline structure for barium titanate prescribed tolerance. This is fixed at 1000 hours, since for practical
based ceramics changes on passing through its Curie temperature purposes there is not much further loss of capacitance after this

capacitor is heated to a temperature above the Curie Point the
ageing process starts again from zero. Capacitance vs time
The ageing constant, or ageing rate, is defined as the percentage (Ageing X7R @ <2% per decade)
loss of capacitance due to the ageing process of the dielectric
which occurs during a decade of time (a tenfold increase in age)
and is expressed as percent per logarithmic decade of hours. As
the law of decrease of capacitance is logarithmic, this means that
in a capacitor with an ageing rate of 1% per decade of time, the
capacitance will decrease at a rate of:
a) 1% between 1 and 10 hours
b) An additional 1% between the following 10 and 100 hours ∆c %
c) An additional 1% between the following 100 and 1000 hours
d) An additional 1% between the following 1000 and 10000 C0G/NP0

e) The ageing rate continues in this manner throughout the

computer controlled manufacturing process allows for tolerance as
close as +/-1% on C0G/NP0 parts greater than or equal to 10pF.
For capacitance values below <4.7pF, tolerances can be as tight as

Cleaning
Chip capacitors can withstand common agents such as water,
alcohol and degreaser solvents used for cleaning boards. Ascertain
that no flux residues are left on the chip surfaces as these diminish
electrical performance.
Handling
Ceramics are dense, hard, brittle and abrasive materials. They are
liable to suffer mechanical damage, in the form of chips or cracks, if
improperly handled.
Terminations may be abraded onto chip surfaces if loose chips are
tumbled in bulk. Metallic tracks may be left on the chip surfaces
which might pose a reliability hazard.
Components should never be handled with fingers; perspiration and
skin oils can inhibit solderability and will aggravate cleaning.
Chip capacitors should never be handled with metallic instruments.
Metal tweezers should never be used as these can chip the product
and may leave abraded metal tracks on the product surface.
Plastic or plastic coated metal types are readily available and
recommended - these should be used with an absolute minimum of
applied pressure.
Counting or visual inspection of chip capacitors is best performed
on a clean glass or hard plastic surface.
If chips are dropped or subjected to rough handling, they should
be visually inspected before use. Electrical inspection may also
reveal gross damage via a change in capacitance, an increase in
dissipation factor or a decrease either in insulation resistance or
electrical strength.

Chip Marking System
If required, we can mark capacitors with the EIA 198 two digit code to
show the capacitance value of the part. On chips larger than 3333, or A5 NA5
for leaded encapsulated devices, ink marking is available. However, for
chip sizes 0805 through to 3333 identification marking is accomplished
by using either laser or ink jet printer. This system does not degrade
the ceramic surface, or induce microcracks in the part.
Marking for other sizes may be available upon special request to
determine if applicable; please contact the sales office. Two position alpha numeric marking Three position alpha numeric

Notes: 1) Capacitance in F - min value above max value. 2) *These parts may require conformal coating post soldering. 3) T = Maximum thickness.
4) †Higher capacitance values available from the NC range - see page 63. 5) StackiCap™ high capacitance versions are now available. Please refer to datasheet.
6) Parts in this range may be defined as dual-use under export control legislation as such may be subject to export licence restrictions. Please refer to p12 for
more information on the dual-use regulations and contact the Sales Office for further information on specific part numbers.
