Knowles Safety Certified capacitors comply with
international UL and TÜV specifications to offer
designers the option of using a surface mount ceramic
multilayer capacitor to replace leaded film types.
Offering the benefits of simple pick-and-place
assembly, reduced board space required and lower
profile, they are also available in a FlexiCap™ version to
reduce the risk of mechanical cracking.
Knowles high voltage capacitor expertise means the
range offers among the highest range available of
capacitance values in certain case sizes. Applications
include: modems, AC-DC power supplies and where
lightning strike or other voltage transients represent a
threat to electronic equipment.

Soldering Information
Knowles / Syfer MLCCs are compatible with all recognised
soldering/mounting methods for chip capacitors. A detailed
application note is available at
www.knowlescapacitors.com/syfer
Reflow Soldering
Knowles recommend reflow soldering as the preferred method
for mounting MLCCs. Knowles MLCCs can be reflow soldered
using a reflow profile generally defined in IPC/FEDEC J-STD-
020. Sn plated termination chip capacitors are compatible with
both conventional and lead free soldering with peak
temperatures of 260º to 270ºC acceptable.
The heating ramp rate should be such that components see a
temperature rise of 1.5º to 4ºC per second to maintain
temperature uniformity through the MLCC.
The time for which the solder is molten should be maintained
at a minimum, so as to prevent solder leaching. Extended
times above 230ºC can cause problems with oxidation of Sn
plating. Use of an inert atmoshere can help if this problem is
encountered. Palladium/Silver (Pd/Ag) terminations can be
particularly susceptible to leaching with free lead, tin rich
solders and trials are recommended for this combination.
Cooling to ambient temperature should be allowed to occur
naturally, particularly if larger chip sizes are being soldered.
Natural cooling allows a gradual relaxation of thermal
mismatch stresses in the solder joints. Forced cooling should
be avoided as this can induce thermal breakage.
Wave Soldering
Wave soldering is generally acceptable, but the thermal
stresses caused by the wave have been shown to lead to
potential problems with larger or thicker chips. Particular care
should be taken when soldering SM chips larger than size 1210
and with a thickness greater than 1.0mm for this reason.
Maximum permissable wave temperature is 270ºC for SM
chips.
The total immersion time in solder should be kept to a
minimum. It is strongly recommended that Sn/Ni plated
terminations are specified for wave soldering applications.
Solder Leaching
Leaching is the term for the dissolution of silver into the solder
causing a failure of the termination system which causes
increased ESR, tan δ and open circuit faults, including
ultimately the possibility of the chip becoming detached.
Leaching occurs more readily with higher temperature solders
and solders with a high tin content. Pb free solders can be very
prone to leaching certain termination systems. To prevent
leaching, exercise care when choosing solder allows and
minimize both maximum temperature and dwell time with the
molten solder.
Plated terminations with nickel or copper anti-leaching barrier
layers are available in a range of top coat finishes to prevent
leaching occurring. These finishes also include Knowles
FlexiCap
TM
for improved stress resistance post soldering.
Multilayer ceramic chip with nickel or copper barrier
terminat
ion
Rework of Chip Capacitors
Knowles recommend hot air/gas as the preferred method of
applying heat for rework. Apply even heat surrounding the
component to minimise internal thermal gradients. Soldering
irons or other techniques that apply direct heat to the chip or
surrounding area, should not be used as these can result in
micro cracks being generated.
Minimise the rework heat duration and allow components to
cool naturally after soldering.
Use of Silver Loaded Epoxy Adhesives
Chip capacitors can be mounted to circuit boards using silver
loaded adhesive provided the termination material of the
capacitor is selected to be compatible with the adhesive. This
is normally PdAg. Standard tin finishes are often not
recommended for use with silver loaded epoxies as there can
be electrical and mechanical issues with the joint integrity due
to material mismatch.
Handling & Storage
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 theses
can chip the product and leave abraded metal tracks on the
product surface. Plastice or plastic coated metal types are
readily available and recommended – these should be used
with an absolute minimum of applied pressure.
Incorrect storage can lead to problems for the user. Rapid
tarnishing of the terminations, with an associated degradation
of solderability, will occur if the product comes into contact
with industrial gases such as sulphur dioxide and chlorine.
Storage in free air, particularly moist or polluted air, can result
in termination oxidation.
Packaging should not be opened until the MLCs are required
for use. If opened, the pack should be re-sealed as soon as
practicable. Alternatively, the contents could be kept in a
sealed container with an envirinmental control agent.
Long term storage conditions, ideally, should be temperature
controlled between -5º and +40ºC and humidity controlled
between 40 and 60% R.H.
Taped product should be stored out of direct sunlight, which
might promote deterioration in tape or adhesive performance.
Product, store under the conditions recommended above, in its
“as received” packaging, has a minimum shelf life of 2 years.
SM Pad Design
Knowles conventional 2-terminal chip capacitors can generally
be mounted using pad designs in accordance with IPC-7351,
Generic Requirements for Surface Mount Design and Land
Pattern Standards, but there are some other factors that have
been shown to reduce mechanical stress, such as reducing the
pad width to less than the chip width. In addition, the position
of the chip on the board should also be considered.
3-terminal components are not specifically covered by IPC-
7351, but recommended pad dimensions are included in the
Knowles catalogue/website for these components.
