Multilayer Ceramic Chip Capacitor
Part Number:
1812Y1K00103KST
Description:
1812 1000V 10nF ±10% X7R (2R1) to AEC-
Q200
A range of X7R MLC capacitors fully tested and
approved to automotive specification AEC-Q200.
Available in 0603 to 3640 chip sizes with capacitance
values up to 5.6uF as standard. A variety of termination
options are available, including FlexiCap™, the world's
first commercially available flexible termination.
Parts with WS2 suffix use StackiCap™ technology.
Parts with NC suffix code must be conformally coated
after mounting (including between board and chip) to
prevent flashover.

Board Layout
Knowles' conventional 2-terminal chip capacitors can
generally be mounted using pad designs in accordance with
international specification 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 be considered.
Some high voltage parts may require modifications to the
board layout and/or the addition of a conformal coating to
prevent flashover. Refer to application note AN0043 for
further information.

Packaging
Tape packaging information for tape-and-reel parts:
Tape and reel packing of surface mounting chip capacitors for
automatic placement are in accordance with IEC60286-3.
Soldering
Reflow solder in accordance with IPC-A-610. Recommended
reflow profile as laid down in
IPC/JEDEC J-STD-020.
Wave soldering is also possible, but care must be taken for
case sizes 1210 and larger and component thickness
>1.0mm. Trials are encouraged.
Hand soldering is not recommended and can lead to
component damage through thermal shock.
PdAg terminations are primarily intended for conductive epoxy
attachment - they may be suitable for soldering but trials are
recommended.
Application notes with mounting and handling guidance are available on request.
