(2) Soldering Iron
Filter is soldered at +350±5°C for 3.0±0.5 seconds. The
soldering iron should not touch the filter while soldering.
(3) Conditions for Placement Machines
The component is recommended for use with placement
machines that employ optical placement capabilities.
Damage may result from excessive mechanical force.
Please make sure that you have evaluated by using
placement machines before going into mass production.
Do not use placement machines that utilize mechanical
positioning. Please contact Murata for details beforehand.
(4) Other
(a) The component may be damaged if excess
mechanical stress is applied to it mounted on the
printed circuit board.
(b) Design layout of components on the PC board to
minimize the stress imposed on the warp or flexure of
the board.
(c) After installing chips, if solder is excessively applied to
the circuit board, mechanical stress will cause

accuracy, etc. Careful checking and maintenance are
necessary to prevent unexpected trouble.
(e) When correcting chips with a soldering iron, the tip of
the soldering iron should not directly touch the chip
component.
2. Wash
Do not clean or wash the component as it is not
hermetically sealed.
