■ CERAFILr 455kHz Chip Type PFWCC Series
1. The component may be damaged if excess mechanical
stress is applied to it mounted on the printed circuit
board.
2. Design layout of components on the PC board to
minimize the stress imposed on the warp or flexure of the
board.
3. After installing chips, if solder is excessively applied to
the circuit board, mechanical stress will cause destruction
resistance characteristics to lower. To prevent this, be
extremely careful in determining shape and dimension
before designing the circuit board diagram.
4. For safety purposes, connect the output of filters to the IF
amplifier through a D.C. blocking capacitor. Avoid
applying a direct current to the output of ceramic filters.

■ CERAFILr 455kHz Chip Type SFPKA Series
1. The component will be damaged when an excessive
stress is applied.
2. Use coupling capacitors to prevent applying D.C.
voltage between input-ground, output-ground of
"CERAFIL" as D.C. current may harm the component.
3. In the case that the component is cleaned, confirm
that no reliability degradation is created.
4. In case of covering filter with over coat,
conditions such as material of resin, cure
temperature, and so on should be evaluated
carefully.
5. Do not use strong acidity flux, more than 0.2wt%
chlorine content, in re-flow soldering.
6. The product, packed in the moisture-proof bag
(dry pack), is sensitive to moisture. The following
treatment is required before applying re-flow
soldering, to avoid package cracks or reliability
degradation caused by thermal stress. When unpacked,
store the component in an atmosphere of below 25
degree C and below 65%R.H., and solder within 48
hours.
7. For safety purposes, connect the output of filters
to the IF amplifier through a D.C. blocking
capacitor. Avoid applying a direct current to the
output of ceramic filters.
■ CERAFILr 3.5-6.5MHz Lead Type
1. Do not use this product with bend. The component
may be damaged if excess mechanical stress is
applied to it mounted on the printed circuit board.
2. The component may be damaged when an excessive stress
is applied.
3. All kinds of re-flow soldering must not be applied
on the component.
4. Do not clean or wash the component as it is not
hermetically sealed.
5. Please contact Murata or Murata representative for
soldering condition, in case of using lead free
solder.
6. Do not use strong acidity flux, more than 0.2wt%
chlorine content, in flow soldering.
7. In case of covering filter with over coat,
conditions such as material of resin, cure
temperature, and so on should be evaluated
carefully.
8. Accurate test circuit values are required to
measure electrical characteristics. It may be a
cause of miscorrelation if there is any
deviation, especially stray capacitance, from the
test circuit in the specification.
9. For safety purposes, connect the output of filters
to the IF amplifier through a D.C. blocking
capacitor. Avoid applying a direct current to the
output of ceramic filters.
