(3) Notice
o When components are immersed in solvent, be sure to
maintain the temperature of components below the
temperature of solvent.
o Please do not use ultrasonic cleaning.
o Total washing time should be within 4 minutes.
o Please ensure the component is thoroughly evaluated
in your application circuit.
o Please do not use chlorine, petroleum or alkaline
cleaning solvents.
o If you plan to use any other type of solvents, please
consult with Murata or Murata representative prior to
using.
c CDBKB Series Notice (Handling)
1. The component will be damaged when an excessive
stress is applied.
2. If the component is cleaned, please con?rm
that the reliability has not been degraded.
3. In case of covering ?lter with over coating,
conditions such as material of resin, cure
temperature, and so on should be evaluated
carefully.
5. The product, packed in a moisture-proof bag (dry
pack), is sensitive to moisture.
The following treatment is required before
applying re?ow soldering, to avoid package
cracks or reliability degradation caused by
thermal stress. When unpacked, store the component
in an atmosphere of below 25 degrees C. and below
65%R.H., and solder within 48 hours.
4. Do not use strong acidity ?ux, more than 0.2wt%
chlorine content, in re?ow soldering.
