c) The adhesive may cause the marking on the rear surface to disappear, especially in case the regulated
voltage value is indicated on the rear surface. Therefore, the adhesive should not be applied to this area,
and indicated values should be transferred to other locations as a precaution.
d) The notch of the package is used for directional index, and that can not be used for reference of fixing.
In addition, the cover glass and seal resin may overlap with the notch of the package.
e) If the leads are bent repeatedly and metal, etc., clash or rub against the package, the dust may be
generated by the fragments of resin.
f) Acrylate anaerobic adhesives are generally used to attach CCD image sensors. In addition, cyano-
acrylate instantaneous adhesives are sometimes used jointly with acrylate anaerobic adhesives.

a) Do not expose to strong light (sun rays) for long periods, as color filters will be discolored. When high
luminous objects are imaged with the exposure level controlled by the electronic iris, the luminance of
the image-plane may become excessive and discoloring of the color filter will possibly be accelerated. In
such a case, it is advisable that taking-lens with the automatic-iris and closing of the shutter during the
power-off mode should be properly arranged. For continuous using under cruel condition exceeding the
normal using condition, consult our company.
b) Exposure to high temperature or humidity will affect the characteristics. Accordingly avoid storage or
usage in such conditions.
c) Brown stains may be seen on the bottom or side of the package. But this does not affect the CCD
characteristics.
d) This package has 2 kinds of internal structure. However, their package outline, optical size, and strength
are the same.
