(2) Example of a suitable machine
An outline of a printed circuit board cropping
machine is shown as follows. Along the lines with
the V-grooves on the printed circuit board, the top
and bottom blades are aligned to one another
when cropping the board.
The misalignment of the position between top and
bottom blades may cause the capacitor to crack.

c Others
1. Under Operation of Equipment
1-1. Do not touch a capacitor directly with bare hands
during operation in order to avoid the danger of an
electric shock.
1-2. Do not allow the terminals of a capacitor to come in
contact with any conductive objects (short-circuit).
Do not expose a capacitor to a conductive liquid,
including any acid or alkali solutions.
1-3. Confirm the environment in which the equipment will
operate is under the specified conditions.
Do not use the equipment under the following
environments.
(1) Being spattered with water or oil.
(2) Being exposed to direct sunlight.
(3) Being exposed to Ozone, ultraviolet rays or
radiation.
(4) Being exposed to toxic gas (e.g., hydrogen sulfide,
sulfur dioxide, chlorine, ammonia gas, etc.)
(5) Any vibrations or mechanical shocks exceeding the
specified limits.
(6) Moisture condensing environments.
1-4. Use damp proof countermeasures if using under any
conditions that can cause condensation.
2. Others
2-1. In an Emergency
(1) If the equipment should generate smoke, fire or
smell, immediately turn off or unplug the equipment.
128
If the equipment is not turned off or unplugged,
the hazards may be worsened by supplying
continuous power.
(2) In this type of situation, do not allow face and
hands to come in contact with the capacitor or
burns may be caused by the capacitor's high
temperature.
2-2. Disposal of Waste
When capacitors are disposed, they must be burned
or buried by an industrial waste vendor with the
appropriate licenses.
2-3. Circuit Design
GRM, GCM, GMA/D, LLL/A/M, GQM, GJM, GNM
Series capacitors in this catalog are not safety
certified products.
2-4. Remarks
Failure to follow the cautions may result, worst case,
in a short circuit and smoking when the product is
used.
The above notices are for standard applications and
conditions. Contact us when the products are used in
special mounting conditions.
Select optimum conditions for operation as they
determine the reliability of the product after assembly.
The data herein are given in typical values, not
guaranteed ratings.
