4. Cleaning
Please confirm there is no problem in the reliability of the
product beforehand when cleaning it with the intended
equipment.
The residue after cleaning it might cause the decrease in
the surface resistance of the chip and the corrosion of the
electrode part, etc. As a result it might cause reliability to
deteriorate. Please confirm beforehand that there is no
problem with the intended equipment in ultrasonic
cleansing.
5. Resin Coating
Please use it after confirming there is no influence on the
product with a intended equipment beforehand when the
resin coating and molding.
A cracked chip might be caused at the cooling/heating
cycle by the amount of resin spreading and/or bias
thickness.
The resin for coating and molding must be selected as
the stress is small when stiffening and the hygroscopic is
low as possible.

1. Capacitance change of capacitor
2. Performance check by equipment
(1) In case of X7R char.
Before using a capacitor, check that there is no
problem in the equipment's performance and the
specifications.
Capacitors have an aging characteristic, whereby
the capacitor continually decreases its
capacitance slightly if the capacitor is left on
for a long time. Moreover, capacitance might change
greatly depending on the surrounding temperature
or an applied voltage. So, it is not likely to be
suitable for use in a time constant circuit.
Please contact us if you need detailed information.
(2) In case of any char. except X7R
Generally speaking, CLASS 2 (X7R char.) ceramic
capacitors have voltage dependence characteristics
and temperature dependence characteristics in
capacitance. So, the capacitance value may change
depending on the operating condition in the equipment.
Therefore, be sure to confirm the apparatus
performance of receiving influence in a capacitance
value change of a capacitor, such as leakage current
and noise suppression characteristics.
Capacitance might change a little depending on the
surrounding temperature or an applied voltage.
Please contact us if you intend to use this product
in a strict time constant circuit.
Moreover, check the surge-proof ability of a
capacitor in the equipment, if needed, because the
surge voltage may exceed specific value by the
inductance of the circuit.
