(1) During transportation and storage
• Do not transport or store where the capacitor will be exposed to high
temperature or high humidity.
• Do not expose to poisonous gases such as H2SO4, HCL or HNO3.
• Avoid excessive impact such as that caused by falling.
(2) During operation
• Avoid contact with electrolytes such as perspiration. Do not touch
with bare hands.
• Avoid excessive impact such as that caused by falling.
• Do not apply solder to stud terminals.
• Do not re-machine the terminals.
(3) Usage
• When the capacitor is used for high-speed pulses such as with a laser,
make sure that the impressed voltage (peak-to-peak volt-age) is within
the capacitor's rated specifications.
• Make sure that the capacitor is not exposed to radiant heat from cham
N4700 ceramic capacitor is successfully developed in recent years, a
new type of ceramic, a ceramic material widely used in high-end
products,compared to other Class I ceramic dielectric constant large,
suitable for larger capacitance, resistance higher voltage, dissipation
factor less than 0.2%, much lower than the average class II ceramic;
insulation resistance is greater than200000MΩ, better frequency and
characteristics of the temperature coefficient, withstand greater current,
Its temperature variation of capacitance is within ±28% from -25°C to
+85°C, it is life of more than 10 years.
