(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 chambers or transformers. 10 0 ?20 ?10 ?30 ?40 0 50 100 150 capacitance change rate(%) rated voltage(%) 100%=rated voltage 10 0 ?20 ?10 ?30 ?40 0 50 100 150 capacitance change rate(%) rated voltage(%) 100%=rated voltage for more information about products with other capacitance or other data, please contact us.
