!Note • Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.• This catalog has only typical specifications. Therefore, please approve our product specifi cations or transact the approval sheet for product specifi cations before ordering.C85E.pdfApr.7,2014Safety Certified Ceramic Capacitors !CautionContinued from the preceding page.(2) Voltage Applied MethodWhen the withstanding voltage is applied, the capacitor'slead or terminal should be firmly connected to the outputof the withstanding voltage test equipment, and then thevoltage should be raised from near zero to the testvoltage.If the test voltage without the raise from near zero voltagewould be applied directly to capacitor, test voltage shouldbe applied with the zero cross.* At the end of the testtime, the test voltage should be reduced to near zero,and then capacitor's lead or terminal should be taken offthe output of the withstanding voltage test equipment.If the test voltage without the raise from near zero voltagewould be applied directly to capacitor, the surge voltagemay rise, and therefore, a defect may be caused.Voltage sine wave*ZERO CROSS is the point where voltage sine wavepasses 0V. See the figure at right.0Vzero cross4. Fail-SafeWhen the capacitor is broken, failure may result in a shortcircuit. Be sure to provide an appropriate fail-safefunction like a fuse on your product if failure could resultin an electric shock, fire or fuming.FAILURE TO FOLLOW THE ABOVE CAUTIONS MAYRESULT, WORST CASE, IN A SHORT CIRCUITAND CAUSE FUMING OR PARTIAL DISPERSIONWHEN THE PRODUCT IS USED.29
