Treatment after Bonding, Resin Molding and Coating Caution c Storage and Operation Conditions The insulating coating of capacitors does not form a perfect seal therefore, do not use or store capacitors in a corrosive atmosphere, especially where chloride gas, sulfide gas, acid, alkali, salt or the like are present. Also avoid exposure to moisture. Before cleaning, bonding or molding this product, verify that these processes do not affect product quality by testing the performance of a cleaned, bonded or molded product in the intended equipment. Store the capacitors where the temperature and relative humidity do not exceed 5 to 40 degrees centigrade and 20 to 70%. Use capacitors within 6 months after delivery. c Rating 1. Operating Voltage When DC-rated capacitors are to be used in AC or ripple When DC-rated capacitors are to be used in input circuits current circuits, be sure to maintain the Vp-p value of the from commercial power source (AC filter), be sure to use applied voltage or the V0-p which contains DC bias within Safety Recognized Capacitors because various the rated voltage range. regulations on withstand voltage or impulse withstand When the voltage is applied to the circuit, starting or established for all equipment should be taken into stopping may generate irregular voltage for a transit consideration. period because of resonance or switching. Be sure to use a capacitor with a rated voltage range that includes these irregular voltages.

Operating Temperature and Self-generated Heat Keep the surface temperature of a capacitor below the When measuring, use a thermocouple of small thermal upper limit of its rated operating temperature range. Be capacity -K of 0.1mm under conditions where the sure to take into account the heat generated by the capacitor is not affected by radiant heat from other capacitor itself. When the capacitor is used in a components or wind from surroundings. Excessive heat high-frequency current, pulse current or similar current, it may lead to deterioration of the capacitor s characteristics may have self-generated heat due to dielectric loss. In and reliability. Never attempt to perform measurement the case ofHigh Dielectric Constant Type Capacitors with the cooling fan running. Otherwise, accurate applied voltage load should be such that self-generated measurement cannot be ensured. heat is within 20 C under the condition where the capacitor is subjected at an atmosphere temperature of 25 C. Please contact us if self-generated heat occurs withTemperature Compensating Type Capacitor. 3. Fail-Safe Be sure to provide an appropriate fail-safe function on your product to prevent a second damage that may be caused by the abnormal function or the failure of our product.
