Use capacitors within 6 where chloride gas, sulfide gas, acid, alkali, salt months after delivered. or the like are present. And 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. c Rating 1. Operating Voltage When DC-rated capacitors are to be used in AC or ripple the circuit, starting or stopping may generate irregular current circuits, be sure to maintain the Vp-p value of the voltage for a transit period because of resonance or applied voltage or the Vo-p which contains DC bias within switching. Be sure to use a capacitor with a rated voltage the rated voltage range. When the voltage is applied to range that includes these irregular voltages.

When the capacitor is used in a high-frequency current, Excessive heat may lead to deterioration of the pulse current or similar current, it may self-generate heat capacitor s characteristics and reliability. (Never attempt due to dielectric loss. The applied voltage load should be to perform measurement with the cooling fan running. such that the capacitor s self-generated heat is within Otherwise, accurate measurement cannot be ensured.) 10C at an atmosphere temperature of 25C. c Soldering and Mounting 1. Vibration and Impact Do not expose a capacitor to excessive shock or vibration during use. 2. Installation Installation torque should not exceed the torque strength values inSpecifications and Test Method. Do not use a screw with a thread depth greater than specified. Avoid installation in which any bending torque is applied to the capacitor terminal. Do not rework or resolder the terminal. FAILURE TO FOLLOW THE ABOVE CAUTIONS MAY RESULT, WORST CASE, IN A SHORT CIRCUIT AND CAUSE FUMING OR PARTIAL DISPERSION WHEN THE PRODUCT IS USED.
