Polarized aluminum electrolytic capacitors. the capacitance reduced with resultant shortened life. We If you should reverse the polarities of aluminum offer high ripple resistant capacitors especially designed electrolytic capacitors, it would lead to short-circuited for use with high ripple current on request. circuitry and many further results in an explosion if the unit were kept energized. We offer units ofφ8or more with Ripple current safety vent design as the standard type in order to prevent The capacitor should be used within specified permissible possible accidents that may take place if the unit should ripple current in each standard products table. (The sum be connected with its polarities. Small-size capacitors (φ5 of DC voltage and voltage shall not exceed the rated DC ~ φ6) with safety vents are available on request. working voltage.) It is advisable to the use non-polar capacitors for a DC The specified maximum permissible ripple current is circuit where the polarity is reserved. defined at + 85℃ and 120Hz, unless otherwise specified. In other condition of ambient temperature and frequency, Do not apply any over-voltage exceeding the ripple current multiplied by following multiplier can be rated voltage (surge voltage for a short period) applied as maximum permissible ripple current. to the capacitor. When applying ripple current to the capacitor, be very Temperature 40℃ 60℃ 70℃ 85℃ 105℃ careful not to allow the peak voltage value (a value Multiplier 1.9 1.5 1.3 1.0 0.6 obtained by adding the ripple voltage to the DC voltage) to exceed the rated voltage. Application of any voltage higher than the rated value would lead to shortened Frequency 60HZ 120Hz 300Hz 1KHz 10KHz 100KHz service life of the capacitor or would even destroy the unit Multiplier 0.7 1.0 1.1 1.3 1.4 1.4 in a short period. However, the unit may withstand extremely short When you see a capacitor after prolonged application of surge voltage. storage. a) Do not store capacitors at a high temperature or in high Ascertain the operating temperature range. humidity.

Electrolytic capacitor is not suitable for circuits Be careful of temperature and time when in which charge + discharge are frequently soldering. repeated When soldering a printed circuit board with various If used in circuits, in which charge and discharge are components, care must be taken that the soldering frequently repeated, the capacitance value may drop, or temperature is not too high and that the dipping time is not the capacitor may be damaged. Please consult our too long. Otherwise, there will be adverse effects on the engineering department for assistance in these electrolytic capacitor. In the case of small sized electrolytic applications. capacitor, nothing abnormal will occur if dipping is performed at less than 260℃ for less than 10 seconds. Do not allow any higher ripple current than rated to flow through capacitor. If any ripple current higher than the rated value is to flow through a capacitor, excessive heat will be generated and]15
