In DC applications polarity is required; if polarity is reversed, the circuit life will be shortened or the capacitor may be damaged. Generally, an intermittent reverse voltage of 1V DC is allowed. If during operation, it is possible that polarity could be reversed or unknown, extensive use of a bipolar capacitor is required.
Charge - Discharge Duty and High Peak-to-Peak Voltage
Charge - Discharge application can generate overheating or overpressure effects on electrolytic capacitors and reduce performances and life. Custom capacitor solutions designed for these specific uses are required, contact us to select the most appropriate item. Kendeil aluminium electrolytic capacitors are suitable for circuits in which a charge and discharge cycle is requested. The frequent cycles due to a charge or discharge operation could take some drop of capacitance value. In general one million of switching with rated voltage one cycle for second a time costant of 0.1 carries an overall capacitance decrease less then 10%.
