Operating Temperature: Capacitors are designed to operate over the temperature range of - 55 °C to +125 °C. 2. DC Working Voltage: The DC working voltage is the maximum operating voltage for continuous duty at the rated temperature. 3. Surge Voltage: The surge DC rating is the maximum voltage to which the capacitors should be subjected under any conditions. This includes transients and peak ripple at the highest line voltage. The surge voltage of capacitors rated below 150 volts is 115% of the rated DC working voltage. The surge voltage of capacitors rated at 150 volts DC is 165 volts. 3.1 Surge Voltage Test: Capacitors shall withstand the surge voltage test applied through a 1000 ohm ± 10% resistor in series with the capacitor and voltage source at the rate of one-half minute on, four and one-half minutes off, for 1000 successive test cycles at + 85 °C or + 125 °C. 4. Capacitance Tolerance: The capacitance of all capacitors shall be within the specified tolerance limits of the nominal rating. UP TO + 85 °C AT + 125 °C UP TO + 85 °C AT + 125 °C WORKING WORKING WORKING WORKING VOLTAGE VOLTAGE VOLTAGE VOLTAGE (V) (V) (V) (V) 6 4 35 22 8 5 50 30 10 7 60 40 15 10 75 50 20 13 100 70 25 15 125 85 30 20 150 100 4.1 Capacitance measurements shall be made by the bridge method at or referred to, a frequency of 120Hz at a temperature of + 25 °C. A polarizing voltage shall be used of such magnitude that there shall be no reversal of polarity due to the AC component. The maximum AC voltage will be 1 volt rms applied during measurement. 5. Capacitance Change With Temperature: The capacitance change with temperature shall not exceed the limits given in the Standard and Extended Ratings Table for each capacitor. 6. Equivalent Series Resistance: Measurements shall be made by the bridge method at or referred to, a frequency of 120Hz at a temperature of + 25 °C. A polarizing voltage shall be used of such magnitude that there shall be no reversal of polarity due to the AC component. The maximum AC voltage will be 1 volt rms applied during measurement. 6.1. The equivalent series resistance shall not exceed the maximum value in ohms listed in the Standard and Extended Ratings Table for each capacitor. 6.2. The dissipation factor may be calculated from the equivalent series resistance and capacitance values as shown: DF = 2 πfRC 104 where: DF = Dissipation Factor in % R = ESR in ohms C = Capacitance in µF f = frequency in Hz - 55 °C - 40 °C - 20 °C + 25 °C + 85 °C +125 °C 0.2 1.0 10 100 200 FREQUENCY IN HERTZ 100 1K 10K 100K 1M 10M “K” Case 120 µF, 25V Capacitors - 55 °C - 40 °C - 20 °C + 25 °C + 85 °C +125 °C FREQUENCY IN HERTZ 100 1K 10K 100K 1M 10M 0.2 1.0 10 100 200 “C” Case 10 µF. 100V Capacitors Wet Tantalum Capacitors Sintered Anode TANTALEX ® Capacitors Hermetically-Sealed with True Glass-to-Tantalum Seal |
