It exceeds the nominal and continuous working voltage of the capacitor. Capacitance and dissipation factor (DF) measured under the following conditions: 1 MHz ±100 kHz and 1.0 Vrms ±0.2 V if capacitance ≤ 1,000 pF 1 kHz ± 50 Hz and 1.0 Vrms ±0.2 V if capacitance > 1,000 pF 3 To obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits. Note: When measuring capacitance it is important to ensure the set voltage level is held constant. The HP4284 and Agilent E4980 have a feature known as Automatic Level Control (ALC). The ALC feature should be switched to “ON.” 1 2 Post Environmental Limits High Temperature Life, Biased Humidity, Moisture Resistance Dielectric Rated DC Voltage Capacitance Value Dissipation Factor (Maximum %) C0G All All 0.5 Capacitance Shift Insulation Resistance 0.3% or ±0.25 pF 10% of Initial Limit Electrical Characteristics Energy Density vs. Applied Voltage 0.8 Discharge HT C0G 3,000 Breakdown N2200 0.4 Current (A) Energy Density (J/cc) Competitor N2200 3640 200nF 0.6 0.5 4,000 Breakdown HT C0G KEMET HT C0G 4540 68nF 0.7 Discharge Current vs. Applied Voltage Dischage N2200 0.3 0.2 150nF 1000V 100nF 1250V 68nF 2000V 27nF 3000V 18nF 3500V 2,000 1,000 0.1 0 0 500 1000 1500 2000 Applied Voltage (V) 2500 3000 0 0 500 © KEMET Electronics Corporation • P.O.
