It exceeds the nominal and continuous working voltage of the capacitor. 2 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.” Post Environmental Limits High Temperature Life, Biased Humidity, Moisture Resistance Dielectric Rated DC Voltage Capacitance Value Dissipation Factor (Maximum %) Capacitance Shift Insulation Resistance C0G All All 0.5 0.3% or ±0.25 pF 10% of Initial Limit Electrical Characteristics Discharge Current vs. Applied Voltage 0 1,000 2,000 3,000 4,000 0 500 1,000 1,500 2,000 2,500 3,000 3,500 4,000 Applied Voltage (V) 150nF 1000V 100nF 1250V 68nF 2000V 27nF 3000V 18nF 3500V Energy Density vs. Applied Voltage 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0 500 1,000 1,500 2,000 2,500 3,000 Applied Voltage (V) KEMET HT C0G 4540 68nF Competitor N2200 3640 200nF Breakdown HT C0G Breakdown N2200 Discharge N2200 Discharge HT C0G |
