Dissipation Factor (DF) Maximum Limit at 25°C 5% (6.3 V and 10 V), 3.5% (16 V and 25 V) and 2.5% (50 V to 250 V)

(Rated voltage applied for 120 ±5 seconds at 25°C)
1
Regarding Aging Rate: Capacitance measurements (including tolerance) are indexed to a referee time of 1,000 hours.
2
DWV is the voltage a capacitor can withstand (survive) for a short period of time. It exceeds the nominal and continuous working voltage of the
capacitor.
3
Capacitance and dissipation factor (DF) measured under the following conditions:
1 kHz ±50 Hz and 1.0 ±0.2 V
rms
if capacitance ≤ 10 µF
120 Hz ±10 Hz and 0.5 ±0.1 V
rms
if capacitance > 10 µF
4
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."
