Parameters/Characteristics
Regarding aging rate: Capacitance measurements (including tolerance) are indexed to a referee time of 1,000 hours.
To obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits.
Capacitance and dissipation factor (DF) measured under the following conditions:
1 kHz ± 50 Hz and 1.0 ±0.2 Vrms if capacitance ≤ 10 µF
120 Hz ± 10 Hz and 0.5 ±0.1 Vrms if capacitance > 10 µF
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."
KEMET reserves the right to substitute product with an improved temperature characteristic, tighter capacitance tolerance and/or higher voltage capability within
the same form factor (configuration and dimensions).
