Qualification/Certification
Commercial Grade products are subject to internal qualification. Details regarding test methods and conditions are referenced in
Table 4, Performance & Reliability.
Automotive Grade products meet or exceed the requirements outlined by the Automotive Electronics Council. Details regarding test
methods and conditions are referenced in document AEC–Q200, Stress Test Qualification for Passive Components. For additional
information regarding the Automotive Electronics Council and AEC–Q200, please visit their website at www.aecouncil.com.
Environmental Compliance

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."
