capacitors in Ultra-Stable X8R dielectric feature a 150°C
maximum operating temperature, offering the latest in high
temperature dielectric technology and reliability for extreme
temperature applications. It offers the same temperature
capability as conventional X8R, but without the capacitance
loss due to applied DC voltage. Ultra-Stable X8R exhibits no
change in capacitance with respect to voltage and boasts
a minimal change in capacitance with reference to ambient
temperature. It is a suitable replacement for higher capacitance
and larger footprint devices that fail to offer capacitance
stability. Capacitance change with respect to temperature is
limited to ±15% from -55ºC to 150ºC. Driven by the demand
for a more robust and reliable component, the Ultra-Stable X8R
dielectric Aximax though-hole capacitors were developed for
critical applications where reliability and capacitance stability at
higher operating temperatures are a concern. These capacitors
are widely used in automotive circuits as well as general high
temperature applications.
In addition to Commercial Grade, Automotive Grade devices
are available and meet the demanding Automotive Electronics
Council's AEC-Q200 qualification requirements.
These devices meet the flame test requirements outlined in UL
Standard 94V-0.

Parameters/Characteristics
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 MHz ±100 kHz and 1.0 ±0.2 Vrms if capacitance ≤ 1,000 pF
1 kHz ±50 Hz and 1.0 ±0.2 Vrms if capacitance > 1,000 pF
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."
