Axial Through-Hole Multilayer Ceramic Capacitors
Aximax, 400 Series, Axial, Conformally Coated, X8L
Dielectric, 25 – 50 VDC (Commercial & Automotive Grade)
Overview
KEMET’s Aximax conformally coated axial through-hole
ceramic capacitors in X8L dielectric feature a 150°C
maximum operating temperature and is considered
"general purpose high temperature". These components
are fixed, ceramic dielectric capacitors suited for high
temperature bypass and decoupling applications or
frequency discriminating circuits where Q and stability of
capacitance characteristics are not critical. X8L exhibits
a predictable change in capacitance with respect to time
and voltage and boasts a minimal change in capacitance
with reference to ambient temperature up to 125°C. Beyond
125°C X8L displays a wider variation in capacitance.
Capacitance change is limited to ±15% from -55°C to
+125°C and +15, -40% from 125°C to 150°C.
Driven by the demand for a more robust and reliable
component, X8L dielectric capacitors were developed for
critical applications where reliability 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."
