Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)
High Reliability Surface Mount Capacitors,
MIL-PRF-32535, 4 – 100 VDC (X7R Dielectric)
Overview
The KEMET MIL-PRF-32535 X7R surface mount capacitors
are designed, tested and screened to meet demanding
high reliability defense and aerospace applications.
MIL-PRF-32535 is Defense Logistics Agency's (DLA) first
capacitor specification for defense and aerospace that
capitalizes on industry leading base metal electrode (BME)
technology. Qualified under performance specification,
MIL-PRF-32535 and QPL listed, this series meets or
exceeds the requirements outlined by DLA and is
currently available in M (standard reliability) and T (high
reliability) product levels. Driven by the demand for higher
capacitance and smaller case size MLCCs in high reliability
applications, KEMET’s MIL-PRF-32535 X7R provides over
an 55-fold increase in capacitance over MIL-PRF-55681
and MIL-PRF-123, allowing for reduced board space and
continuing the trend for miniaturization.
In addition to being the first BME X7R dielectric qualified for
use in defense and aerospace applications, MIL-PRF-32535 is
the first DLA specification to recognize a flexible termination
option. KEMET's flexible termination utilizes a pliable and
conductive silver epoxy between the base metal and nickel
barrier layers of the termination system. The addition of this
epoxy layer inhibits the transfer of board stress to the rigid
ceramic body, therefore mitigating flex cracks, which can
result in a low IR or short circuit failures.

Rated voltage ≥ 25 V

(Rated voltage applied for 120 seconds maximum at 25°C)
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.

Capacitance and dissipation factor (DF) measured under the following conditions:
1 MHz ±100 kHz and 1.0 V
rms
±0.2 V if capacitance ≤ 1,000 pF
1 kHz ±50 Hz and 1.0 V
rms
±0.2 V if capacitance > 1,000 pF
3
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:
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."
