Automotive Grade Capacitors
At Knowles Precision Devices (KPD), we manufacture Single Layer, Multilayer, High Reliability and Precision
Variable Capacitors; EMI Filters and Thin Film Devices. One of our fields of expertise is the design and
manufacture of components important to engineers in the automotive industry. Today’s vehicles have
many electronic control units that enable absolute precision and control.
The Automotive Electronics Council (AEC) Component Technical Committee is the standardization body
for establishing standards for reliable, high-quality electronic components. Components meeting these
specifications are suitable for use in the harsh automotive environment without additional component-level
qualification testing.
The Component Technical Committee established AEC-Q200 “Stress Test Qualification for Passive
Components” to define the minimum stress test driven qualification requirements for electrical devices,
including ceramic capacitors. KPD’s Syfer brand has developed a range of MLC capacitors and surface mount
EMI filters qualified to AEC-Q200 rev D to meet the needs of high reliability and automotive manufacturers.
Knowles Suzhou (China), Norwich (England) and Penang (Malaysia) facilities are accredited to IATF
16949:2016 for the design, manufacture and supply of AEC-Q200 qualified MLCC components. Please
refer to the following pages for details of the product ranges offered.

Dielectric Characteristics
CLASS I DIELECTRICS
Multilayer Ceramic Capacitors are generally divided into classes,
which are defined by the capacitance temperature characteristics
over specified temperature ranges. These are designated by alpha-
numeric codes. Code definitions are summarized below and are also
available in the relevant national and international specifications.
Capacitors within this class have a dielectric constant range from 10
to 100. They are used in applications that require ultra stable
dielectric characteristics with negligible dependence of
capacitance and dissipation factor with time, voltage and
frequency. They exhibit the following characteristics:
a) Time does not significantly affect capacitance and dissipation
factor (Tan δ) – no aging.
b) Capacitance and dissipation factor are not affected by voltage.
c) Linear temperature coefficient.

Dielectric Characteristics
CLASS II DIELECTRICS
Capacitors of this type have a dielectric constant range of 1000-
4000 and also have a nonlinear temperature characteristic that
exhibits a dielectric constant variation of less than ±15% (2R1)
from its room temperature value, over the specified temperature
range. Generally used for bypassing (decoupling), coupling,
filtering, frequency discrimination, DC blocking and voltage transient
suppression with greater volumetric efficiency than Class I units,
while maintaining stability within defined limits.
Capacitance and dissipation factors are affected by:
a) Time (Aging)
b) Voltage (AC or DC)
c) Frequency
