Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)
Commercial Off-the-Shelf (COTS) for Higher Reliability
Applications, X7R Dielectric, 6.3 – 250 VDC
Overview
KEMET’s COTS program is an extension of KEMET knowledge
of high reliability test regimes and requirements. KEMET
regularly supplies “up-screened” products by working with
customer drawings and imposing specified design and test
requirements. The COTS program offers the same high quality
and high reliability components as up-screened products,
but at a lower cost to the customer. This is accomplished by
eliminating the need for customer-specific drawings to achieve
the reliability level required for customer applications. A series
of tests and inspections have been selected to provide the
accelerated conditioning and 100% screening necessary to
eliminate infant mortal failures from the population.
All COTS testing includes voltage conditioning and post-electrical
testing as per MIL–PRF–55681. For enhanced reliability, KEMET
also provides the following test level options and conformance
certifications:

KEMET’s X7R dielectric features a 125°C maximum operating
temperature and is considered “temperature stable.” The
Electronics Components, Assemblies & Materials Association
(EIA) characterizes X7R dielectric as a Class II material.
Components of this classification are fixed, ceramic dielectric
capacitors suited for bypass and decoupling applications or
for frequency discriminating circuits where Q and stability of
capacitance characteristics are not critical. X7R exhibits a
predictable change in capacitance with respect to time and
voltage and boasts a minimal change in capacitance with
reference to ambient temperature. Capacitance change is
limited to ±15% from -55°C to +125°C.
