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
Test Level A

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

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.
All COTS testing includes voltage conditioning and post-electrical
testing as per MIL–PRF–55681. For enhanced reliability, KEMET also
