GENERAL DESCRIPTION
With increased requirements from the automotive industry for additional
component robustness, AVX recognized the need to produce a MLCC with
enhanced mechanical strength. It was noted that many components may be
subject to severe flexing and vibration when used in various under the hood
automotive and other harsh environment applications.
To satisfy the requirement for enhanced mechanical strength, AVX had to
find a way of ensuring electrical integrity is maintained whilst external forces
are being applied to the component. It was found that the structure of the
termination needed to be flexible and after much research and development,
AVX launched FLEXITERM
®
. FLEXITERM
®
is designed to enhance the
mechanical flexure and temperature cycling performance of a standard
ceramic capacitor with an X7R dielectric. The industry standard for
flexure is 2mm minimum. Using FLEXITERM
®
, AVX provides up to
5mm of flexure without internal cracks. Beyond 5mm, the capacitor
will generally fail “open”.
As well as for automotive applications FLEXITERM
®
will provide Design
Engineers with a satisfactory solution when designing PCB’s which may be
subject to high levels of board flexure.
