Automotive MLCC with FLEXITERM®, KAF Series
General Specifications
GENERAL DESCRIPTION
With increased requirements from the automotive industry for additional component robustness, KYOCERA 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, KYOCERA 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, KYOCERA AVX launched
FLEXITERM®. FLEXITERM® is designed to enhance the mechanical flexure and temperature cycling performance of
a standard ceramic capacitor. The industry standard for flexure is 2mm minimum. Using FLEXITERM®, KYOCERA
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.
