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.
