GENERAL DESCRIPTION
With increased requirements from the automotive industry for additional
component robustness, AVX recognized the need to produce aMLCC 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
away 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 astandard
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 asatisfactory solution when designing PCB’s which may be
subject to high levels of board flexure.

TEMPERATURE CYCLE TEST PROCEDURE
Test Procedure as per AEC-Q200:
The test is conducted to determine the resistance of the
component when it is exposed to extremes of alternating
high and low temperatures.
Sample lot size quantity 77 pieces
TC chamber cycle from -55ºC to +125ºC for 1000 cycles
Interim electrical measurements at 250, 500, 1000 cycles
Measure parameter capacitance dissipation factor,
insulation resistance

0805 >2mm >5mm apart (capacitor side down)
1206 >2mm >5mm The row of capacitors is aligned with the
load stressing knife
The load is applied and the deflection where
the part starts to crack is recorded (Note:
Equipment detects the start of the crack
using a highly sensitive current detection
circuit)
