Syfer AEC-Q200 Flexicap MLCCs
Knowles Syfer AEC-Q200 Flexicap Multilayer Ceramic Capacitors (MLCC) are suitable for harsh automotive environments. These capacitors are available in a voltage range of up to 4kV for the requirements of modern automotive applications. The AEC-Q200 Flexicap capacitors operate over a temperature range from -55°C to +125°C. These components provide high reliability, flexible termination, and protection from short circuit failures. AEC-Q200 Flexicap capacitors are used in battery management, DC/DC converters, and electric vehicles.

This TTI Tech Specs video for Knowles Syfer FlexiCap Range of MLCCs explains that Knowles FlexiCap technology tolerates high mechanical stress before mechanical cracking occurs. This flexibility also allows the capacitors to be thermally cycled over 1000 times without cracking.

You’ll never see me on a yoga mat doing the king pigeon pose. You basically bend your whole body backwards until you’re face down with your head between your feet. If I tried, there would probably be lots of cracking and failing, because I’m about as flexible as a traditional MLCC. Knowle’s FlexiCap technology can’t help me do yoga, but the flexible terminations can help your MLCCs tolerate much greater flexing before mechanical cracking occurs. This flexibility also allows the capacitors to be thermal cycled over 1,000 times without cracking.
FlexiCap MLCCs have a flexible epoxy polymer termination material applied beneath the standard nickel barrier finish and has no adverse effect on electrical performance. Knowles offers a huge range of MLCCs with FlexiCap technology, including AEC-Q200 options as well as capacitors for high reliability, high voltage, high temperature, and many more applications.
