Film capacitors for automotive, industrial and infrastructure use

On a very thin layer of vapor deposited aluminum, segments are made within capacitor’s dielectric material.
Those segments localize the failure caused by over voltage, therefore the damage is only limited in a few section of the capacitor.
When too many of the areas fail in a very short period of time, capacitor will then open in a safe manner.

A demonstration video is available for your to take a look (see below):

• We first apply high voltage to a dielectric material with Panasonic fuse pattern.
• Then we apply the same voltage to the raw material without fuse pattern.
• As you can easily recognize, the damage caused on non-fuse material is far more extensive than that of a fuse material.

Thanks to this “Fuse Function” technology, Panasonic film capacitors are ideal solution for high-stress applications that require high safety and high reliability,
such as automotive applications (OBC, DC/DC converters, inverters for xEV etc.), industrial power supplies, solar inverters etc.
