High safety and long life thanks to a built-in fuse function
The damage caused by over-voltages on non-fused material is far more extensive than that suffered by fused material. Therefore Panasonic's film capacitors are the ideal solution for high stress applications.
Comparison between general and patterned metallization:
- Small break down
- Short circuit mode with risk of smoking or burning out
- Fuse function isolates the failed cell, and finally leads to open circuit
- Failed cell is isolated
Panasonic’s In-house technology: Patterned metallized polypropylene film capacitors
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.
