High safety and long life thanks to a built-in fuse function

Capacitor: Film Built in fuse function Panasonic Industry

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:

  1. Small break down
  2. Short circuit mode with risk of smoking or burning out
  3. Fuse function isolates the failed cell, and finally leads to open circuit
  4. 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.
