Mitsubishi has developed a high-dielectric material that can extend the life of film capacitors

Mitsubishi Materials has developed a high dielectric material that can extend the life of film capacitors. The company said that by improving the material composition and film texture control technology, it has achieved several times the life of current standard products in the accelerated life test under high temperature and high pressure.

The newly developed material is lead zirconate titanate (PZT) type high dielectric Sol-gel liquid. The company currently manufactures and sells PZT-based high-dielectric sol gels for wet-process (sol-gel) film capacitors. This time improvements have been made to the existing material. In the sol-gel method, an organic metal compound solution (sol liquid) is coated on a substrate, dried to form a gel film (colloidal solid), and sintered to obtain a film of a metal oxide film on a substrate. method. It can be manufactured at a lower cost than the general vacuum process (vacuum evaporation method, etc.).
