m. Dielectric
m. The capacitor is made of low loss Metallized polypropylene film, this self-healing film is a gradient square resistance safety film that uses imported base film and is evaporated using patented technology.
m. The film is rolled into a cylindrical shape using fully automated equipment, using non-inductive winding technology, and thin copper sheet connection technology is used inside the core to make the capacitor have smaller inductance and stronger overcurrent and overvoltage capabilities.
m. Based on long-term use and test results, our capacitor dielectric has very good self-healing properties.
m. We use thickening on the edge of the film to increase the edge contact area, thereby making the contact between the film and the gold-sprayed surface better, increasing the overcurrent capability of the product, and reducing edge stress.
m. Solvent
m. The dielectric filled in the capacitor is to isolate the air between the electrodes. Without the protection of the filling medium, the metal coating will be oxidized, and the metallized film will be increasingly Self-healing, the capacity of the capacitor is getting smaller and smaller, and the loss is getting bigger and bigger.
m. Therefore, when we put the capacitor into the aluminum shell and pour it with polyurethane, the capacitor needs to be vacuum-dried to protect the wound core and its surrounding environment, so that the capacitor can maintain its capacity during long-term use. Very stable.
m. The capacitor is filled with polyurethane, so the capacitor has a high volume utilization ratio, very good self-healing characteristics and over-voltage automatic protection characteristics. When an unexpected situation occurs during operation or the capacitor is overloaded , the capacitor will automatically disconnect internally to ensure safe operation.
