Polyester film capacitor have excellent mechanical properties, electrical properties, and optical properties, so they have a wide range of applications, such as photo negatives, magnetic tapes, video tapes, microfilms, packaging films, and capacitors. In addition to photo negatives, the rest need to add anti-sticking agent main feature 1. Metallized polyester film capacitor, non-inductive winding structure. 2. [...]

Capacitor paper is an insulating paper specially designed for making paper capacitors. For web. The paper is even and tight. No holes. Thin as cicada wings. The thickness is 4-10 μm. Has a high mechanical strength. Good air permeability, electrolyte absorption performance and chemical purity. Copper and iron ions, chloride and ash content are extremely low. [...]

There are three main types of tantalum electrolytic capacitor  type: sintered solids, foil-wound solids, and sintered liquids. Among them, sintered solids account for more than 95% of the total production, and the main type is non-metallic sealed resin encapsulation. . The miniaturization and chip-type cooperation with SMT technology are under development. The type of chip sintered [...]

The advantage of  metalized film capacitor is that it has a so-called self-healing effect. That is, if the small part of the electrode is short-circuited due to the weak electrical interface, the electrode metal around the short-circuit part will be caused by the static electricity carried by the capacitor at that time. The energy or short-circuit [...]

The working principle of capacitors is to store electrical energy by storing charges on the electrodes, usually used together with inductors to form an LC oscillation circuit. The working principle of capacitors is that the charge will move under the force of the electric field. When there is a medium between the conductors, it will hinder [...]
