Learn the many benefits and unique properties of film capacitors. Basic construction is Metallized polypropylene film wound around a core, leads are attached, and the capacitor is enclosed in a plastic case, but there is much more.
Y capacitors (for line-to-ground or neutral-to-ground connection). 2.1 X capacitors These are capacitors where failure of the capacitor would not lead to danger of electrical shock but could result in a risk of fire (short-circuit). EN 60384-14 divides X capacitors into 3 sub-classes according to the peak pulse voltage to which they are exposed in operation, in ad-dition to the
Un condensateur est un composant électronique élémentaire, constitué de deux armatures conductrices (appelées « électrodes ») en influence totale et séparées par un isolant polarisable (ou « diélectrique »). Sa propriété principale est de pouvoir stocker des charges électriques opposées sur ses armatures. La valeur absolue de ces charges est proportionnelle à la valeur

Metallized vs. Film/Foil Construction. Here''s how to choose. For a metallized film capacitor, the capacitor plates are aluminum sprayed onto the dielectric film by thin-film vacu-um deposition. Compared to making the capacitor with sep-arate foil and film sheets, met-allizing enables smaller size, lighter weight, lower cost per microfarad and

Film capacitors are versatile components that can be designed into power electronics for industries ranging from consumer and renewables to automotive, aerospace and military. These capacitors come with very specific advantages including non-polarity, a high insulation resistance, low dielectric losses and self-healing capability. Film capacitors

Metalized Film Capacitor Application: In electronic control circuits, including DC link circuits, pulse circuits, switching circuits, etc., metallic film capacitors are commonly used. In decoupling and filtering applications, the low power metalized film capacitor finds use. Ⅵ Features and Applications of Film Capacitors. The film capacitors often provide other features, in
EMI suppression capacitors, as the name implies, are used to reduce electromagnetic interfer-ence. They are connected directly to line and are therefore exposed to overvoltages and tran-sients, which could damage the capacitors. For this reason, EMI suppression capacitors must comply with the requirements of the following safety standards:

EPCOS FK capacitors are produced using either winding methods or stacking methods. In the conventional production process, capacitors are made by individually rolling the metallized films or the film/foils into cylindrical rolls and then covering them with an insulating sleeve or coat-ing.
La taille d''un film peut varier considérablement en fonction de la résolution, de la durée et du format du fichier. En général, un film de qualité standard de deux heures peut avoir une taille de 1 à 2 Go. Les films en haute définition ou en 4K peuvent occuper jusqu''à 30
Plastic film capacitors are generally subdivided into film/foil capacitors and metalized film capacitors. Film / foil capacitors basically consist of two metal foil electrodes that are separated by an insulating plastic film also called dielectric. The terminals are connected to the end-faces of the electrodes by means of welding or soldering.
In this standard, the electrical characteristics of capacitors are described by an idealized series-equivalent circuit with electrical components which model all ohmic losses, capacitive and inductive parameters of a film capacitor:
There are various types of film capacitors designed to serve diferent aspects of electric design. The X (Table 1) and Y (Table 2) types of capacitors are safety, or EMI, capacitors that are generally found in power supply inputs.
Although the materials and the construction of power capacitors are mostly similar to the smaller film capacitors, they are specified and marketed differently for historical reasons. The "film capacitors" were developed together with the growing market of broadcast and electronic equipment technology in the mid-20th century.
The electrodes of metalized film capacitors consist of an extremely thin metal layer (0.02 μm to 0.1 μm) that is vacuum deposited either onto the dielectric film or onto a carrier film. The opposing and extended metalized film layers of the wound capacitor element are connected to one another by flame spraying different metals to the end-faces.
Although the materials and construction techniques used for large power film capacitors are very similar to those used for ordinary film capacitors, capacitors with high to very high power ratings for applications in power systems and electrical installations are often classified separately, for historical reasons.
