Audio Grade Capacitors

Audio Grade Capacitors

A Question that a Lot of People Debate On is " Why Audio Grade Capacitors".
Audio Grade is Now A days a Common Term Used for a Lot of Audio Related Parts and it is often a term used in a lot of debates over Audio Components. In terms Of Capacitors we have tried to summarize the Basic Factors that Define the Quality of MKP / Foil type Crossover Capacitors . Audio MKP (metallized polypropylene) capacitors, also known as film capacitors, are widely used in audio equipment due to their excellent electrical properties and performance characteristics. Here's an overview of how these capacitors are typically made:
Film Extrusion: The process begins with the extrusion of polypropylene film. Polypropylene pellets are melted and then passed through a die to form a continuous film. This film will serve as the dielectric material for the capacitor.
Metallization: One or both sides of the polypropylene film are metallized to create a thin layer of metal (usually aluminum) on the film's surface. This metallization process is commonly performed using vacuum deposition techniques, where metal vapor is deposited onto the film under controlled conditions.
 Winding: The metallized polypropylene film is then wound into a cylindrical shape, forming the capacitor's structure. Depending on the desired capacitance and voltage rating, multiple layers of film may be used, and they can be wound in parallel or series configurations.
 Electrode Termination: Once the winding is complete, the capacitor's electrodes are formed. Metal foils or metal wires are attached to each end of the wound film to serve as the capacitor's terminals.
Impregnation (Optional): In some cases, the wound capacitor can be impregnated with a dielectric fluid, which further enhances its electrical properties and increases its ability to handle higher voltages.
 Encapsulation: The wound and terminated capacitor is then placed inside an appropriate casing, often made of plastic or other insulating materials, to protect it from environmental factors and ensure electrical safety.
