Film capacitors, also known as polyester capacitors, are non-polarized components that are highly preferred for a wide range of electronic circuits. MKT1820415106 is a special type of film capacitor.

Design

MKT1820415106 film capacitors are constructed by winding a dielectric polyester film between two electrodes. The electrodes are made of aluminum and are insulated from each other by a 0.2mm amorphous film. The leads of the capacitor are made of tinned copper or silver plated nickel. The glass-covered electrodes are connected to the leads using aluminum crimping. The electrodes and leads are heated to a temperature of 130°C and then cooled to ensure that the connection is strong and reliable.

Features

• Low leakage current
• High ripple current capability
• High stability
• Excellent temperature characteristics
• High insulation resistance

Application fields

MKT1820415106 film capacitors are well suited for a variety of applications, including low frequency and high frequency circuits, power supply filters, smoothing filters, coupling or AC blocking, signal filtering, EMI/RFI noise reduction, and surge suppression. They can also be used in high temperature applications as they do not suffer from melting or oil leakage.

Due to their excellent performance characteristics, MKT1820415106 film capacitors are used in a variety of industries, such as automotive, industrial, medical, telecommunications, aerospace, and defense.

Working principle

A film capacitor works on the principle of dielectric absorption. The material used as the dielectric between the two electrodes (aluminum plates in the case of the MKT1820415106) is positively charged on one side and negatively charged on the other. This charge is stored in the dielectric film and is released when the capacitor is subjected to an electric field. The amount of charge released is proportional to the dielectric strength and the electric field.

The MKT1820415106 employs a number of innovative technologies, such as high ripple current capability, bottom terminals for improved board density and greater mechanical strength, and an epoxy-encapsulated case for increased resistance to mechanical shock.

In conclusion, MKT1820415106 film capacitors offer a broad range of features and benefits, making them ideal for a variety of applications. They are highly reliable and offer excellent performance characteristics, making them one of the most popular types of capacitors among manufacturers.
