Description of the MKT1820447064 Film Capacitors

The MKT1820447064 is a type of film capacitor that falls into the broad category of general-purpose capacitors. It is created using polypropylene material, and its maximum working voltage is 1,500 volts. This film capacitor has several defining features that distinguish it from other capacitors. The physical characteristics, applications, and working principles that make the MKT1820447064 so useful are explained in more detail below.

Physical Characteristics

The MKT1820447064 film capacitor physically measures 18 mm in length and 20 mm in diameter, making it quite compact. It has a parallel-tabbed design that allows for easy and secure mounting into boards, and each capacitor has a total capacitance of 4.7 µF (+/-10%). Because of its parallel design, the self-inductance of the electrical circuit that it is part of is minimized, which helps improve circuit power.

Applications

The MKT1820447064 is commonly used in the field of switching mode power supplies, as well as in power filters. These film capacitors are used to address power-related problems, as poor waveform, excessive noise, and high losses are common in power electronics. Other common applications for the MKT1820447064 include electric circuits that require either small size or high frequency, such as flying-capacitor circuits for DC/DC converters or resonators for high-frequency applications.

Working Principle

To understand the working principle of the MKT1820447064 film capacitors, one must understand the concept of a capacitor in general. A capacitor is an electronic device that stores energy in the form of an electric field, essentially acting as a kind of mini battery. This field is then used to carry current within a circuit. The MKT1820447064 operates in a similar way, charging up and storing energy and then releasing it back into the circuit as needed.

The MKT1820447064 capacitor has a polypropylene film dielectric, which acts as the main insulator to ensure that the current only flows in one specific direction. This dielectric also serves to prevent electrical leakage and interference. Furthermore, the capacitor also has embedded aluminum foil electrodes that collect the charge and distribute it across the circuit when required.

When a voltage is applied to the MKT1820447064 film capacitor, the electric field between the parallel set of electrodes immediately begins to build up. This current then works in tandem with the dielectric to create the capacitor’s stored electric energy. From there, the capacitor can release the stored energy back into the circuit as needed.

Conclusion

The MKT1820447064 is an incredibly useful film capacitor, due in part to its compact size and wide range of applications. In addition to its physical features, the working principle of the MKT1820447064 describes how this device takes in and stores electrical energy when connected to a circuit. The stored energy can then be released back into the circuit when it is needed.
