Film capacitors (also known as polystyrene capacitors) are unique in their ability to provide an extremely low-loss characteristic. This particular capacitor, the MKT1822422636, is an example of a film capacitor that offers exceptional performance for its small size. In this article, we will discuss the MKT1822422636’s application field and working principle.

Film capacitors have traditionally been used in audio applications. This is due to the fact that they possess excellent tolerance against frequency variation, making them seemingly immune to any distortion. As a result, film capacitors are perfect for applications such as tone control networks, or to provide the necessary taming of any frequency variation when constructing a filter circuit.

The MKT1822422636 from TDK is a film capacitor that provides a type of film dielectric that is specifically designed for high-temperature operation. It has a capacitance of 2.2 µF, a voltage rating of 250 VAC, and a temperature range from -55°C to 105°C, making it well suited for commercial and industrial applications. This particular capacitor also features a vibration-resistant structure, ensuring that its performance remains intact under extreme conditions.

In terms of working principle, the MKT1822422636 is designed in a standard EIA film capacitor construction. The capacitor consists of two metal electrodes that are applied directly to an insulating dielectric film. This ceramic layer provides excellent insulation from surrounding elements, allowing the capacitor to store electrical energy through capacitance.

The dielectric movement of electrons causes the metal electrodes to be charged with a current, while the capacitance value of the MKT1822422636 determines the amount of charge stored by the capacitor. The current stored by the capacitor is then discharged when there is a change in the neighboring charge field, making it possible to control electrical components with precise timing.

Despite its relatively small size, the MKT1822422636 film capacitor offers exceptional performance for its class. The dielectric film is optimized to provide an extremely low-loss characteristic, while the vibration-resistant structure ensures durability under extreme conditions. This makes the MKT1822422636 well suited for commercial and industrial applications, particularly in audio applications where high-frequency accuracy is essential.
