Film capacitors, also known as plastic film capacitors, are general types of capacitors composed of a thin plastic film insulator, such as polyethylene terephthalate (PET), polystyrene, polycarbonate, polypropylene, or polyvinylidene difluoride (PVDF). The film can be either metalized or constructed from a metal foil with a thin insulating film coating. The most common type of film capacitor is the MKT1822410256.

MKT1822410256 is a metallized polyester film capacitor type with radial leads. These capacitors offer low ESR and ESL, being self-healing and non-polar possibly supporting higher temperature. They provide good Energy storage capabilities, high ripple current capabilities and low voltage coefficients. Their temperature range varies from -55°C to +105°C with an insulation resistance of > 10000 MΩ up to +100V. The capacitance ranges from 0.0047uF to 100uF.

The MKT1822410256 application field is wide and includes consumer electronics, microwave ovens, lighting, computer and communication, digital audio, air conditioning, washer and dryer equipment, semiconductors, and machines for industrial purposes.

The working principle of an MKT1822410256 is straightforward and based on a simple rule of electricity: when voltage is applied across two conductors, a current flows. The two conductors form two plates, with the insulator acting as the dielectric material between them. The capacitance’s main job is to store charge, which creates an electrical field between the two plates. When the voltage across the plates is high enough, the field is strong enough to jump the gap between them. This is known as dielectric breakdown, and occurs in the form of an arc, creating a gap in the dielectric which disrupts the electrical field.

As we now know, MKT1822410256 is a metallized polyester film capacitor. The metalized layer is actually composed of several metalized layers of alternating metal conductive layers and insulating polymer, separated by a very thin film of insulating polymer. Therefore, the capacitance of the MKT1822410256 is determined not only by the plate spacing, but also by the amount of metal covering each plate. This allows for high capacitance from a relatively small case size.

The MKT1822410256 is a robust capacitor that can handle high ripple current and long life when operating in its temperature range. It has low ESR and ESL, allowing higher efficiency in energy storage applications. These capacitors are also self-healing, meaning they can recover from most shorts or dielectric breakdowns without needing to be replaced.

The MKT1822410256 is a versatile capacitor family that has a wide range of applications in consumer electronics, industrial equipment, and automotive electronics. With its wide capacitance range, low ESR, and excellent self-healing performance, the MKT1822410256 is an ideal solution for many types of power supply and energy storage applications.
