Film Capacitors

Film capacitors are a type of capacitors typically designed using plastic films as dielectric insulation, and metal layers as conductors. The MKT1818410016 model is one such capacitor, and has a number of attractive features.In terms of its application field, the MKT1818410016 is utilized in fields such as automotive electronics, industrial electrical and power electronics, communication and lighting control. This is because of its high-intensity capacitance and relatively low equivalent series resistance (ESR). Furthermore, its high stability and long-term reliability make it suitable for various harsh environments.The capacitor is widely used as an AC or DC filter capacitor or high-frequency coupling and decoupling capacitor, giving it flexibility in a range of applications. Additionally, the MKT1818410016 has excellent heat and humidity resistance, and due to its low ESR, can operate at frequencies up to 1M Hz.

Working Principle

The MKT1818410016 capacitor utilizes a film as the dielectric insulation, thus creating a dielectric layer between the two conducting plates. This allows it to withstand heavy current loads as well as high DC voltage levels.The capacitor also incorporates metalized electrodes, which are augmented with a layer of metallized material to fine-tune the capacitance value of the capacitance. This is achieved by changing the thickness of the dielectric, and thus changing the capacitance value.To create the capacitance, an AC current is applied to the MKT1818410016 and an electric field is created between the two conducting plates. This electric field creates an electrostatic field, which allows for the attraction of charges from one plate to the other and thus, giving the device it’s capacitance.Since the MKT1818410016 capacitor utilizes plastic films as the dielectric, the device has extremely high insulation resistance which prevents the capacitor from generating sparks or arcs. The device is also thermally stable, meaning it is able to handle substantial temperature changes without any reduction in capacitance performance.
