Film capacitors, also known as film dielectric capacitors, are capacitors which use a film as a dielectric material. These capacitors are based on the use of thin flexible films such as paper, plastic, or metalized films, with or without metal electrodes. The film dielectric is typically used to provide stability and flexibility to the capacitor by altering the dielectric strength, ESR, and impedance of the capacitor. Common applications include power electronics and quality filter capacitors.

890283327010CS application field

Film capacitors are widely used in various types of power electronic and electronic circuits. They provide improved frequency response, low ESR and operate at higher temperatures in comparison to other types of capacitors. Film dielectric capacitors offer excellent properties such as higher dielectric strength, lower dielectric losses and improved thermal and surge performance. They are ideal for power supplies, motor controls, AC induction motors, stepping motor drives and control circuits. Film capacitors are also used in the automotive industry, for automotive and aerospace applications.

890283327010CS working principle

The 890283327010CS operates on the principle of a capacitor-like structure consisting of two spaced apart electrodes with an insulating material between them. The electrodes are usually made of a highly conductive, low-resistance metal such as aluminum or copper-alloy. The dielectric can be air, mica, polyester, polypropylene, polystyrene, polycarbonate, etc. The electrodes are connected to the external contacts of the capacitor. When a voltage is applied to the terminals of the capacitor, an electric field is generated between the two electrodes that stores an electrical charge.

The most important parameters of the 890283327010CS are its capacitance, working voltage, maximum ripple, series resistance, leakage current, dielectric absorption ratio, and temperature rating. The capacitance is the ability of the capacitor to store electric energy and is measured in Farads. The working voltage is the maximum voltage the capacitor can withstand without heat damage or insulation failure. Maximum ripple current is the greatest instantaneous alternating current (AC) that can pass through the capacitor in a steady state. Series resistance is the internal resistance of the capacitor that determines the effective current levels of the device. Leakage current is the current that passes through the capacitor when the voltage is applied and it is typically very low.

The dielectric absorption ratio of the 890283327010CS is a measure of the capacitor’s ability to retain its capacitance over a long period of time, even when voltages are applied intermittently. The temperature rating of this type of capacitor is typically between -40°F (-40°C) and +225°F (107°C). The 890283327010CS is designed to be self healing, so if the dielectric material breaks down due to overvoltage or other stress, the capacitor will automatically restore its capacitance.

In conclusion, the 890283327010CS is a high performance film dielectric capacitor ideal for power electronic, automotive, and aerospace applications. It provides excellent stability, high dielectric strength, low ESR, and temperature ratings. It is important to take into consideration the various parameters such as capacitance, working voltage, maximum ripple, series resistance, leakage current, dielectric absorption ratio and temperature rating when deciding the right capacitor for your application.
