Film Capacitors

Film capacitors can be classified into polyester film capacitors and polypropylene film capacitors. The former has great popularity among many electronic products due to its low price, and the latter has strong capacitance and excellent anti-interference capability. Both film capacitors are widely used in electrical equipment and electronic products. For example, MKP1841480255 belongs to polypropylene film capacitor. This kind of capacitor applies the advantages of low inductance, low noise, and high-speed response in the applications, such as signal circuits and power supply filters.

Application Field

The MKP1841480255 film capacitor is an SMD type capacitor. Due to its small size, this product is used in a very wide field, such as audio amplifiers, power supplies, and various electronic products related to signal processing. It is also suitable for use in various DC circuits, such as power supply rectifier filter, DC smoothing, and pulse power supply filtering. It is also ideal for applications in AC circuits, such as AC smoothing, signal filtering, and anti-interference.

Working Principle

The working of film capacitors is based on the theory of capacitance. It consists of two electrodes, one of which is made of metal sheet and the other from a dielectric film, and an insulating paper as a separator. When voltage is applied to the two electrodes, a dielectric oxide film will be formed between them. This dielectric oxide film produces static electric field which can store a certain amount of energy. Therefore, the capacitor acts as a charge-storage device and can discharge and emit electricity instantaneous. This is probably the most important feature of the capacitor, which makes it useful in AC and DC circuits.

Furthermore, film capacitors have excellent features compared to other capacitors, such as paper capacitors, electrolytic capacitors, ceramic capacitors, and tantalum capacitors. They have low loss tangent, low-temperature coefficient, high-sensitivity, and high-working frequency. In addition to that, film capacitors are also miniaturized, lightweight, and more reliable and stable.

Conclusion

To sum up, the MKP1841480255 is a film capacitor that belongs to the polypropylene film capacitor. It has many advantages such as small size, low loss tangent, low-temperature coefficient, high-sensitivity, and high-working frequency. These advantages make it suitable for many applications, such as audio amplifiers, power supplies, signal processing, DC power supply filters, AC signal filtering, and anti-interference. Its working principle is based on the theory of capacitance and it acts as a charge-storage device that can store a certain amount of energy.
