MKP385475025JFI2B0 Datasheet/PDFFilm capacitors, or plastic film capacitors as they\'re sometimes known, are versatile and cost-effective solutions for many types of electronic applications. MKP385475025JFI2B0 is an example of a film capacitor, and comes with a range of properties. This article will explain the range of application fields and working principles of this type of capacitor.
Application Fields
Film capacitors have been used for a range of applications including AC power applications, power factor correction, high voltage protection, radio frequency shielding and signal noise reduction. MKP385475025JFI2B0 is an organic polypropylene film capacitor that is well-suited for use in AC power supplies such as line-filter for switching power supplies, AC motors, and UPS systems. It also has a resistance to self-heating technology that enables the use of higher load current. Also, it has excellent temperature characteristics, making it suitable for use in temperatures between -25 and +85 degrees Celsius.
Film capacitors also have good use in signal-processing applications. They have a low leakage current, making them ideal for use in filtering applications in high-end audio amplifiers and audio processing systems. They also have a relatively low ESR/ESL ratio, making them effective at reducing noise when used in high frequency switch-mode power supplies. They\'re also highly reliable with a long useful life, so they can be used in demanding applications such as defense systems.
Working Principle
The working principle of film capacitors is quite simple. At the most basic level, they\'re composed of two conductive surfaces separated by an insulating dielectric layer. This dielectric layer is the plastic film which acts as an electrical insulator and prevents the current from leaking out into the atmosphere. The dielectric layer can also be made from different materials, such as ceramic or polypropylene, which can provide a variety of characteristics.
When voltage is applied to the capacitor, an electric field is created across the dielectric material. This field causes an electric current to flow between the two conductive surfaces. This current is then stored in the capacitor and can be released when the voltage is no longer applied. This allows the capacitor to act as a charge storage device and, if the capacitor is connected to an electronic circuit, it can be used to filter signals or to filter out noise.
Conclusion
The MKP385475025JFI2B0 is an example of a film capacitor and comes with a range of properties. It is a very versatile device and can be used in a variety of applications ranging from AC power supplies to high-end audio processing systems. The working principle of film capacitors is relatively simple – an electric field is created across the dielectric material which causes an electric current to flow between the two conductive surfaces. This current is then stored in the capacitor and can be released when the voltage is no longer applied. This makes film capacitors an excellent choice for many applications.
