Film capacitors, also known as film dielectric capacitors, are a type of capacitor consisting of two metal electrodes and a thin dielectric film material sandwiched between them. They are usually used in electrical or electronic circuits to store energy, increase voltage, reduce current, create filters, or provide signal time delays. The SFA66S4K288B is a type of film capacitor that is specifically designed for high voltage, high-current applications.

Application Field of SFA66S4K288B

The SFA66S4K288B is a four-quadrant, quad-section film capacitor designed for applications that require high voltage, high current, and high capacitance. It is ideal for use in high-voltage industrial power applications, such as motor control, power factor correction, and other high-voltage power supplies. It is also well suited for use in AC power line filters and wave filters, and other similar applications. The SFA66S4K288B is also certified to EN60384-21 and UL 1283 standards.

In addition, the SFA66S4K288B is suitable for use in radio frequency (RF) applications such as radar, telecommunication, and other RF electronic circuits. It is also ideal for use in audio and acoustics, as it reduces unwanted noise and provides improved signal clarity. The SFA66S4K288B is designed to operate in temperatures ranging from -40°C to +85°C, and is available with a voltage rating up to 10KVAC.

Working Principle of SFA66S4K288B

The SFA66S4K288B film capacitor works on the same principle as other types of capacitors. It consists of two metal electrodes separated by a dielectric layer of plastic or paper. When a voltage is applied across the capacitor, a small electrical charge will accumulate on the electrodes of the capacitor, which will cause the stored energy to increase. The capacitance of the capacitor is determined by the size and type of dielectric material used, as well as the area of the electrodes.

The SFA66S4K288B is designed with a four-quadrant, quad-section construction, which provides improved performance when compared to other types of capacitors. This capacitor also has a high maximum operating voltage rating of 10KVAC, which allows it to dissipate higher levels of voltage without becoming damaged. In addition, the SFA66S4K288B also has a high power dissipation capability, which allows it to provide a higher level of performance in applications where power consumption is important.

The SFA66S4K288B is also highly reliable, providing a long service life that is designed to withstand thousands of thermal cycling and repetitive over-voltage events without degrading in performance. Its high-temperature rating of up to +85°C allows for reliable operation in extreme conditions. In addition, it is also RoHS-compliant, meaning that it is free of any hazardous materials, and is safe for use in a variety of industrial and commercial applications.
