Film capacitors are electronic components that are used in a wide variety of applications. They are frequently seen in audio and video equipment, home appliances and computers, and have recently found increased applications in telecom and broadcast equipment. In this article, we will examine 890303428008CS application field and its working principles.

Film capacitors are versatile components that can be used in a variety of applications. The 890303428008CS is of particular interest due to its ability to provide effective low-frequency filtering and signal-conditioning capability. It is also useful in power supplies where it can be used to reduce the ripple in the DC output. In addition, it is commonly used in radio frequency (RF) applications for its excellent RF suppression characteristics.

The 890303428008CS is a AC film capacitor with a capacitance range from 100pF to 10uF. It has a maximum operating voltage of 200V, a rated power of 0.1W and a temperature range of -25 to +85 degrees Celsius. It is rated for ripple current of up to 80mA rms and has a dielectric loss factor of 0.025. Its package size is 5mmx7mm, with a total height of 11.5mm. The 890303428008CS is UL approved and meets RoHS directives.

The 890303428008CS utilizes a combination of film technologies, employing a different thickness and composition of dielectric layers, which gives it its high endurance and other special characteristics. The high thermal resistance makes it suitable for applications where dissipating heat may be an issue. The dielectric layer is typically composed of polyester, polypropylene, aramid fiber and paper, depending on the specific application requirements.

The working principle behind the 890303428008CS is based on Faraday’s law of inductance. When an electric current is passed through a metallic conductor, a magnetic field is generated. This magnetic field will induce eddy currents in the conductor which, in turn, will create opposing magnetic fields. The opposing magnetic fields react with the applied electric field, creating an electric field that is 90 degrees out of phase with the applied field. This interaction decreases the current through the coil, resulting in a reduction in inductance. By varying the thickness, composition, number and type of dielectric layers, different levels of capacitance and inductance can be achieved. When two dielectric layers are used in series, the total capacitance is the sum of the individual capacitances of both layers.

The 890303428008CS film capacitor is an excellent choice of component for RF applications, due to its high linearity and consistent performance at high frequencies. Its package size also makes it suitable for applications where size is a major factor. It is ideal for low-frequency filter and signal-conditioning circuits, as well as power supplies and RF suppression applications. With its excellent endurance and high thermal resistance capabilities, the 890303428008CS makes a great choice for a variety of electronic applications.
