Film capacitors, also known as film dielectrics, are a type of capacitor that use thin layers of plastic film, such as polyethylene terephthalate (PET), as the dielectric material to store an electrical field. The B25835T2224K7 is a classic example of this type of capacitor, and is often used in power supplies, signal filtering, and high frequency applications.In this article, we will take a closer look at the B25835T2224K7, its application field, and its working principle.The B25835T2224K7 is a type of axial lead film capacitor, which means that it has two metal leads along the long axis of the package. It is designed for use in a variety of general-purpose applications, such as signal filtering, timing, snubbing, AC line-by-passing, resonant circuit applications, and as an operating capacitor in power supplies.When used in signal filtering, the B25835T2224K7 can provide a low-pass filter which minimizes or eliminates noise components and high frequency interference. This design also allows for precise attenuation of AC signals, which is ideal for signal processing applications.The B25835T2224K7 also has a low impedance and high current carrying capacity, which makes it ideal for use as a timing capacitor in tuned oscillator circuits. It is also suitable for snubbing applications, where it acts as a surge absorption device, providing damping of inrush currents and voltage spikes.Finally, the B25835T2224K7 is an ideal choice for bypassing AC line voltages, which can help to reduce power dissipation in a power supply. In this type of application, the capacitor creates an RC filter network, which acts as a low pass filter and helps to reduce high frequency interference.In terms of its working principle, the B25835T2224K7 uses an extremely thin plastic dielectric film, such as PET, which is tightly rolled to create two metal foils on the inside and outside. These two metal foils act together as a capacitor, and store electrical energy. When a voltage is applied to the capacitor terminals, a current is created which accumulates on the metal foils, creating a field. This electric field creates a force that creates a compression force, which counteracts the force of the voltage applied to the capacitors terminals. The positive and negative charges accumulate oppositely on the metal foils, which helps to minimize any dissipation of the stored energy.To sum up, the B25835T2224K7 is a versatile film capacitor which is suitable for a variety of applications, such as signal filtering, timing, snubbing, and AC line-by-passing. It has a low impedance and high current carrying capacity, and utilizes a unique plastic dielectric film which helps to store energy without any dissipation.
