Film capacitors refer to capacitors with a dielectric made of plastic film. They use a thin plastic film separator to form multiple layers of metal foil capacitors, which are connected in parallel. 155PPB250K is one of the series of film capacitors. This series of capacitors has a rated voltage of 250V, a capacitance value of 0.1~1000μF, and an insulation resistance of more than 3000s when measured at 25 °C. Film capacitors have many advantages over other types of capacitors. First, they have higher voltage ratings and higher insulation resistance. This makes them ideal for use in high-voltage applications. Second, they are highly stable and reliable, making them suitable for a wide range of applications. Finally, their compact size makes them well-suited for applications where space is limited.The working principle of a 155PPB250K film capacitor is the same as that of all other types of capacitors. When a voltage is applied across the capacitor, the electrical field causes electrons to be displaced from one side of the capacitor to the other. This displacement of electrons creates an electric charge which is stored in the capacitor. When the applied voltage is removed, the stored charge is slowly released, restoring the capacitor to its original state.One of the primary applications of the 155PPB250K series of film capacitors is for motor power supply filtering and electric vehicle (EV) charging circuit filtering. They can be used in motor power supplies and EV charging circuits to filter out any noise or spikes in the power supply, allowing for cleaner, more reliable power. This is important in order to protect the sensitive motors and other components in the system.Another application of the 155PPB250K series of film capacitors is the field of digitally reinforced audio (DRA). DRA is a type of audio technology that uses digital signal processing (DSP) to modify the sound of an audio signal. It is sometimes used in recording studio and live concert settings. The use of a high-quality film capacitor in the DRA system is important in order to eliminate any unwanted noise or distortion.Finally, the 155PPB250K series of film capacitors can also be used in automotive applications. In particular, they can be used in noise suppression circuits in cars, which are designed to reduce the amount of external noise and interference entering the audio system. This is important for providing clear and uninterrupted audio playback.In summary, the 155PPB250K series of film capacitors is used in a wide range of applications, including motor power supply filtering, EV charging circuit filtering, DRA, and automotive noise suppression. Their high voltage rating and high insulation resistance make them ideal for use in these applications, and their compact size makes them well-suited for applications where space is limited.
