Film Capacitors

Film capacitors are a type of capacitors widely used in electronic circuits. They are made of plastic films and electrolyte. Film capacitors provide superior electrical insulation, reliable performance, good temperature characteristics and excellent longevity. The 155PMB122KFM8P0 film capacitor is one of the most popular film capacitors on the market, and its application field and working principle are discussed in this article.

Application Field

The 155PMB122KFM8P0 film capacitor can be used in many applications including power electronics, motor-driven control systems, high-capacity power supply, audio equipment, DC/DC power supplies, automotive electronics and industrial automation. It is commonly used as a part of a filter or bypass capacitor in power electronic devices. The energy storage capability of 155PMB122KFM8P0 film capacitor makes it suitable for use in this application field, where high voltage spikes, fast current changes and low-impedance conditions are present.

Working Principle

The 155PMB122KFM8P0 film capacitor is based on the capacitor principle, which states that two electrically-connected conductive plates separated by an insulating material form a field that stores electrical charge. When a voltage is applied across the capacitor’s plates, a current will flow until the capacitor is fully charged. The stored energy is held until the capacitor is discharged when the voltage is reduced or removed. The capacitance of the 155PMB122KFM8P0 film capacitor is determined by the size of the capacitor’s plates and the insulating material between them.

Film capacitors are designed for use in situations where a low-level voltage and high-speed current changes are present. Their high capacitance makes them useful in a wide range of applications such as AC electric motor speed controls, audio/video systems, and high-capacity power supplies. They offer excellent performance in terms of frequency response, temperature characteristics and long life.

The 155PMB122KFM8P0 film capacitor is ideal for use in power electronic devices, as it provides excellent electrical insulation. The capacitor is capable of storing high energy in a short amount of time, making it suitable for applications where high voltage spikes and fast current changes occur. The temperature characteristics of the 155PMB122KFM8P0 film capacitor are another advantage, as they ensure that the capacitor will perform reliably under a wide range of operating conditions.

In conclusion, the 155PMB122KFM8P0 film capacitor is an excellent choice for use in power electronic devices due to its high capacitance, superior electrical insulation, long life, and excellent temperature characteristics. Its application field ranges from AC electric motors to power supplies, audio/video systems, and other electronic devices.
