205PMB122KN

Film capacitors, also known as plastic film capacitors, are electronic components that store energy by means of electric fields. They are similar to electrolytic capacitors, but they use dielectric materials such as polyester or polypropylene materials to achieve their capacitance. Film capacitors are known for their excellent performance and reliability and are widely used in a variety of electronic devices.

The 205PMB122KN is a polypropylene film capacitor designed specifically for power supplies and noise filtering applications. It has a voltage rating of 200V and a capacitance of 2.2μF. The dielectric material provides excellent insulation resistance and is capable of withstanding high temperatures. Additionally, the capacitors are designed to be ultra-low ESR, which provides superior frequency characteristics.

The working principle of the 205PMB122KN is based on a dielectric material between two conductive plates. These plates act to conduct current and charge the capacitor until the capacitor reaches its breakdown voltage. As the voltage increases, the dielectric material gets closer and closer to the current flow, effectively increasing the capacitor’s capacitance. When the capacitor is charged, the current flow is stopped and the voltage remains constant.

The 205PMB122KN is typically used in power supplies, noise-filtering applications, hot-plug circuits, and switching applications. It has become a widely used choice in a variety of power supply designs due to its low ESR and excellent high-frequency characteristics. Its wide operating temperature range makes it an ideal choice for high-reliability applications such as automotive electronics. It is also suitable for applications which require high capacitance, low losses, and high thermal endurance.

The 205PMB122KN is a high-performance film capacitor with excellent characteristics that make it suitable for a variety of applications. It is capable of withstanding high temperatures and provides superior performance and reliability. Its low ESR and wide temperature range make it ideal for high-reliability applications and power source designs, making it a popular choice for a variety of power supply and noise-filtering designs.
