255PSB122K2R

Film capacitors are a type of capacitor used to store electric potential energy for both alternating current (AC) and direct current (DC). They consist of a thin film of metal or plastic coated onto a flat substrate, and can be used in a variety of high current applications, including AC motors, power supplies, and switches. The 255PSB122K2R is a type of film capacitor that is a great choice for many applications.

The 255PSB122K2R film capacitor is a radially leaded, 275 VAC bi-polar polyester capacitor. It is designed to offer reliable performance in high DC currents, providing excellent storage capacity and temperature stability. It is rated for an operating temperature range of -25 °C to +85 °C, making it suitable for use in a wide variety of environments. It also has a low ESR rating, making it efficient for high current applications.

The main applications for the 255PSB122K2R film capacitor include AC motor control, lighting ballast control, power supply regulation, and switching applications. It can also be used for low-frequency AC line filtering, line- and load-side AC circuits, and automotive applications. The capacitor is highly reliable in all the stated applications – it is designed to withstand the harsh environment typical in many of these applications.

The working principle of the 255PSB122K2R film capacitor is relatively simple. It consists of two or more electrodes made of metal and a thin insulating material (typically a plastic film such as polypropylene). The electrodes are electrically connected to each other, and the insulating material is used to prevent them from shorting out. In operation, an AC voltage is applied to the electrodes, which causes the capacitor to store the energy in the form of a field between the electrodes. As the voltage levels change, the current passing through the capacitor also changes, causing the capacitor to release or absorb the stored energy as needed. Thus, film capacitors can act as both a source and a sink for electrical energy, making them versatile and reliable components for a wide range of uses.

In summary, the 255PSB122K2R film capacitor is an excellent choice for high current applications, offering reliable performance, a wide temperature range, and a low ESR rating. It is used primarily in AC motor control, lighting ballast control, power supply regulation, and switching applications. The working principle is that of a simple capacitor, in which two or more electrodes are connected to a thin insulating film that store and release electrical energy as required.
