Film capacitors are electronic components used to store electrical energy in an electric field. They are popular in a variety of applications due to their high capacitance and low leakage current. The 155PPA700K is a film capacitor specifically designed for general-purpose use. Its properties make it well suited for AC use, motor speed control, power supplies, and other applications.

The 155PPA700K has an operating temperature range of -55 to +85°C, a capacitance of 0.7μF~10.0μF, and a nominal working voltage of 275VAC. It has a 40/105/56 metric size and a connection type of either axial or radial. Furthermore, it is RoHS compliant and UL certified.

Film capacitors such as the 155PPA700K have three primary components – the film dielectric, the steel electrode, and the optical wrap. The film dielectric is a thin sheet of polyester or polypropylene film coated with electrically conductive material. The steel electrode is made from steel or stainless steel plates. The optical wrap is a sheet of PVC or polypropylene film tightly wrapped around the film dielectric and steel electrode.

The working principle of the 155PPA700K is relatively straightforward: it stores energy in an electric field. When a voltage is applied to the capacitor, an electric field is created between the two electrodes. This field draws in electrons, which accumulate on the inner electrode and create a static charge. When the voltage is removed, the field collapses and the electrons are released, causing the capacitor to discharge. This is how the capacitor stores and transfers energy.

The 155PPA700K is a highly reliable film capacitor that is well suited for general-purpose use, motor speed control, power supplies, and other applications. Its operating temperature range, capacitance, and nominal working voltage make it a versatile component for a variety of applications. With its high capacitance and low leakage current, the 155PPA700K is an ideal choice for any electronic project.
