505QPC250KB5A3L

Film capacitors, also known as polymer film capacitors, refers to a type of capacitor which utilizes a thin film of a non-conductive substance such as paper, polypropylene, polyethylene, polystyrene, each metalized on both sides with an electric conductor, as the dielectric. 505QPC250KB5A3L is a type of polymer film capacitor, with high capacitance and low ESR, which can be used to filter and decouple in industrial control, communications, and computer equipment. It’s also suitable for many application like energy-saving lamps, electric tools, power adapters and battery packs.

In particular, 505QPC250KB5A3L has a number of characteristics which make it suitable and reliable for many applications, such as accuracy, long life and stability. It offers a very low level of ESR and very high capacitance, and has the advantage to retain its capacitance over a wide temperature and voltage range. The working voltage ≤ 250V AC/DC and the capacitance can reach as high as 250KB5A3L.

Furthermore, it has good performance of self-healing property, which can prevent the capacitor from damaged or over pressured due to the over voltage or over temperatures. The self-healing property is a unique advantage of the polymer capacitors, compared to other types of capacitors, a feature which make them the choice for many power electronics applications.

The primary application area for 505QPC250KB5A3L is power electronics, which includes power supply, UPS, inverter and DC/AC converters. It can be used as a filter capacitor to prevent power line ripple from entering the load, by reducing the pollutant electromagnetic noises. As for its working principle, when the voltage is applied on two conductive plates of the capacitor, an electric field is generated in the dielectric material, leading to the accumulation of charge, and thus the formation of an electric field. This accumulation of charge causes an increased potential difference between the plates, and this potential difference is what is known as the capacitance.

In summary, 505QPC250KB5A3L is a reliable type of film capacitor with high capacitance and low ESR, suitable for many application like energy-saving lamps, electric tools, power adapters and battery packs. Its primary application is in power electronics, where it can be used as a filter capacitor to reduce the pollutant noise, and its working principle is based on the accumulation of charges created by an electric field.
