Film capacitors, also known as film dielectric capacitors, are passive electrical components that store energy in the form of an electric field. The dielectric material in a film capacitor is a thin polymer film with a very small thickness and a very high dielectric constant. This type of capacitors holds advantages over other types of capacitors in terms of stability, reliability, low ESR and more.

The ECW-H12223JL film capacitor is a polyethylene-terephthalate (PET) dielectric capacitor that is typically used in high voltage DC applications. It offers a range of values from 0.22uF to 47uF and a capacitance tolerance of ±10%. The voltage rating for this series of capacitors is 850VAC and the operating temperature range is -30°C to +85°C.

Application Field

ECW-H12223JL capacitors are typically used in high voltage DC applications such as induction motors, wind turbines, medical instruments, industrial control, power supplies, and more. These capacitors can be used in applications with an operating frequency range from 10Hz to 10kHz. Its excellent low-loss performance makes it ideal for filtering AC ripple currents.

Working Principle

The working principle of the ECW-H12223JL film capacitor is essentially the same as any other type of capacitor; two conductive plates separated by a dielectric material. The dielectric material is typically a very thin, extremely durable film. This film is engineered to have a very high dielectric constant, which allows it to store a large amount of energy in a very small space. The two plates act as a capacitor, and the amount of energy stored is proportional to the area of the plates and the thickness of the dielectric material.

The ECW-H12223JL capacitor is constructed from a polyethylene-terephthalate (PET) dielectric material with a very thin thickness and a very high dielectric constant. The plates are typically made of aluminum foil with very thin layers of PET insulation to reduce contact resistance and ensure a reliable connection. The two plates are then connected to the connecting terminals and a sealed cover is placed over them to protect them from the elements.

The ECW-H12223JL capacitor is highly efficient and reliable due to its low ESR, high operating temperature range, and long life expectancy. When subjected to extreme temperatures, the dielectric material maintains its dielectric properties, making it an ideal choice for applications operating in harsh environments.

The ECW-H12223JL film capacitor is a highly reliable and efficient capacitor solution for high voltage DC applications, and it offers a range of values from 0.22uF to 47uF and a capacitance tolerance of ±10%. Its excellent low-loss performance and wide operating temperature range make it an ideal choice for applications such as induction motors, wind turbines, medical instruments, industrial control, power supplies, and more.
