Film capacitors, also known as plastic film capacitors, are widely used in electronics, communication and computer products, as well as electrical and instrumentation devices. ECQ-E2273JF3, a film capacitor, has been widely used in LCD/LED displays, audio/visual products and power supplies. Its working principle is to store energy through the electric field between two electrodes, the dielectric material, metal foil and metal-plated electrodes treat each other as medium.

ECQ-E2273JF3 is a type of metalized polyester film capacitor with radial lead. Its application field focuses on the protection and de-coupling circuits of electronic equipment, medical and household appliances, electronic power control as well as various electronic instruments. Its features include small size (radial lead mode) and long life span related to its outstanding humidity and temperature resistance. ECQ-E2273JF3 has the characteristics of low cost, small size, low dielectric dissipation factor and high insulation resistance.

ECQ-E2273JF3 has a rated voltage of 16V and a capacitance value of 0.033uF. This film capacitor has a long life expectancy due to its outstanding heat and humidity resistance and has a good self-repairing ability. Additionally it also has high insulation resistance and low dissipation factor which makes it ideal for applications in which high frequency response is necessary. The capacitor operates by trapping and storing electric charge in an electric field applicated between two electrodes: the dielectric material, metal foil and metal-plated electrodes. When a voltage is applied, electric fields are generated, creating a capacitance which can be calculated by the equation C=εA/d, where ε is the permittivity of the dielectric material (The dielectric used in case of ECQ-E2273JF3 is Polyethylene Terephalate (PET) at a low temperature the permittivity of which is around 3.3-3.5).

In summary, ECQ-E2273JF3 is a metalized polyester film capacitor with radial lead and a type of film capacitor. Its application field focuses on the protection and de-coupling circuits of electronic equipment, medical and household appliances, electronic power control as well as various electronic instruments. Its features are small size with a capacitance value of 0.033uF, high insulation resistance, low dielectric loss, long life expectancy due to its outstanding heat and humidity resistance, and good self-repairing ability. Its working principle is to store energy through the electric field between two electrodes, the dielectric material, metal foil and metal-plated electrodes treat each other as medium.
