Film Capacitors
Film capacitors, also known as plastic film capacitors, are plain capacitors that are typically composed of polyester, polycarbonate and polypropylene film. These capacitors are wound together with two metal electrodes, and the capacitance is determined by the proportion of the area of the film material and the spacing between the electrodes. The electrical properties of film capacitors vary depending on the type of material used in the capacitor.
ECQ-U2A394MV Application Field and Working Principle
ECQ-U2A394MV film capacitors are widely used in a variety of applications such as AC line filtering, power factor correction, and transient voltage suppression. This type of capacitor is designed for low-power AC filter applications and features an AC voltage range from 70 VAC to 500 VAC. Its capacitance ranges from 0.02 uF up to 4.7 uF. With a maximum operating temperature of 105 Celsius, the ECQ-U2A394MV has a low ESR of 0.0015 ohms and a temperature coefficient of 0.25%.
The ECQ-U2A394MV utilizes a metalized polypropylene film dielectric. The metalization process allows for increased attenuation due to the higher loss of energy when the metalized dielectric is subjected to an electrical field. This increased loss of energy provides better AC filtering abilities and high frequency noise rejection.
The ECQ-U2A394MV is self-healing which enables it to momentarily short circuit and automatically recover without causing any damage to the capacitor. This type of capacitor also offers high surge capabilities and can handle frequencies up to 10 kHz without any loss in performance.
The ECQ-U2A394MV also features a full metal jacket which prevents any foreign objects from entering or affecting the capacitor’s performance. This casing is designed to safely contain the capacitor’s internal parts and protect them from any external interference. Additionally, the casing also helps reduce the effects of electronic noise which can degrade capacitors’ performance.
Overall, the ECQ-U2A394MV film capacitor is a reliable and efficient component for AC filter applications. It offers a combination of low ESR, high surge capabilities, and self-healing technology, making it an excellent choice for providing reliable and efficient power filtering.
