Film Capacitors have found an important place in modern electronic equipment. This article will explain the application field and working principle of the typical film capacitor, ECQ-E12153JE.

A film capacitor is a type of capacitor that consists of one or more thin film layers of a dielectric material deposited on a substrate. The back plate can be made of an electrode material such as copper or aluminum. In the ECQ-E12153JE, the dielectric is a polyester film.

Film capacitors can be used in a variety of applications. One of the most common applications is in the high-frequency suppression of circuits. Film capacitors are useful because they provide a relatively low equivalent series resistance (ESR). This means that they can reduce the amount of high-frequency noise in the circuit. Additionally, they can provide surge protection when placed across the power supply lines.

Film capacitors can also be used in audio circuitry, such as amplifiers, equalizers, and loudspeakers. They can reduce cross-talk and provide an improved acoustic response. Film capacitors can also be used in motors and generator, as well as in LED lighting systems.

The ECQ-E12153JE has an operating voltage of 250V AC, and a capacitance range of 0.15 to 2.20uF. The tolerance is ±5%. The maximum working temperature is 85°C.

The basic working principle of a film capacitor is similar to that of any other capacitor. When a voltage is applied to two conducting surfaces separated by a thin layer of dielectric material, it causes electric charges to accumulate on the surface of the dielectric. This creates an electric field between the two plates. The larger the electric field, the larger the capacitance.

The current rating of the ECQ-E12153JE is 10A. This means that it can handle up to 10 amps of current without being damaged. The ripple current rating is also 10 amps. The ripple current rating is the amount of current that the capacitor can handle over a period of time without experiencing a decrease in capacitance.

The ECQ-E12153JE has an insulation resistance of greater than 10000MΩ. The insulation resistance is a measure of how well a capacitor can reject unwanted electric signals from other components in the circuit. The higher the insulation resistance, the better the performance of the capacitor.

The ECQ-E12153JE also has a low dissipation factor. This is a measure of how much energy is lost when the capacitor is in use. The lower the dissipation factor, the lower the level of energy wastage.

In summary, the ECQ-E12153JE is a film capacitor that can be used in a variety of applications. It has a high working voltage and a high insulation resistance. It also has a low dissipation factor, making it an ideal choice for applications where energy efficiency is required. Additionally, its low ESR means that it can reduce high-frequency noise and provide surge protection when placed across the power supply lines.
