Film capacitors are a widely used form of capacitor, ideal for many electric and electronic applications, especially those where stability, reliability, and long life are important factors. The ECQ-E4155JFY is a high-grade film capacitor, designed to meet the demands of a wide range of industries. This article describes its application field and working principle.

The ECQ-E4155JFY is primarily used in medium- to high-voltage power electronics, such as filters, snubbers, decoupling, and power supply capacitors. It offers excellent performance in terms of excellent electrical characteristics, insulation characteristics, ripple current performance, and life expectancy. The ECQ-E4155JFY provides a high rated voltage of 10kV, with a voltage range of 0.25kV to 10kV, an insulation resistance of >10GΩ • μF, and a capacitance range of 0.47μF to 330μF.

The ECQ-E4155JFY is a high-quality film capacitor with excellent performance characteristics and a long lifespan, perfect for many electronic applications. It features a variety of capacitance values, high closed-circuit voltage, low equivalent series resistance (ESR), and temperature stability. The ECQ-E4155JFY also has a wide temperature range of -40°C to +125°C, making it suitable for many operating environments.

The ECQ-E4155JFY has a dielectric film made of polyethylene naphthalate (PEN). This film is highly reliable and durable, providing insulation and long-term stability. The capacitor is also designed to withstand a wide temperature range and high currents. It provides excellent capacitance stability, including over time, temperature, and applied voltage.

The working principle of the ECQ-E4155JFY is based on the classic electrostatic Charge-Discharge theory. This theory states that when two plates of a capacitor are charged up with opposite signs of static electricity, a potential difference is developed between them. This electrical field then stores the energy in the form of static electricity for the capacitor, which can then be released when needed. The ECQ-E4155JFY uses an interdigitized dielectric film as the charge-discharge element, allowing for very low ESR and high capacitance values.

The ECQ-E4155JFY is an excellent choice for a wide range of applications, including power conversion systems, high-voltage filters, snubbers, decoupling, and power supply capacitors. Its ability to withstand a wide temperature range, high capacitance values, and low ESR makes it one of the most reliable and versatile film capacitors on the market today.
