Film capacitors are capacitors that use a dielectric made of a thin film. These capacitors offer reliable performance, low equivalent series resistance (ESR), extended operating temperature range, small case size and high performance levels, making them suitable for a large range of applications. Among many of these capacitors, ECW-F2W395JA capacitors stand out due to being among the most advanced capacitors released in the market. In this article, we will explore the application field and working principle of the ECW-F2W395JA capacitors.The ECW-F2W395JA capacitors are generally used for applications that require a large amount of power and high switching speeds, such as power supplies, inverters, motor control, ballasts, and measuring systems. They enable smooth current interruption, meaning that they reduce overshooting voltages or switching surges from the switching noise. In other words, they guarantee improved operation efficiency, even at high frequencies. Moreover, the low ESR of these capacitors ensures high ripple current capability, reducing the amount of energy lost to heat. They also reduce the amount of audible noise, providing improved performance and protection.In terms of working principle, the ECW-F2W395JA capacitors are Polyphenylene Sulfide (PPS) dielectric with a metalized construction. This is achieved by depositing a thin, highly conductive metal film onto one side of the capacitor, typically comprised of aluminum. The PPS dielectric is then placed between the metal film and the capacitor’s remaining electrode. This metalized design helps to prevent dielectric breakdown, enabling higher small-signal max-currents. Additionally, the PPS dielectric provides superior performance in terms of voltage, leakage, temperature, and capacitance stability. In terms of capacitance stability, the ECW-F2W395JA capacitors offer great advantages in high temperature or high humidity environments. This is due to the fact that PPS materials have low temperature drift and low humidity dependency. The operating temperature range of the ECW-F2W395JA capacitors can range from -55°C to +125°C, making them a popular choice for mission-critical or industrial applications.Apart from their excellent performance, the ECW-F2W395JA capacitors also come in a very small package size, offering manufacturers more flexibility when choosing components for the designs. They are also lead free and RoHS compliant, meeting the standards of the European Union. All in all, the ECW-F2W395JA film capacitors are excellent components with an array of features that make them highly desirable for a number of different applications. From their reliable performance with low ESR, extended temperature range and ultra-small package size, to their superior capacitance stability and RoHS compliance - these capacitors are a great choice for high frequency applications requiring a high level of performance.
