Film Capacitors Overview

Film capacitors, also known as plastic capacitors, are a type of capacitor made of plastic film. These capacitors are an important component of power electronics and radio-frequency (RF) electronics applications. Film capacitors are well known for their low impedance, high temperature stability, low leakage current, low inductance, and stable capacitance values.

In many cases, film capacitors are used in place of ceramic or electrolytic capacitors. This is because they offer several advantages over their ceramic or electrolytic counterparts, such as higher capacitance, smaller size and ease of mounting. Additionally, their low cost makes them a more attractive choice than electrolytic capacitors.

ECW-U4272V17 Application Field and Working Principle

The ECW-U4 272V17 is a film capacitor primarily used in high frequency power electronics applications. This capacitor is made of a polypropylene film and is rated at a maximum working voltage of 272V. The ECW-U4 272V17 has a capacitance range from 47pF to 3300pF and is RoHS compliant.

In this type of capacitor, the built-in capacitor elements are arranged one after another, and then both ends are connected and installed into a metallized plastic film case. The basic working principle of this type of capacitor is based on the principle of electrostatic capacitance. This capacitance is created when two electrical conductors are separated by an insulating material. The insulating material is the film in this case.

The ECW-U4 272V17 has a very low equivalent series resistance (ESR) and is capable of operating at frequencies up to 1 MHz. This makes it ideal for high frequency power electronics applications, such as motor control, power conversion, inverters and switching power supplies.

The ECW-U4 272V17 film capacitor is also ideal for RF applications, such as signal filtering and signal matching. These film capacitors also offer excellent high frequency performance, with minimal signal attenuation. Additionally, these capacitors are designed to provide a low insertion loss, which makes them perfect for applications with high signal integrity.

With the low ESR and excellent high frequency performance, the ECW-U4 272V17 film capacitors are ideal for a variety of power electronics and RF applications. Additionally, the small size and RoHS compliant design of the ECW-U4 272V17 makes them an attractive option for many applications.
