Film capacitors are very common in modern technology, having a broad range of uses and are frequently featured in electrical circuits. ECW-F4913HL is one of the newest additions to the film capacitor catalogue, offering a remarkable performance tailored to a variety of applications. This article will outline its applications and describe the underlying working principles of the capacitor.

The ECW-F4913HL is a polypropylene film capacitor with a copper-clad steel lead wire connection, designed for use in applications requiring high power and frequency. As a result, it is capable of being used in a variety of areas, such as in transistors, audio amplifiers, and power systems. This makes it an invaluable asset in the development of a variety of equipment and devices.

In terms of its construction, the ECW-F4913HL features a polypropylene film dielectric – the material that forms the electrical insulation between two conductors. This dielectric is laminated between two aluminium foil electrodes and surrounded by polypropylene film as a protecting shell. In addition to its outstanding mechanical strength, polypropylene provides high insulation resistance and excellent temperature characteristics.

The capacitive properties of the ECW-F4913HL ensure a low dissipation factor, resulting in an efficient and reliable operation in a variety of frequencies. This is particularly true for its work up to 10kHz, when it can offer an exceptional performance in a wide range of applications, both in terms of frequency and power. Additionally, its low leakage current ensures that it will not contribute to polarisation decay in oil-cooled applications.

To understand the basis for the ECW-F4913HL’s remarkable performance, it is important to understand the working principles of capacitors in general. All capacitors consist of two conductors – an anode and a cathode - separated by a dielectric material. When a potential difference is applied across the two terminals of the capacitor, an electric field is created, which causes a displacement of the ions in the dielectric. This displacement of charge creates an electric field which induces and stores an electric charge in the electrodes of the capacitor.

Although the ECW-F4913HL can be expected to return an excellent performance in general, it is important to take into account its temperature characteristics and mounting requirements. Although it can operate up to temperatures of 85°C, poor thermal heating management may damage it in the long run. Furthermore, its construction is particularly fragile and requires a considerable amount of care when mounting.

The ECW-F4913HL is an excellent addition to the catalogue of film capacitors, and is capable of outperforming many of its competitors. As a result, it is suitable for a range of applications requiring high power and frequency, offering excellent performances and reliability. All these functionalities, coupled with an affordable price point and great convenience, make it an ideal choice for a variety of devices and equipment.
