Introduction
Film capacitors featuring ECW-H16273JVB are polypropylene dielectric-film capacitors with metallized electrodes. Due to their low equivalent series resistance, high thermal stability and high insulation resistance, they are widely applicable in a variety of circuit designs. This article will focus on discussing ECW-H16273JVB application fields and working principle.

Classification as Film Capacitors
Film capacitors, also named as plastic film capacitors, are categorized as non-polar, dry-type capacitors fabricated with a thin plastic film as the dielectric. Specifically, ECW-H16273JVB is a very reliable polypropylene dielectric film capacitor that features low equivalent series resistance (ESR), high insulation resistance and wide temperature range, which leads to a longer cycle life and low intrinsic interference. As a result, ECW-H16273JVB can be classified as film capacitors.

Application Fields
ECW-H16273JVB capacitors are suitable for various applications, such as motor starters, coupling capacitors, AC line filters, harmonic filtering, converters, lighting, medical, communications, and instrumentations, etc. Among them, ECW-H16273JVBs are particularly applicable for motor starters due to their current-limiting, voltage-stabilizing and heating protection capabilities. This is critical in preventing reverse breakdown of the motor as well as protecting the motor from operating at excessively high temperature. ECW-H16273JVBs are also suitable in converters, AC line filters, and lighting, as they can provide high-frequency noise suppression and line filtering.

Working Principle
In order to understand the working principle behind ECW-H16273JVB, we have to firstly look into capacitor basics. Once electrical potential is applied onto a capacitor, current will be blocked and electrical charges will be stored in the capacitor’s dielectric, which is made of either air or ainsulator. When the same voltage is also applied on the other side of the capacitor, the charges stored in the dielectric interact with each other, and a build-up of charge occurs at each plate of the capacitor, creating an electric field between the two plates. Electric charges will then start accumulating and the voltage of the capacitor will be raised. The process of storing and supplying electrical charges is known as capacitance.

ECW-H16273JVBs highlight their features with a unique construction. The dielectric used in this type of capacitors is polypropylene,which is combined with metallized electrodes. By then, a precision winding process is required in order to ensure the parameters remain within the maximum tolerance. This is how ECW-H16273JVBs are meant to perform as a capacitor.

Conclusion
As a result, ECW-H16273JVB can be easily classified as film capacitors due to its high stability and wide applications. These capacitors are mainly applicable in motor starters for the purpose of current-limiting, voltage-stabilizing and heating protection, while they are also suitable in AC line filters, converters and lighting for the purpose of providing high-frequency noise suppression and line filtering. Most importantly, the working principle behind ECW-H16273JVB capacitors is based on their unique construction and precision winding process, which leads to the capacitor\'s outstanding performance in electrical charges storing and supplying.
