Film Capacitors play a critical role in the modern world, and their implementation continues to be an integral part of certain applications, such as in signal filters, snubber circuits, micro-controllers, and more. This article will discuss the application field and working principle of model number 100ST473M3216, a popular film capacitor used in a wide array of industrial applications.

Film capacitors are a type of non-polar capacitor, composed of two electrodes sandwiching an aluminum oxide, polyester, or polypropylene dielectric material, which stores energy. These capacitors maintain a relatively low amount of losses due to their use of the dielectric material, and this makes them ideal for a variety of industrial applications.

Model number 100ST473M3216 is a 4.7μF rated capacitor designed for a 50V DC voltage rating stamped as 350V DC. It features a polyester dielectric film, with extra sealing for added protection against moisture and other environmental conditions. The capacitors operate in a temperature range from -25°C to +85°C.

This model number has a wide range of applications in the automotive, electrical switchgear, and industrial electronics industries. Its key feature is the electrical insulation, essential for many of these applications. It works as a snubber in electrical switchgear, which controls the switching action of inductive loads. Film capacitors are also used in DC circuits, since they are less prone to failure compared to other types of capacitors. In automotive applications, this model number finds uses for filter circuits, noise suppression, and voltage smoothing purposes.

In addition to the above, this model number is highly popular for AC/DC power circuit smoothing, industrial ups systems, power amplifiers, transmitters, uninterruptible power (UPS) systems, power supplies, communication systems, and various electronic devices.

In terms of its working principle, this model number employs the basic capacitor mechanism, in which the dielectric material is placed between the two metal plates (anode and cathode). This stores the electric charge at the interface, which can subsequently be released when needed. The metal plates, also known as electrodes, are able to hold onto the charge. In a DC circuit, the electrical current of the charge flows from the anode to the cathode, while in an AC circuit, the electrical charge flows in both directions.

These capacitors also feature a wide range of capacitance values, ranging from 0.472μF to 4.7μF, which makes them a perfect choice for applications ranging from in-line protection against Arc-Fault Currents in harsh industrial environments to the very sensitive circuitry in medical electronics. In industrial settings, these capacitors are used in power factor correction circuits to reduce harmonics and improve power quality.

In summary, the 100ST473M3216 is a Film Capacitor model, employed widely in many industrial and automotive applications. Its electrical insulation properties and resistance to failure make it an ideal choice for power-related electronics, particularly for use with DC and AC circuit smoothing and electrical switchgear. It has a working principle that employs the basic capacitor mechanisms, which involves the storage and release of electrical charge through two electrodes and a dielectric material.
