930C4W3P3K Capacitors

Capacitors are electronic components used to store electric charge, with the aim of releasing this charge at a later time. Film capacitors are one type of capacitor which come in a variety of models, shapes, and sizes. Among these models, the 930C4W3P3K is one of the most popular of the film capacitors.

Film capacitors are easily identified by their cylindrical plastic or metal case. Film capacitors are sometimes referred to as “film dielectric capacitors” due to their enveloping case. Other names for the 930C4W3P3K type of film capacitor include “polyester film capacitor” and “Class B dielectric capacitor”. The basic components of film capacitors are metalized film and tin-plated steel plates. Inside the case, there is a number of single turns of the metalized film and tin-plated steel plates which take the form of a snubber or a screw.

Due to the presence of the special material for the capacitor, the 930C4W3P3K have a multi-stage or low inductance structure and a wide range of features like quick charge and discharge, low distortion, low ESR, high current discharge capability, and high reliability. It also has a temperature variation coefficient of over 5 - 6%. These features make the 930C4W3P3K a primary choice for applications involving audio, filter, recitification, timing circuits, and signal processing.

As film capacitors, the 930C4W3P3K employs an electrolytic solution to allow for the electrolytic film’s insulation layer. The tin-plated steel plates are dipped into this solution, with the formation of a conical void. The solution creates an inner electrode, which is connected to the external connection lead. This arrangement allows the capacitor to store electric charge at a given instant, and to release it when needed.

The 930C4W3P3K film capacitor boasts a working efficiency of almost 99%, which demonstrates the great performance of the capacitor. In addition, it has a medium-high insulation resistance, while its low dissipation factor helps reduce power loss and noise. The 930C4W3P3K film capacitor has a wide temperature range of -25ºC - 85ºC, making it suitable for a variety of applications.

In short, the 930C4W3P3K film capacitor is a popular choice for audio, filter, rectification, timing circuits, and signal processing, due to its high efficiency, insulation resistance, and temperature range. Its excellent performance is a testament to the claim that film capacitors are among the most reliable components in the electronics industry.
