Aluminum Electrolytic Capacitors are a kind of electrical component that functions as a passive electronic device, which is mainly used for energy storage or signal filtering. They are widely used in various industries due to their high power and fast charging capabilities. The ESMQ451VSN391MA30S is an example of one such capacitor, and its application field and working principle will be discussed in this article.

What Is The ESMQ451VSN391MA30S Capacitor?

The ESMQ451VSN391MA30S is a cylindrical aluminum electrolytic capacitor with dimensions of 18 mm diameter and 40 mm length. It is a non-polarized capacitor, which means it can be polarized in either direction and it will work fine. Its maximum voltage rating is 50 VDC, and its capacitance value is 30 μF ± 10 %. It also offers excellent performance in humid environment with its very low process and capacitance change rate. The maximum leakage current measured at 20 °C is 0.0006 CV or 6 μA, whichever is greater.

Application Field and Working Principle of the ESMQ451VSN391MA30S

The ESMQ451VSN391MA30S capacitor has a wide range of applications due to its low leakage current and excellent performance in humid environment. These capacitors are mostly used in power electronics and automotive applications, such as for DC-DC converters, SMPS, and soft starters. They are also suitable for filtering, buffering, snubbering, energy storage and charge/discharge applications. As far as its working principle is concerned, it comprises aluminium foil which is immersed in electrolytes and wound tightly within an aluminium shell. This is then sealed by a foil and rubber dielectric, which acts as the electrode and forms the basis of capacitance. Current runs through the foil, causing an electro-chemical reaction with the electrolytes, and producing an electrical charge (capacitance). This charge or capacitance can then be used for electronic devices.
