Aluminium-polymer capacitors or 63SXE33M capacitors are types of capacitors composed of polymer, typically polyethylene-terephthalate (PET), as the dielectric layer in a solid form. The electrodes are made of aluminium foil etched on one side and mostly aluminised PET film on the other side. Electrolytes are either an aqueous solution, a solid polymer or can be suspended in a gel.

Aluminium-polymer capacitors offer a good combination of capacitance, voltage ratings and high temperature endurance and are alternatively named Alu-Polymer Capacitors, 63SXE33M Capacitors or Polymer Aluminum Capacitors. This type of capacitor has emerged in recent years as a unique and dependable component in modern electronics due to its high capacitance, low ESR and small size.

63SXE33M capacitors have a wide variety of applications due to their combination of high capacitance, high voltage rating, temperature stability and very low ESR. These characteristics make them suitable for high-frequency applications, including power factor correction, transient suppression, decoupling and filtering.

The working principle of an Alu-Polymer Capacitor is the same as for other types of capacitors. It stores an electrical charge through the combination of an electrolyte and two metal plates separated by a dielectric material, resulting in the creation of two capacitors connected in parallel. The voltage at each plate is the same, while the current is different. This is because the capacitance of the two plates is different, as a result of their area, distance between plates and dielectric constant.

The main benefit of 63SXE33M capacitors is their low equivalent series resistance (ESR), offering a possible alternative to other technology such as multilayer ceramic capacitors (MLCCs), in some applications. This low ESR improves the efficiency of the capacitor and its ability to handle larger currents. Alu-polymer capacitors are also not as susceptive to board level stresses such as soldering heat and vibration.

In addition, these capacitors typically have a much longer useful-life than electrolytic capacitors due to their use of solid constructions. This makes them suitable for use in high vibration environments or when exposed to extreme temperatures. Alu-Polymer capacitors also have a very low self-discharge, meaning that the capacitor can remain at its rated voltage for extended periods of time.

An Alu-Polymer Capacitor offers a combination of features that are not available with other capacitor technologies. These features, combined with their small size, make them suitable for applications such as high-frequency switch-mode power supply (SMPS), communications systems, automotive electronics, and medical electronics.

63SXE33M capacitors are available in a variety of packages and sizes to fit almost any application. They are also widely available and offered by multiple manufacturers, ensuring that the market is highly competitive and prices remain low.
