Aluminum - Polymer Capacitors

Aluminum - Polymer capacitors (also referred to as polymer electrolytic capacitors) are a modern technology based upon the same principles as traditional electrolytic capacitors. The main difference between the two types of capacitors is the dielectric material. Instead of using a porous oxide dielectric as in traditional electrolytic capacitors, aluminum-polymer capacitors use a polymer dielectric material.

The 2SXB150M is a type of aluminum-polymer capacitor, specifically a special case known as a Pseudo-Capacitor (PC). PC\'s differ from standard electrolytic capacitors in that they do not use electrolytes, but instead use a polymerized film as the dielectric, resulting in a very small leakage current. The 2SXB150M is an axial type component, through-hole, with a rated capacitance of 100uF at 6.3V. It features high capacitance and low Equivalent Series Resistance (ESR).

The 2SXB150M aluminum-polymer capacitors primary application is for decoupling and filtering of high-frequency power supplies, where very low ESR is required. This capacitor is also ideal for computer memory decoupling, ensuring stable operation and reducing noise from the power levels. It can also be used in audio amplifiers to correct frequency response and ensure clear sound reproduction. Additionally, it is suitable for use in switching power supplies, and can help reduce transient noise when used as an input capacitor in AC/DC transformers.

Working Principle

An aluminum-polymer capacitor’s working principle is almost identical to that of a standard electrolytic capacitor. Like with electrolytic capacitors, when a voltage is applied to the aluminum-polymer capacitor, the negative charge repels the positive ion of the electrolyte material surrounding the anode, creating a layer of ions around the anode. This layer of ions constitutes the “dielectric” and provides the same storage effect as found in a normal electrolytic capacitor.

The main difference between aluminum-polymer and standard electrolytic is the dielectric material. In standard electrolytic capacitors, the anode is surrounded by a thin oxide layer, while in an aluminum-polymer capacitor the anode is surrounded by a polymer dielectric material. This dielectric material is much more reliable, due to its inherent self-healing attributes, which is the ability of the dielectric material to self-repair any damaged areas, which restores it to its original condition.

The major advantage of this capacitor is the extremely low Equivalent Series Resistance (ESR), particularly at high frequencies. It ensures that the current passing through the capacitor does not cause any significant voltage drops, and ultimately provides improved power performance. The low ESR also has the added benefit of allowing for larger ripple currents, meaning that more current can be used with minimum power distortion.

This capacitor also features a long life expectancy, which means that the capacitor will last longer than traditional electrolytic capacitors. This is because the polymer dielectric consists of a solid sheet material, so it will not corrode or suffer any structural damage over time. Additionally, the dielectric exhibits excellent stability when exposed to temperature changes, ensuring reliability and consistent performance.

Overall, the 2SXB150M aluminum-polymer capacitor is an excellent choice for a variety of applications, such as decoupling and filtering of high-frequency power supplies, computer memory decoupling, and audio amplifiers. Its low ESR, long life expectancy, and excellent temperature stability makes it an ideal capacitor for these applications.
