Aluminum – Polymer Capacitors: 20SEP68M+T Application Field and Working Principle

Aluminum-polymer capacitors, or “Al-Polymers”, are members of the capacitor family known as “super capacitors”. They combine the features of capacitors, such as long cycle life and high power handling ability, with those of batteries, such as large storage capacity and long discharge time. Due to these advantages, Al-Polymer capacitors have proven to be highly effective in a wide variety of applications and are often used in conjunction with conventional capacitors. The 20SEP1 98M+T capacitor is one example of an Al-Polymer supercapacitor.

20SEP68M+T Application Areas

The 20SEP68M+T is an aluminum-polymer electrolytic capacitor designed by Panasonic and Panasonic’s sister company Matsushita. It is designed to provide reliable energy storage and delivery in a variety of industrial and consumer applications. Its high-temperature tolerance and large-sized terminals make it well suited for use in applications such as industrial motors, sensors, and electro-mechanical devices. The 20SEP68M+T is also used in applications that require high power and high performance such as gaming consoles, robots, and automotive HVAC systems.

Working Principle of 20SEP68M+T Aluminum-Polymer Capacitors

Aluminum-polymer capacitors, including the 20SEP68M+T, are divided into two distinct types: the dry type and the wet type. The dry type consist of a “sandwich” of two aluminum electrodes separated by a layer of solid electrolyte. This type is capable of storing large amounts of charge and has excellent operating temperatures.The wet type is composed of two layers of solid electrolyte and an outer aluminum casing. This type is designed to provide higher capacitance, higher voltage operation, and higher temperature tolerance than the dry type. The 20SEP68M+T capacitor is a wet type.Al-Polymer capacitors, including the 20SEP68M+T, generally operate using a principle called “charge carriers”. Charge carriers are ions that are created by the capacitor\'s aluminum electrodes. The aluminum layers create a static electric field, causing the charge carriers to move to the opposite layer, where they are trapped and accumulate to form an electric field. This electric field allows the capacitor to store an electric charge, which is released when a current is applied. Due to their small size, Al-Polymer capacitors are able to store large amounts of charge and can discharge it quickly, making them well suited for applications that require high power and performance.

Conclusion

Aluminum-Polymer capacitors, like the 20SEP68M+T, are highly effective and versatile components capable of providing high power and large storage capacity in a wide range of applications. Their high temperature tolerance and large-sized terminals make them well suited for use in industrial and consumer applications. In addition to their capabilities, Al-Polymer capacitors enjoy a longer cycle life and higher power handling ability than conventional capacitors, making them a popular choice for many types of applications.
