Aluminum - Polymer Capacitors

With the rapid increase in the demand for energy storage capabilities and the need for smaller, lighter capacitors, aluminum-polymer capacitors have been developed to address these needs. The first aluminum-polymer capacitors (A-P caps) were introduced in the 1950s, made from a combination of an aluminum foil and an ionic polymer of sulfonic acid. This combination creates very reliable capacitors that are still in use today. They have since been further developed and improved, with many different types and configurations.

The A-P caps are comprised of aluminum electrodes with a layer of ionic polymer sandwiched between them. The polymer is typically a sulfonated or halogenated hydrocarbon, which serves as both an insulation layer and a leak-blocker. This design makes the capacitors highly resistant to overcharging and/or overdischarging. Furthermore, as the majority of the electricity is retained in the polymer layer, compared to a traditional wet electrolyte capacitor, A-P caps can provide much higher energy storage in a much smaller package.

APS-2R5ELL681MHB5S is a type of A-P caps that is an excellent solution for applications that require a very small, lightweight, and reliable capacitor. It is a low-profile, surface-mounted type aluminum-polymer capacitor with a solid-state sulfur hexafluoride (SF6) insulation system, with a rated capacitance of 200 VDC, able to store 1F of electrical energy. The SF6-filled housing provides additional protection against electrostatic discharge. As a result, this type of capacitor can be used in a wide range of applications, including but not limited to, power-supply applications, resonator filters, switching power supplies, and voltage sensing.

The working principle of the APS-2R5ELL681MHB5S capacitor is, in short, to use the electrodes of the capacitor (the aluminum and the polymer layers) as a pair of plates that are separated and insulated by the SF6-filled housing. When voltage is applied to the APS-2R5ELL681MHB5S, charge builds up on the plates, creating an electric field between them. This field allows for the stored electrical energy to be released for use in the application.

The APS-2R5ELL681MHB5S is a very efficient, reliable and cost-effective capacitor, with excellent performance even in the most demanding applications. It is extremely light and can fit into even the smallest spaces, making it a great choice for all types of applications. Additionally, it offers excellent mechanical strength and is resistant to environmental extremes such as temperature and humidity.

In conclusion, the APS-2R5ELL681MHB5S aluminum-polymer capacitor is an extremely effective and reliable solution for applications such as power-supply, voltage sensing, and resonator filters, that require a small form factor and reliable storing of electrical energy. It is a cost-effective, durable and light weight solution and has become increasingly popular due to its various advantages.
