Aluminum - Polymer Capacitors

Aluminum-based polymer capacitors, also referred to as hybrid capacitors, are a type of electrochemical capacitor type, combining the high energy density of a liquid electrolyte with the volumetric efficiency of a solid electrolyte. As such, this type of capacitor is capable of delivering the necessary output for ultra-high voltage power electronics, in a size that can be comfortably accommodated in even the tightest of applications.

The EEH-HE0D271R is a hybrid capacitor made with a blend of aluminum and various polymers materials. It is especially designed for the high frequency, high power applications. It features a wide temperature range of -40 to +85 degrees Celsius and the high dielectric strength that makes it suitable for most applications.

This type of capacitor has a multiple layer construction which consists of two separate capacitors connected in series, each one containing a different electrolyte type. It has a higher capacity than an aluminum electrolytic capacitor, since it uses larger quantities of electrolytes and thus a greater amount of surface areas, providing a higher capacitance per unit mass than a single-layer capacitor. There is also an advantage in that the two capacitors share the same structural form, making installation simpler. This type of capacitor is often used in automotive engine and powertrain control modules, as well as in industrial automation systems such as motion controllers and programmable logic controllers.

The EEH-HE0D271R has a working principle not seen in other capacitors. It works by storing energy in the form of electrons on the surface of the capacitance material, and the electrons are discharged across the junction between the two layers of the capacitor. This ability to store and release electron charges rapidly allows for a high input voltage, but reduces the potential risk of damaging sensitive electronic circuits. Additionally, its long cycle life attributes to its stability and dependability for electrical systems.

In conclusion, the EEH-HE0D271R aluminum-polymer capacitor is ideal for applications that require a high capacitance and a low to medium ESR (equivalent series resistance). It provides power output at high frequencies and is suitable for a wide operating temperature range. This is the perfect choice for automotive, industrial and power supply applications due to its reliable performance and long cycle life.
