Aluminum - Polymer Capacitors

Aluminum - polymer capacitors, also known as electric double-layer capacitors (EDLCs), are a relatively new type of capacitor used in various applications. They are constructed from two thin film layers of metalized conductive polymer sandwiched between aluminum foil strips electrodes. This construction provides a higher energy density, much higher volumetric power density and more cyclic performance than traditional aluminum electrolytic capacitors.

The 10SWZ47MR25 is an aluminum-polymer capacitor manufactured by Panasonic which is designed for use in a wide range of applications including automated lighting control, ultrasound imaging, radiological equipment, electric motor control, and battery backup systems. It is a single-sided polarized capacitor with a capacitance of 47µF and rated voltage of 25V.

Working Principle

The working principle behind aluminum-polymer capacitors is similar to that of electrolytic capacitors. They use an anode and a cathode, which are usually made from metallic and conductive polymer layers respectively. When a voltage is applied across the capacitor, the opposite charges accumulate and the electric double layer is formed, thus providing the required capacitance value. The maximum operating voltage is determined by the thickness of the insulating layer and the breakdown voltage.

The 10SWZ47MR25 aluminum-polymer capacitor works by storing energy in the electric double-layer created by the anode and cathode layers. When a voltage is applied to the device, electrons move from the anode to the cathode while ions move in the opposite direction. This creates a stored charge in the double-layer and provides the device with its required capacitance value.

Applications

The 10SWZ47MR25 aluminum-polymer capacitor is suitable for a variety of different applications. It can be used for automated lighting control, ultrasound imaging, radiological equipment, electric motor control, and battery backup systems. Its low-profile construction also makes it suitable for high-density, miniature electronic modules and small medical devices.

Due to its high-energy density and low-profile construction, the 10SWZ47MR25 aluminum-polymer capacitor is also suitable for use in applications where high performance, low-profile components are required such as receivers, ultra-wideband radar systems, and automotive safety systems. Its long shelf-life and high operating temperature range also makes it suitable for a wide range of other applications.
