Aluminum-Polymer Capacitors (APCs) is a type of electrolytic capacitor which contains a layer of polymeric material between the anode and the cathode. The polymeric material has the capability to absorb and store electric energy. It is widely used in a variety of applications including automotive, aerospace, consumer electronics, medical and military applications.
EEF-SR0E181R4 is a type of Aluminum-Polymer Capacitor (APC). It is a radial leaded electrolytic capacitor that has a dielectric of polyethylene-terephthalate (PET) and a capacitance of 20µF (microfarads) to 1F (farad). It is also rated with a working voltage of 16V and an operating temperature of -40 to +85 °C.
The application field of EEF-SR0E181R4 is very wide, and the main application areas include the following:
- Automotive (such as ABS, air bags and other safety system related applications)
- Cellular phones, digital cameras and other consumer electronics
- Medical equipment and instruments
- Aerospace and military applications
- Industrial automation and control systems
The working principle of EEF-SR0E181R4 is based upon the capacitive effect of the polymeric layer. Whenever there is a potential difference between the two terminals of the capacitor, an electric field is produced, which in turn polarizes the polymeric layer sandwiched between them. This polarization results in a storage of electrical energy and a separation of charge. While this happens, the polymeric layer prevents any current to flow through it thus controlling the current flow and ensuring its uniformity. This process of charge storage and charge separation is known as capacitive effect.
Likewise, when the potential difference is reversed, the charge separation and charge storage is reversed as well, which releases the stored energy. Thus, an AC voltage can be used to repeatedly charge and discharge the capacitor in order to restore the polymeric layer to its original state.
EEF-SR0E181R4 is a very versatile and reliable device which finds a wide range of applications in automotive, aerospace, consumer electronics, medical and military fields due to its durability, excellent electrical characteristics and low cost. Its working principle is based on the capacitive effect of the polymeric layer, which makes it an ideal choice for various applications.
