Aluminum electrolytic capacitors are an electronic component class used extensively in all fields of electrical engineering. The EDK107M004S9DAA capacitor is a miniature aluminum electrolytic capacitor with a case size of 18.5 mm x 25 mm and a height of 10.2 mm. It is a through-hole type unit with an operating temperature range of -60°C to +105°C. This makes it suitable for use in extreme temperature applications and for applications requiring higher capacitance values than ceramic capacitors.The EDK107M004S9DAA is a polarized capacitor with a rated voltage of 25 volts and a capacitance of 4,700 microfarads. The capacitor is constructed using a rolled-anode technology and is housed in a non-conductive resin case. This allows the component to operate in extreme temperature and moisture conditions while still maintaining a high level of reliability. Furthermore, the component has also been treated with corrosion-resistant materials, making it suitable for use in corrosive environments.The EDK107M004S9DAA can be found in a wide range of applications such as power supplies, servo motors, and computer systems. It is often used as a high-value, low-priced bypass, decoupling, or filter capacitor due to its large capacitance. Additionally, it is also suitable for use in signal processing applications, as it can help to reduce noise in certain circuits.The working principle of the EDK107M004S9DAA capacitor is based on the electrochemical process occurring between two electrodes. One electrode is composed of aluminum foil and etched spirally. The other electrode is composed of a porous paper that is soaked with electrolyte containing dissolved dissolved aluminum oxide and is connected to the positive lead of the capacitor. The aluminum oxide layer acts as an insulator, and when a voltage is applied, current flows through the electrodes to create a resistive electrochemical reaction. This reaction produces electrical charge carriers in the form of ions which build up in the form of electrical double layer at the surface of the electrodes. This creates an electric field within the dielectric that stores the electrical energy, resulting in a capacitance.Additionally, due to its design, the EDK107M004S9DAA capacitor is able to maintain its capacitance values throughout its operating temperature range. This makes it an ideal choice for applications which require high-level stability of capacitance and where failure could cause serious consequences.
