Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized capacitors which have an anode made of aluminum and a cathode made of an oxidized aluminum layer. They are one of the most commonly used capacitors in modern electronics, due to their cost, relatively large capacitance, and range of ratings.

678D108M010DM4D Application Field and Working Principle

The 678D108M010DM4D capacitor is a long life, low ESR aluminum electrolytic capacitor with a rated working voltage of 10 VDC. It is most commonly used in high frequency electronic equipment such as switching power supplies, AC/DC adapters, uninterruptible power supplies, and UPS systems, as well as computer systems, telecommunications systems, and industrial automation equipment.

The 678D108M010DM4D capacitor has a non-solid electrolyte and a four-pin design. It has an operating temperature range of -40 °C to +85 °C, and offers a high ripple current rating of 104 mA. It is designed for high temperature and high frequency applications, and has a frequency range of 0 - 200 kHz. It is also designed to withstand high vibration and shock.

The working principle of an aluminum electrolytic capacitor is based on the Faraday Law of Capacitance, which states that the charge needed to form a capacitance is directly related to the area of the electrodes. The aluminum electrolytic capacitor has a large spacer between its electrodes, which makes it capable of holding a large charge. When the capacitor is connected to electrical current, the aluminium acts like an ion sponge, allowing charged ions to transfer between the electrodes.

The ions move from the anode to the cathode, where they are attracted by the metals of higher surface area. This causes the charge to build up, creating an electrostatic field that creates a potential difference between the two electrodes. This potential difference enables the current to flow through the capacitor, creating an electrical circuit.

Aluminum electrolytic capacitors are highly efficient, and their unique construction gives them a wide range of uses, making them a popular choice for many electronic circuits. The 678D108M010DM4D capacitor is a reliable and stable choice for high frequency and high temperature applications.
