Aluminum electrolytic capacitors are capacitors with solid electrolytes and typically consist of two aluminum plates with an electrically conductive non-solid electrolyte as the separator. These capacitors are widely used for general power supply and signal coupling applications. They have an extremely high capacitance-to-volume ratio and are very inexpensive, making them ideal for many applications.

The MAL204217688E3 is a Radial Lead Aluminum Electrolytic Capacitor that is ideal for general purpose power supply and signal coupling applications. It features a long life and high volumetric efficiency. This type of capacitor is manufactured using a large-diameter anode foil, allowing it to store a relatively high capacitance in a small volume. Its aluminum-zirconium construction ensures excellent leakage performance and long life.The MAL204217688E3 has a capacitance range of 2200uF to 4000uF and a voltage range of 400V DC to 630V DC. It also has a low equivalent series resistance (ESR), making it suitable for both high-frequency and low-frequency use. The operating temperature range of this capacitor is -40°C to +105°C. The working principle of this capacitor is based on electrolytic double layer capacitance. At the positive electrode, cations move to the negative electrode, while anions or electrons move to the positive electrode. The space between the two electrodes is filled with an electrolyte and on this interface, a double layer forms and acts as the capacitance. This double layer formed on the electrode surfaces stores electric energy and acts as a capacitor. When using the MAL204217688E3, adequate ventilation should be provided to ensure good thermal performance. To ensure its longevity, the ambient temperature should be kept under specified temperatures, as the higher temperature reduces the life of the capacitor. In applications involving DC bias with high ripple current, such as that of TV power supplies or switched-mode power supplies, the capacitor needs to be derated so that the maximum voltage is not exceeded.The MAL204217688E3 is an ideal choice for applications requiring a capacitor with a high capacitance-to-volume ratio, good thermal performance, low equivalent series resistance and long life. It can be used in many general purpose power supply, signal coupling, automotive, military and telecommunication applications. Its aluminum-zirconium construction ensures excellent leakage performance and durability.
