Aluminum Electrolytic Capacitors (AECs) are devices that store energy in an electrostatic field. They are composed of two aluminum plates separated by an electrolyte. The plates are typically a square or rectangular shape and may be made from anodized aluminum or foil. They are often used in power supply circuitry, filters, amplifiers, snubbers, and charge pumps. The MAL203029338E3 is an AEC designed to provide high capacitance and ripple current over an extended temperature range. This capacitor is rated for 10,000 hours at 85°C with no voltage derating.

An AEC works by storing energy in an electrostatic field created between two metal plates. The metal plates act as one conductor (anode) and the electrolyte as the other (cathode). When a voltage is applied, the electrolyte temporarily becomes an insulator, allowing charge to accumulate on the metal plates. The capacitance is determined by the area of each plate and the distance between them. The metal plates are typically anodized aluminum, providing additional surface area for the electrostatic field.

The MAL203029338E3 is an Aluminum Electrolytic Capacitor with a capacitance of 330 μF and a rated working voltage of 25 VDC. It has an extended temperature range of -55°C to +85°C and is rated for 10,000 hours at 85°C with no derating. It also features a high ripple current rating of 1.55A. This capacitor is designed for general purpose applications and can be used in filter, snubber, and charge pump circuits.

The working principle of an Aluminum Electrolytic Capacitor can be summarized as follows. When a voltage is applied to the capacitor, the electrolyte between the metal plates temporarily becomes an insulator and charge accumulates on the plates. This creates an electrostatic field between the plates which stores energy. The level of capacitance, or the amount of energy that can be stored, depends on the size of the plates and the distance between them.

The MAL203029338E3 is an Aluminum Electrolytic Capacitor designed to provide high capacitance and ripple current over an extended temperature range. It can be used in general purpose applications such as power supply circuitry, filters, amplifiers, snubbers, and charge pumps. Its extended temperature range of -55°C to +85°C and its 10,000-hour life at 85°C make this capacitor a reliable and durable choice for a wide range of applications.
