Aluminum electrolytic capacitors are a vital part of electronic systems, being used in everything from amplifiers to power supplies. The ALS70H393DB025 is an electrolytic capacitor from the ALS series from Panasonic. This capacitor can be used in a wide range of applications and has a unique working principle.

Overview

The ALS70H393DB025 is a capacitor with a nominal capacitance rating of 0.33F (330uF) and a working voltage of 25V. It has a short temperature range of -40°C to +105°C. The package type of this capacitor is radial lead, which means it has one short lead and one long lead, making it easier to connect to other parts in an electronic system. The size of its case is 7mm in diameter by 9.3mm in height, and the total weight of the capacitor is 0.8g. The insulation type is a low-resistance dendritic film, meaning the capacitor has an excellent dielectric strength.

Application Field

The ALS70H393DB025 has a variety of uses in electronic circuits. It is often used as a filter capacitor in power supplies, audio applications, and automotive electronics. It is also used as an input and output capacitor in amplifier circuits. It can also be used to store energy in electronic circuits, acting as a sort of battery. This capacitor is also well suited for DC-DC converters, as it is able to maintain a high capacitance over its useful temperature range.

Working Principle

Aluminum electrolytic capacitors are made up of two conductive electrodes, called the anode and the cathode, which are separated by a dielectric (the electrolyte). As current passes through this capacitor, electrons accumulate on the surface of the anode, forming an electric field between the two plates. This electric field is what stores the energy in the capacitor and also isolates the two plates from each other. The capacitance of the capacitor is determined by the size and shape of the plates and the thickness of the dielectric.

The ALS70H393DB025 is a type of aluminum electrolytic capacitor, which means that it uses a combination of aluminum and an electrolyte to form the capacitor. The anode of this capacitor is made up of aluminum, and the electrolyte is composed of a mixture of ethylene and propylene carbonates. This combination allows the capacitor to have a low ESR (Equivalent Series Resistance), which gives it a high capacitance and enables it to efficiently store and release energy.

Conclusion

The ALS70H393DB025 is a type of aluminum electrolytic capacitor that is commonly used in a variety of electronic circuits. It has a capacitance of 0.33F and a working voltage of 25V, and it has a wide temperature range of -40°C to +105°C. This capacitor is well suited for use in filter circuits, power supplies, amplifier circuits, and DC-DC converters. Its working principle is based on two conductive electrodes, the anode and the cathode, separated by a dielectric. The capacitance of the capacitor is determined by the size and shape of its plates and the thickness of its dielectric.
