Aluminum electrolytic capacitors are a kind of capacitors with a wide range of applications, and can be used in numerous areas such as power supply, power filter, half-wave rectification circuits, audio systems, frequency divider circuits, and so on. B43455C4478M7 is one of the kind, and is widely used in many electrical equipment owing to its excellent features.

B43455C4478M7 is a polarized capacitor made of aluminum foil and plastic film. It is non-inductive and polar, with the possibility of more than 85% of the rated voltage being applied, and a temperature compensation range from -40°C to 85°C. When in use, it should be positioned properly to ensure normal operation. It\'s also capable of standing vibration and shock.

B43455C4478M7 is an electrolytic capacitor with a wide variety of applications. Due to its low equivalent series resistance (ESR), high ripple current capability, long life, low impedance and low leakage current, it is perfectly suited for use in power supplies, switch-mode power supplies, computer systems, power tools, drives, communication equipment, audio systems, and many other home entertainment and industrial applications.

The working principle of B43455C4478M7 is a relatively simple one. When a positive voltage is applied to the anode, a thin oxide layer on the aluminum surface will be polarized, which will then create a micro-oil film of insulating material. The charged aluminum foil acts as the "plate" of the capacitor, and the area between the two aluminum foils becomes the “dielectric”, which stores electrical energy. The electric energy stored is determined by the capacitance and voltage applied to the capacitor.

The construction of the B43455C4478M7 capacitor starts with the anode and cathodes manufactured from highly pure aluminum. Each aluminium foil is then rolled and electrolytically etched to form a molten sense connecting with the liquid electrolyte. Then they are wax-treated, rolled, and immersed in an organic solvent. Finally, the electrolytic foil is sandwiched and laminated together with the plastic film. This unique construction renders the capacitor capable of withstanding extreme temperature and harsh environmental conditions.

In summary, the B43455C4478M7 aluminum electrolytic capacitor is a versatile component with many desirable abilities, such as low impedance, high capacitance, and high ripple current rating. Its low level of leakage current ensures its safety and reliability in areas such as power supplies, systems, and audio equipment. As such, it has become one of the most widely used capacitors in the market.
