Aluminum Electrolytic Capacitors have become one of the most popular types of capacitors in modern electrical and electronic applications. They are also known as wet electrolytic capacitors or electrolytic capacitors with polarizing media. They can be found in a variety of size, type, and application fields.

The B41890B6477M is an aluminum electrolytic capacitor used in a wide range of application fields such as cell phones, multimedia electronics, telecommunication systems, automotive application, computer networks, home appliances, and industrial control applications. This device works with a working voltage of 2.5 V and a working temperature range of -55 to +125°C. It features a capacitance of 1.1µF, a maximum ripple current of 10A, a casing size of 8mm x 11mm, and a pin pitch of 5.0mm.

The working principle of an aluminum electrolytic capacitor is similar to those of any other capacitors. The device consists of two electrode plates, separated by a dielectric. The difference lies in the dielectric, which is made of an electrolyte solution called an electrolyte gel. One electrode is made up of a layer of aluminum oxide while the other is made of pure aluminum. This creates a large area of contact between the plates, allowing it to store a greater level of charge than most other capacitors.

The aluminum oxide layer acts as the dielectric, which is responsible for controlling the amount of charge stored in the capacitor. When voltage is applied to the capacitor, the electrons move between the plates, resulting in a flow of current through the capacitor. This causes the stored charge to increase and eventually reach a peak, after which the device starts to discharge. This makes aluminum electrolytic capacitors particularly useful for storing and releasing power at specific times.

In addition to its electrical characteristics, the B41890B6477M aluminum electrolytic capacitor also has some important mechanical features. It is designed with a 10mm height, an installed height of 8mm, and a rated lifespan of 2000 hours. It also has a solderability of 300 cycles and terminal strength of 115 cN, making it appropriate for reliable and robust connections. Additionally, its metal-oxide film is rated at +125°C to ensure reliable performance even in extreme temperatures.
