Aluminum electrolytic capacitors (also known as aluminum electrolytic capacitors) are polarized capacitors whose anode electrode is made of a pure aluminum plate, which has a large surface area for forming an oxide, and is electrolytically formed on the surface of the aluminum plate. The oxide layer acts as a dielectric layer, and the second electrode is a liquid or solid electrolyte.

The B41694A5477Q9 is a type of aluminum electrolytic capacitor. This type of capacitor is a polarized capacitor, meaning that it is built with a positive and negative cathode. The positive cathode is an aluminum foil that has been anodized, and the negative cathode is a liquid electrolyte.

The B41694A5477Q9 capacitor has the following characteristics: it features a maximum working voltage of 50 volts, a maximum working temperature of 125°C, and an insulation resistance of 1000 mΩ. It operates over a range of operating voltages from 2.2 to 46 VDC and has a capacitance range of 0.22uF to 1000uF.

The most important feature of the B41694A5477Q9 is its extremely tight voltage tolerance, achieving a rate of 0.2%. This capacitor also has a maximum ripple current of 0.6 mA, making it suitable for applications where ripple current must be minimized.

The main application areas for the B41694A5477Q9 aluminum electrolytic capacitors include power supply filter circuits, soft start circuits, electromagnetic interference (EMI) filters, switching power supplies, SMPS, and voltage regulators. It is also commonly used to help reduce electrical noise in audio and video circuits.

In terms of its working principle, the B41694A5477Q9 aluminum electrolytic capacitor works on the principles of electrostatic charge. In this type of capacitor, one electrode contains an oxide layer, which acts as the dielectric layer. When a voltage is applied across the electrodes, a current flows through the oxide layer, building up charges on either side of the dielectric layer. This results in the build-up of energy, known as capacitance, due to the energy stored in the electric field.

The B41694A5477Q9 aluminum electrolytic capacitor is an ideal choice for applications where a high capacitance value is needed in a small package size, as well as for applications where tight voltage tolerance and ripple current are necessary. This type of capacitor is widely used in various electronic products, such as power supplies, home appliances, telecommunication equipment, and medical products.
