Aluminum electrolytic capacitors are widely used in power supplies, electronic amplifiers, switching power supplies, and various electronic control circuits due to their relatively large capacitance and long life. The B41890A4158M aluminum electrolytic capacitor is a radial-type, low-profile, polar aluminum electrolytic capacitor type with a rated capacitance of 4.7µF. It is designed for operation within the range of -25°C to +85°C.

The B41890A4158M aluminum electrolytic capacitor utilizes a combination of an electrolytic anode and a manganese dioxide cathode. It consists of an anode formed by winding an aluminum foil into a cylindrical shape and coating it with a solid electrolyte. The cathode is a sintered manganese dioxide powder attached to the inside of the anode. The anode and cathode are separated by an ion-permeable membrane and are sealed in a plastic case.

The working principle of the B41890A4158M aluminum electrolytic capacitor lies in the formation of an electrical double layer at the anode/electrolyte interface in an electrolytic capacitor. When a potential is applied to the capacitor, an electric field is formed and charges accumulate on both interfaces. This creates an ingeniously designed electrical double layer that acts like a barrier to movement of charged particles so that only the current of capacitance can flow through the capacitor, thereby allowing the capacitor to store charge.

The B41890A4158M aluminum electrolytic capacitor has a wide range of applications wherever capacitors are used, such as in power supplies, electronic amplifiers, switching power supplies, and various electronic control circuits. Its small size and low profile make it ideal for use in limited space and where a low profile design is required. With its rated capacitance of 4.7µF, it can be used to filter noise, smooth out ripple, and store energy in circuits.

The B41890A4158M aluminum electrolytic capacitor is an excellent choice for applications requiring a low-profile, reliable capacitor. Its combination of small size and large capacitance makes it suitable for a wide range of applications, while its long life ensures a reliable service. Its low profile design also allows it to be installed in limited space where other larger capacitors may not fit.
