B43601A2397M87

Aluminum electrolytic capacitors are widely used in numerous applications in areas such as consumer electronics, industrial equipment, automotive applications, and military and aerospace systems. Their use allows for dense and miniature circuit designs, fast charging and high voltage capability, and long operating life. An aluminum electrolytic capacitor, coded B43601A2397M87, is a polarized capacitor with an anode of aluminum and a cathode of electrochemically formed and deposited aluminum oxide.

Application Field

B43601A2397M87 aluminum electrolytic capacitors are typically used for high frequency and power filtering in switching power supplies, as specialty capacitors in RF networks, and in general audio and video circuitry. The B43601A2397M87 are polarised electrolytic capacitors that exhibit a much higher capacitance-to-mass ratio than competing types of capacitors. This makes them particularly suitable for electronic circuitry, where the dimensions need to be kept to a minimum.

Working Principle

The B43601A2397M87 aluminum electrolytic capacitors operate on the principle of a dielectric layer formed on the anode by an electrolytic action in an electrolyte. The dielectric oxide layer provides insulation between the anode and cathode, enabling current flow through the capacitor when a voltage is applied.When a voltage is applied to the B43601A2397M87 electrolytic capacitors, an electric field is generated between the anode and the cathode, setting up a motion of electrons, and the electrolyte is electrochemically broken down, forming an insulating layer of dielectric. This dielectric layer is composed of two layers, a thin one composed of aluminum oxide, and a thicker one made up of various organic liquids. The aluminum oxide layer has a low capacitance but a very high insulation resistance. The organic layer has a higher capacitance but is very susceptible to degradation in electrolyte.

The B43601A2397M87 aluminum electrolytic capacitors have a C/V value between 5-20µF/V. This is higher than most competitive technologies, allowing for high filtering and faster charging. The capacitors also possess a long operating life due to the fact that they are less affected by temperature and humidity variations, which would reduce the life expectancy of other types of capacitors.

In summary, the B43601A2397M87 aluminum electrolytic capacitors are small, compact, and have a high capacitance-to-mass ratio, making them ideal for many applications in industries such as consumer electronics, industrial equipment, automotive applications, and military/aerospace systems. They provide high filtering and faster charging capabilities, and a long operating life.
