Aluminum electrolytic capacitors are a type of polarised capacitor that operate with an electrolytic acting as an anode, and characterized by high capacitance values in a small package. They are available in a variety of shapes and sizes with a wide range of ratings. The B43504F2687M80 is a conductive polymer based aluminum electrolytic capacitor designed with a large capacity and high reliability.

The B43504F2687M80 is designed for use in applications such as voltage regulator and dc-dc converter modules, ac-dc converter modules, AC line filters, and subsystems for servers, switches, and routers. This capacitor is also suitable for other applications where large output current ripple is encountered.

The B43504F2687M80 features a wide temperature range (-55℃～105℃), long life span (3000h at +105℃), ESR 40mΩ (Mean 20kHz @ 25℃), and a rated voltage of 8V. This capacitor has a capacitance of 33μF and a maximum operating frequency of 100kHz.

The structure of the B43504F2687M80 is made of a conductive polymer aluminum electrolytic cap with a aluminium case and a tinned-copper terminals. Inside the capacitor, the electrolyte is a mixture of an aluminium oxide film (-) and an aluminium foil (+). In the anode layer, a small hole is left in the aluminium oxide film to serve as the gate. The cathode layer is made up of a thin layer of tin plated copper which serves as the dielectric surface. When a voltage is applied, a current flows between the anode and the cathode, with the anode being the positive and the cathode being the negative. This current creates an electric field that causes the electrons to flow, thus producing capacitance.

The B43504F2687M80 also has a few other features including a relatively low ESR compared to other equivalent capacitors, making it ideal for applications requiring higher frequencies and large ripple current. It has high heat resistance, making it suitable for use in high temperature environments. Additionally, its robust structure prevents it from breaking or suffering fire even in abnormal operating conditions.

In conclusion, the B43504F2687M80 aluminum electrolytic capacitor is a high quality, highly reliable capacitor designed for use in high power applications such as voltage regulator and dc-dc converter modules, ac-dc converter modules, AC line filters, and subsystems for servers, switches, and routers. It has a wide temperature range, long life span, low ESR, and good heat resistance, making it a great choice for these types of applications.
