Aluminum Electrolytic Capacitors, also known as electrolytic capacitors or electrolytic capacitance devices, are the most commonly used type of capacitors. The B43305A9108M87 is a rated series, rated series means that the capacitors in the same series of capacitors all have the same specifications and features. The B43305A9108M87 is an axial long lead aluminum electrolytic capacitor.

The main function of the aluminum electrolytic capacitors is to store electric charge. The principle of aluminum electrolytic capacitors is that one lead is connected to the anode, and the other lead is connected to the cathode. The capacitance of the capacitor is determined by the area of the anode. When a voltage is applied across the capacitor, positive charges accumulate on the anode and negative charges accumulate on the cathode. The dielectric material between the electrodes is a layer of aluminum oxide. When a voltage is applied to the capacitor, the shell of aluminum oxide is formed, and electric charges accumulate on two electrodes, forming a capacitance.

The specifications for the B43305A9108M87 axial long lead aluminum electrolytic capacitor, specified as an 82/125 motor and an 80/105 starter, include a rated voltage of 4VDC, a capacitance of 10μF, a size of 7x11mm, a ripple current rating of 1A, and a leakage current rating of 1mA (at 25°C). The operating temperature of this capacitor is maximum 85°C, and the temperature coefficient is -120±60ppm/K. The series is also RoHS, REACH, and UL compliant.

The B43305A9108M87 aluminum electrolytic capacitor series are used in a variety of applications, such as automotive electronics, professional audio equipment, power supplies, frequency conversion and various commercial home appliances. In automobiles, these capacitors are used in the starter and motor. Specifically, the 82/125 motor capacitors and 80/105 starter capacitors are used. For professional audio equipment, aluminum electrolytic capacitors are used for audio/video power supply applications, which provide smoother voltage and higher audio quality.

In general, aluminum electrolytic capacitors can provide very high capacitance, low cost, and long life. Although the quality of some aluminum electrolytic capacitors can be significantly affected by their environment, by choosing a suitable series of capacitors, such as the B43305A9108M87, the desired performance of the product can be achieved.
