Aluminum electrolytic capacitors are widely used in a variety of electronic circuits requiring large capacitance values. One such series of these is the B43540A9687M007, offered by Panasonic. This aluminum electrolytic capacitor offers low impedance, long life, and excellent capacitance stability that can be applied in a wide range of applications.

The B43540A9687M007 is a tantalum electrolytic capacitor with a capacitance value of 4.7 µF. It has a maximum operating voltage of 20V, a rated temperature of -40 to +105°C with low impedance ratings. The capacitance is standard and maintained within a range of -10% to +10%. The size for the series is a small, dimensionally compact 6.3mm X 7.7mm and is offered in a radial leaded can package form.

This series of capacitor offers a wide range of applications in various motor control systems, such as DC brushless motors, servo systems and various power supplies. The capacitors can also be used in audio amplifier systems, home theaters, video cameras and other types of electronic equipment such as televisions, LCDs and plasma displays. This capacitor is also commonly used in automotive circuits such as headlights, dash illumination etc. It is important to note that the capacitor should not be used at temperatures exceeding 105°C.

The working principle of the B43540A9687M007 series capacitor involves the movement of electric charge and electrons between two separator plates that are positioned inside a non-conductive film. The separator plates are separated by an ionized solution that allows electric charge to flow between the plates. One plate is known as the anode and the other is the cathode. The aluminum electrolyte acts as an accumulating medium for the electric charge.

An outer can is positioned around the separator plates and the can helps the capacitor to maintain an ideal amount of voltage. The negative and positive terminals are also connected to the anode and cathode plate respectively. When current is applied to the two terminals, current will flow between the plates and a voltage difference will be created, allowing the capacitor to store the electrical energy. When current is removed, the stored electrical energy is released, discharging the capacitor.

The capacitance of the B43540A9687M007 series capacitor is measured in microfarads and can range from 2.2-10µF. It is important to follow the stated specifications, as using the capacitor beyond the specified parameters can cause damage and deterioration over time.

In conclusion, the B43540A9687M007 is a series of tantalum electrolytic capacitor highly suitable for a wide range of applications. The series offers excellent capacitance stability, low impedance, and long life. Its dimensionally compact size and standard capacitance make it well suited for motor control systems, home theatres, audio amplifiers, automobiles and many other types of electronic equipment.
