Aluminum electrolytic capacitors are widely used in circuit design and are one of the most cost-effective components that provide energy storage. One of the more popular components of this type of capacitor is the B43504A9687M62, a radial leaded end-sealed version that is typically mounted on the circuit board.

The B43504A9687M62 is most often used in power supplies, DC-DC converters, and DC-AC inverters where its high energy density, low cost, and compact package size make it a suitable choice. Additionally, this capacitor is widely used in motor drive circuits, such as those found in automotive applications, as well as in various consumer and industrial applications.

In terms of its technical characteristics, the B43504A9687M62 offers a wide operating temperature range, from -40°C to +105°C. The rated voltage range for this capacitor is anywhere from 4 to 16V, with a maximum working voltage of 16V. The capacitance range of this aluminum electrolytic capacitor is 35 to 470 μF, offering a wide range of values for designers to choose from. Lastly, the package size of the B43504A9687M62 is surprisingly small, with a diameter of 10mm and a length of 20mm.

The working principle behind the B43504A9687M62 aluminum electrolytic capacitor is one that utilizes a chemical reaction between an electrolyte and an oxide layer formed upon a metal foil. On the inside of the capacitor, there are two layers of aluminum foil, one acting as a ‘positive’ electrode and the other as a ‘negative’ electrode. The electrolyte used is typically a liquid or a gel, and between these aluminum foils is the dielectric, which is an oxide layer of aluminum.

When voltage is applied across the two foils, current flows and the electrolyte erodes the oxide layer on the aluminum foil. This creates a porous layer that increases the amount of electrical charge that the capacitor is able to store. This also increases the capacitance of the capacitor, allowing it to store more energy. The amount of capacitance of the B43504A9687M62 is dependent on its voltage and its size.

The capacitor also has a varistor material that helps protect against voltage surges. This material is connected in parallel with the capacitor and acts to absorb any incoming transient voltages, thereby preventing damage to the capacitor or any other components that are connected to it. This is a very useful ability to have in situations where the capacitor is likely to be exposed to such high voltages, providing a greater level of protection to both components.

In conclusion, the B43504A9687M62 aluminum electrolytic capacitor is an ideal choice for applications where cost and size are important factors. Its wide operating temperature and voltage range, as well as its wide capacitance, make it suitable for use in a variety of different applications. Its working principle, which utilizes a chemical reaction between an electrolyte and an oxide layer to increase its capacitance, helps ensure that it is able to store energy efficiently and properly. Lastly, the inclusion of a varistor material helps protect its components from any potentially damaging transient voltages.
