Aluminum electrolytic capacitors are widely used electronic components, as they are often used to buffer and decouple high frequency disturbances and lower the levels of electromagnetic interference (EMI) with its associated resonant circuit. The 688LBB016M2BC is one of the class of aluminum electrolytic capacitors that are widely used for various applications. This article gives an overview of the application fields and working principles of the 688LBB016M2BC.

Application Fields

The 688LBB016M2BC is a radial leaded aluminum electrolytic capacitor with a capacitance of 0.15mF. This type of capacitor is often used in power electronics and consumer electronics, including uninterruptible power supplies, automotive electronics, digital audio and video electronics and a wide variety of consumer and professional appliances. This capacitor is also widely used in DC/DC and AC/DC converters, switching power converters, and electronic ballasts as well as in high frequency applications such as switching and AC/DC converters. In power electronics applications, the 688LBB016M2BC is often used for energy storage and line waveform shape control. In consumer electronics, the 688LBB016M2BC is used to filter electronic noise.

Working Principle

The 688LBB016M2BC is an aluminum electrolytic capacitor which is made up of an electrolytic anode, a cathode, and a dielectric. The electrolytic anode and cathode are composed of highly porous aluminum powders that contain a double layer of saturated ions. The dielectric is a thin layer of aluminum oxide. The electrolyte serves as a separator between the two metals, and it enables the dielectric layer to form a strong capacitance. When a voltage is applied to the capacitor, the current flows from the anode to the cathode through the electrolyte. The dielectric layer prevents the electrons from passing through it, thus storing charge. At this point, the capacitor has a capacitance, which is the ratio of the charge stored in the capacitor to the applied voltage. The capacitance of an aluminum electrolytic capacitor is determined by its size and its surface area.

The capacitance of the 688LBB016M2BC can be increased by increasing its surface area. This is done by designing the anode and the cathode with multiple concentric folds. This increases the surface area and thus increases the capacitance of the capacitor. The 688LBB016M2BC also has a large temperature coefficient, which means that the capacitance of the capacitor changes with the temperature. This means that the capacitor should not be used in applications that require high-temperature operation.

Conclusion

The 688LBB016M2BC is a radial leaded aluminum electrolytic capacitor that is commonly used in power electronics and consumer electronics applications. Its capacitance is determined by its size and surface area, and its temperature coefficient is large. This makes it suitable for applications that require low-temperature operation.
