Aluminum Electrolytic CapacitorsAluminum electrolytic capacitors are a popular type of capacitor used in electronic circuits. They are made of two aluminum foils which are separated by a paper or film dielectric material. One of the foils is etched with a conductive layer and the other is covered by an electrolytic solution to create an electrostatic field. The dielectric medium is then rolled up into the compact shape of the capacitor.The most common type of aluminum electrolytic capacitor is the LNU2H122MSEG. It has a capacitance range of 0.047F to 2.2F, a rated voltage of 12VDC, and a maximum operating temperature of 85°C. It is a medium size axial leaded aluminum electrolytic capacitor with a radial orientation. The capacitor has an electrolytic solution-filled canister with a sliding seal and snap-fitted covers made from high-grade aluminum. The anode and cathode lead wires are braided for additional strength. The outer canister and internal components are hermetically sealed for additional protection against outside elements.The main application of the LNU2H122MSEG aluminum electrolytic capacitors is decoupling in audio and video circuits. Decoupling is the process of reducing voltage spikes or current in power supplying circuits. The capacitors capacitance acts like a reservoir and absorbs any sudden changes in the current or voltage. This helps stabilize the power feeding the circuit to ensure it works as intended. The working principle of the LNU2H122MSEG aluminum electrolytic capacitors is simple. The electric field between the anode and cathode causes an electric charge to accumulate on the structure of the capacitor. The positive charge is stored on the anode and the negative charge is attracted to the opposite charge on the cathode. The amount of charge the capacitor can hold is determined by its capacitance. This makes it an ideal choice for both filtering and in-circuit decoupling applications.In addition to decoupling, LNU2H122MSEG aluminum electrolytic capacitors can also be used for smoothing and filtering of low-frequency AC signals and in high-frequency stages. The capacitor’s large capacitance makes them an ideal choice for small AC sources at low frequencies. At high frequencies, the capacitance can act as a filter to reduce harmonic distortion.The LNU2H122MSEG aluminum electrolytic capacitors are widely used in many applications. They are commonly found in audio and video applications, motor control circuits, and industrial control systems. They are also very popular for energy storage applications such as in electric vehicles and renewable energy systems. They are often used for decoupling and filtering in power conditioning circuits, too.In conclusion, the LNU2H122MSEG aluminum electrolytic capacitor is a versatile, reliable and efficient capacitor that is widely used in many applications. Its large capacitance range, low profile orientation and hermetic sealed internal components make it an ideal choice for many applications. Its main application is decoupling in audio and video circuits due to its ability to reduce undesirable current spikes and power fluctuations. Its working principle is based on the accumulation of an electric charge between the anode and cathode when an electric field is applied, thus allowing the capacitor to store electrical energy.
