Aluminum Electrolytic Capacitors (also known as Aluminium Electrolytic Capacitors) are capacitors that are commonly used in electronic and electrical equipment. They are particularly useful for storing and providing energy in circuits, as well as filtering high-frequency signals. The most common kind of aluminum electrolytic capacitor is the “electrolytic capacitor” or “electrolytic cell” -- a device with two metal plates, a separator, and an electrolyte.The aluminum electrolytic capacitor bearing the designation 381LX151M160H202 is a radial leaded device, typically containing two capacitance values in one unit; 151mF/160V for the working voltage and a lower value of 381mF/160V for the checking voltage. This type of capacitor is usually employed in circuits on the higher voltage side, such as power supplies, AC-DC rectifiers, power converters, and filtering systems.An aluminum electrolytic capacitor works through a process known as “electrochemical replication”, which places two metal plates in an electrolytic solution. When a voltage is applied to the two plates, an electric current is created which flows over a thin layer of aluminum oxide forming on the surface of the plates. The thin oxide layer acts as an insulator, and hence the two metal plates are electrically isolated from each other. Because the oxide layer is extremely thin, it allows electrical charges to be stored on the capacitor plates.This type of capacitor has several advantages when compared to its film and paper counterparts. It exhibits high capacitance (as much as 1000 μF in a single device) and low ESR (Equivalent Series Resistance) at high frequencies due to its design. Furthermore, it has a very good ripple current-handling capability and self-healing characteristics should something go wrong with the device.The capacitance and voltage rating of any aluminum electrolytic capacitor are dependent on its parameter values. The 381LX151M160H202 capacitor has 151mF/160V for its working voltage and a lower value of 381mF/160V for the checking voltage. The working voltage is an indication of how much voltage the capacitor can handle before the oxide starts to breakdown; should the voltage applied to the device exceed the working voltage, then permanent damage might be caused to the device. On the other hand, the checking voltage is an indication of how much voltage can be applied to the capacitor without breaking down the oxide layer. Typical values of the working voltage and checking voltage for other aluminum electrolytic capacitors are typically between 16V and 250V.In conclusion, aluminum electrolytic capacitors, such as the 381LX151M160H202 capacitor, are useful devices in electronics and electrical systems alike. They possess several advantages such as high capacitance, low ESR at high frequencies, good ripple current-handling capability, and self-healing. Furthermore, capacitance and voltage ratings are determined by the parameter values of each individual device.
