Aluminum electrolytic capacitors (AECs) are one of the most widely used capacitors in electronic devices, and the LKG1J472MESAAK model is no exception. This capacitor is mainly used in AC applications, in part due to its high capacitance and rated voltage. The rated voltage of the LKG1J472MESAAK model is 400Vdc, and the ripple current capability is 3.4A.

An aluminum electrolytic capacitor is an electronic component that stores energy in a thin layer of aluminum oxide which forms on the surface of its anode plate. Inside the anode is a porous layer that allows ions to move back and forth between electrolyte material and the anode. This gives the capacitor the ability to hold a static charge. The main difference between AECs and regular capacitors is that AECs tend to have a higher capacitance than standard capacitors (due to the presence of the electrolyte layer), and they often also have a much longer life than regular capacitors.

The LKG1J472MESAAK is a radial aluminum electrolytic capacitor, meaning it will have two leads protruding from the side of its case. The leads are soldered to the circuit board, and the entire assembly is then put inside the enclosure of the device where it will stay completely sealed. This ensures that no moisture, dust, or foreign contaminants enter the capacitor, and it has a long life. The LKG1J472MESAAK is also a snap-on terminal, which makes it easy to attach to the circuit board.

The LKG1J472MESAAK aluminum electrolytic capacitor can be used in a variety of AC applications, like AC ripple suppression and DC blocking. It can also be used in audio oscillators, AC-DC converters, frequency division circuits, and more. The rated temperature range of the LKG1J472MESAAK is -40°C to +105°C, which makes it ideal for applications that require high operational temperatures.

The working principle of the LKG1J472MESAAK aluminum electrolytic capacitor is that it stores electric energy in the form of a static charge. The static charge is produced by the electrolyte present in the anode plate and is created when ions from the electrolyte form an oxide layer on the anode. This oxide layer then acts as a barrier between the electrolyte and the metal anode, which prevents the charge from dissipating. Each time a voltage is applied to the capacitor, the oxide layer forms a capacitive barrier, and this allows electric energy to be stored.

When the voltage is removed, the oxide layer dissipates and the capacitance decreases. This is why aluminum electrolytic capacitors have a limited lifetime – over time the oxide layer that forms on the anode plate gradually dissipates, and the capacitor’s capacitance is decreased. This means that the capacitor must be replaced after a certain period of time.

The LKG1J472MESAAK aluminum electrolytic capacitor is an excellent choice for a variety of AC applications due to its high capacitance and rated voltage. Its snap-on terminals make it easy to install, and its range of working temperatures make it suitable for applications where high temperatures may be experienced. The working principle of the capacitor is based on the formation of an oxide layer on the anode plate, which gives it the ability to store electric energy. This makes the LKG1J472MESAAK an excellent choice for AC applications that require high capacitance and rated voltage.
