478LBB050M2DC

Aluminum electrolytic capacitors are widely used in power supplies, monitors, audio and video equipment and automatic control systems. 478LBB050M2DC is a type of aluminum electrolytic capacitor with distinct characteristics that differentiates it from other aluminum electrolytic capacitors. It is usually used in switching power supplies, communication equipment and consumer electronics.

The 478LBB050M2DC aluminum electrolytic capacitor has a diameter of 22.5mm, a length of 25.8mm and a 0.5 400V rated voltage. The outer shell is designed with a can design, which has good anti-corrosion and insulation performance and is safe and reliable in use. As an aluminum electrolytic capacitor, 478LBB050M2DC has excellent characteristics in terms of temperature, reverse leakage current, and failure rate. Its low working temperature is between -40 and +105 degrees Celsius and its working humidity is from 85% to 95%. In addition, 478LBB050M2DC has a reversing current of ≤5.6 μA and a failure rate of 0.0005%.

The working principle of 478LBB050M2DC is that there are two electrodes placed in an electrolyte. The positive pole is connected to the anode made of aluminum foil and the negative pole is connected to the cathode made of a metal oxide film. When a DC voltage is applied to the two electrodes, an electric field is generated and a layer of aluminum oxide is formed on the surface of the anode. This creates an insulating film on the anode, and it helps to increase the capacitance of the capacitor. After this, when a voltage is applied to the two electrodes, a current will flow, and the current is blocked by the insulating film, resulting in only a small amount of current flowing, thus creating a "capacitance" that stores energy.

Thus, 478LBB050M2DC aluminum electrolytic capacitors are mainly used in a variety of switching power supplies, communication and precision equipment and consumer electronics. Its advantages of low temperature, reverse leakage current and failure rate make it a preferred choice in these applications.
