UVZ1V470MDD1TD Capacitors

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrochemical capacitors that use an electrolyte to achieve a larger capacitance in a very small space compared to a film or ceramic capacitor. This class of capacitor has the highest maximum allowable voltage, which is twice that of tantalum and much higher than that of ceramic and plastic capacitor cases.

The UVZ1V470MDD1TD capacitor is an aluminum electrolytic capacitor from Murata Manufacturing Co. Ltd. This particular series is designed for harsh conditions, and its aluminum etched terminal technology increases overall robustness for operating temperatures as high as 110°C. It has a long life rating of 5,000 hours, a high pressure-resistance performance of 8.2kV, and a small size of 6.3×7.7mm.

Applications

Aluminum electrolyte capacitors have a wide range of applications. They are typically used in circuits that require filtering or high-frequency smoothing of power or that require decoupling of power lines. They are also sometimes used to store energy in devices such as camera flashes, robots and automotive electronics.

The UVZ1V470MDD1TD capacitor is specifically designed for high-reliability applications that require long life and high pressure-resistance performance. The capacitor is well suited to the automotive industry and can withstand harsh environmental conditions such as temperature cycling and exposure to oils and fuels. It is also well suited to applications such as power supplies, motor controls and UPS systems.

Working Principle

The working principle of aluminum electrolytic capacitors is similar to that of traditional capacitors. An anode made of aluminum foil is covered with an electrolyte-soaked paper, and the cathode is connected to a tab in the bottom. When a voltage is applied, ions from the electrolyte move towards the anode and form an electric double layer called the Helmholtz Layer. This increases the capacitance of the capacitor.

Unlike ceramic or plastic capacitors, aluminum electrolytic capacitors have a much larger capacitance for their size. This is due to the use of an electrolyte, which increases the surface area of the anode and thus the amount of ions that can be held. This allows for a higher capacitance for a given size, which is the primary benefit of aluminum electrolytic capacitors.

Conclusion

The UVZ1V470MDD1TD aluminum electrolytic capacitor is an ideal choice for high-reliability applications such as automotive electronics and power supplies. It has a long life rating of 5,000 hours and a high-pressure resistance of 8.2 kV, making it well suited to harsh environments. The working principle of an aluminum electrolytic capacitor is similar to that of traditional capacitors, but the use of an electrolyte allows for a much larger capacitance in a very small space.
