Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is an electrical component made of two aluminum foils that are separated by a thin dielectric layer of oxide. It’s a polarized capacitor and has a positive and negative terminal. It’s used in AC applications because it has a higher capacitance than most ceramic capacitors. With an ability to withstand high temperatures, aluminum electrolytic capacitors are used in a wide variety of applications ranging from power conditioning and power supply circuits to noise suppression and motor control.

UPW1V270MDD6TP Application Field

The UPW1V270MDD6TP is a radial wet tantalum aluminum electrolytic capacitor from Cornell Dubilier. It is a snap-in capacitor with a maximum operating temperature of 85 °C. It has a case size of 11.5mm and a 3500VDC voltage rating. It is rated for 2000hrs at 85 °C and 2000hrs at 40% rated voltage.

This capacitor is typically used in applications such as power supplies and dc to dc converters. It is also used in audio systems, video projectors, and other consumer electronics, as well as igniters and shock absorbers in vehicles.

UPW1V270MDD6TP Working Principle

The UPW1V270MDD6TP is an electrolytic capacitor, meaning the two current-carrying plates are submerged in an electrolyte solution. The plates are made of aluminum and the dielectric layer is made of a very thin layer of aluminum oxide. When a voltage is applied across the plates, ions on the surface of the aluminum gain electrons and deposit on the surface of the other plate.

This deposition of electrons creates a capacitance between the plates, allowing the capacitor to store potential energy in an electrical field. The electrolyte improves the conductivity of the aluminum and increases the amount of charge stored in the capacitor. Over time the buildup of electrons on one of the plates can cause the capacitor to short circuit and fail, so a voltage limiting circuit must be used to limit the voltage going through the capacitor.

Conclusion

The UPW1V270MDD6TP aluminum electrolytic capacitor is a versatile, durable, and efficient electrical component. It is used in a wide variety of applications and can handle a very high voltage. It is constructed out of two aluminum plates covered in a thin oxide dielectric layer, which allows it to store a large amount of charge. The electrolyte improves the electrical conductance, making the capacitor efficient and extending its life.
