Aluminum electrolytic capacitors are a type of polarized capacitor that has an anode of pure aluminum foil, a cathode of etched aluminum foil, and a liquid electrolyte as its dielectric. UKZ2A470MHM is an aluminum electrolytic capacitor manufactured by TDK Corporation. This capacitor has a high capacitance of 470μF, a rated voltage of 35V, and a maximum operating temperature of 105°C. The capacitor is a reflow-compatible, top-radial type that comes in a SP series radial case.

Aluminum electrolytic capacitors are widely used in many applications as they provide a variety of features such as high capacitance, high voltage ratings, low impedance, long life, and low leakage current. UKZ2A470MHM is an ideal capacitor for use in motor control, power factor correction, energy storage, and power supply applications. This capacitor is also well-suited for use in consumer electronics, automotive, lighting, and other industrial applications.

The working principle of an aluminum electrolytic capacitor is based on the electrolytic process. The electrolyte serves as an electrolytic medium and the aluminum foil serves as electrodes for the capacitor. When a voltage is applied, electrons flow from the negative (-) terminal to the positive (+) terminal. The movement of the electrons causes a polarization of the electrolyte and generates a capacitor with a dielectric that is made up of two layers. The first layer is an oxide layer on the surface of the aluminum foil, while the second layer is a thin layer of the electrolyte inside the capacitor.

The oxide layer serves as the dielectric, allowing current to flow through the capacitor while blocking the flow of electrons. The electrolyte provides ions to restore the charge of the capacitor. This makes it possible for the capacitor to retain its charge over a long period of time. The composition of the electrolyte affects the capacitance, leakage current, and maximum operating temperature of the capacitor.

This UKZ2A470MHM aluminum electrolytic capacitor has a long service life of up to 5000 hours. It has a low equivalent series resistance (ESR) of 7.4mΩ, which allows for a low impedance operation. The capacitor also has an endurance of 2000 hours of continuous operation at its rated temperature of 105°C and voltage of 35V.

The UKZ2A470MHM aluminum electrolytic capacitor is a reliable and efficient capacitor that has many advantages. It has a high capacitance, a high voltage rating, a low ESR, a long life, and a low leakage current. It is a suitable choice for many applications including motor control, power factor correction, energy storage, power supply, consumer electronics, automotive, lighting, and other industrial applications.
