EET-HC2V471KF

Aluminum Electrolytic Capacitors are widely used in different areas, such as high-frequency switching power supplies, power supplies for computer motherboards, LCD TVs, LED backlight systems, and medical power supplies. The EET-HC2V471KF is one of the most common models of aluminum electrolytic capacitors. This article will describe the application field and working principle of the EET-HC2V471KF.

The EET-HC2V471KF is a radial lead, snap-in electrolytic capacitor. It is rated at 4.7µF, 16V dc, and 22000 hours @ 105°C. It is designed with aluminum foil as the anode and electrolyte as the cathode. The aluminum foil is perforated and electrolyte is impregnated into the pores. It has a very short rise time, making it suitable for use in high frequency circuits where high current is required. The cap also has low internal resistance, low ESR and ESL, making it ideal for circuits where low inductance and low impedance is required.

The EET-HC2V471KF can be used for various applications, including power-supply circuits, decoupling circuits, snubber circuits, and a variety of filtering applications. It can also be used as a bypass or energy storage capacitor in RF circuits. Its aluminum electrolyte offers the highest possible capacitance per volume compared to other types of capacitors and is suitable for larger capacitance values in the same footprint. The EET-HC2V471KF is also suitable for high pulse current applications, due to its very low ESR and ESL.

The working principle of the EET-HC2V471KF is simple. When the anode is subjected to a positive voltage, a current flows from the aluminum foil to the electrolyte. This current causes ions to deposit on the aluminum foil, creating a dielectric film. This dielectric film prevents further current flow and effectively divides the capacitor into two plates of opposite charges. As the two plates are now forming a capacitance, stored energy can be delivered to the circuit.

The EET-HC2V471KF is an ideal choice for high-frequency circuits where high current is required. Its aluminum electrolyte offers the highest possible capacitance per volume, low internal resistance, low ESR and ESL, making it suitable for a number of applications. It is the perfect choice for decoupling circuits, snubber circuits, and various filtering applications.
