Aluminum Electrolytic Capacitors

UPH2W151MHD application field and working principle

Aluminum electrolytic capacitors are a type of capacitor with a solid electrolyte consisting of an aluminum foil with a layer of insulating paper, and a layer of liquid electrolyte in contact with the aluminum foil. They are used extensively in power supplies and signal processing circuits, and come in a variety of form factors, both radial and axial leads. These capacitors can be characterized by their voltage ratings, capacitance tolerance, ripple current, and their ESR.

The UPH2W151MHD is a cylindrical aluminum electrolytic capacitor from Nichicon, one of the leading manufacturers of capacitors and other electrical components. It is rated for a maximum working voltage of 150V, and a capacitance of 470μF. It has a ripple current capability of 1.2A and its ESR is 1.1Ω. The capacitor is designed for use in a wide range of applications, from general purpose signal filtering, to motor drive applications and AC power supplies.

The UPH2W151MHD operates on the principle of Faraday’s law of electrolysis. When a voltage is applied across a capacitor, it acts to store charge on the two plates separated by an insulation, or dielectric. The presence of the dielectric material can be thought of as resistance, and the charge is stored on both the positive and negative plates of the capacitor. In an electrolytic capacitor, one of the plates is an electrolyte, and the other is a metal surface. When an external voltage is applied, an electric field is created across the plates, causing ions in the electrolyte to move to the metal surface, forming a deposit of charged material which increases the capacitance of the device. This deposited material is a combination of the metallic ions in the electrolyte and the electrons from the external voltage source.

In the case of the UPH2W151MHD, the capacitor is designed with a high quality liquid electrolyte. The combination of the low ESR and the high capacitance of the device make it ideal for many applications, from general purpose signal filtering to motor drives and AC power supplies.

The UPH2W151MHD aluminum electrolytic capacitor is one of the most popular devices used in a wide range of applications. Its low ESR and high capacitance make it suitable for a variety of applications, from general purpose signal filtering to motor drive and AC power supplies.

In conclusion, the UPH2W151MHD aluminum electrolytic capacitor is an excellent choice for a wide range of applications. Its high capacitance and low ESR make it suitable for a variety of applications, from general purpose signal filtering to motor drives and AC power supplies.
