Aluminum electrolytic capacitors are polarized capacitors with a larger capacitance per unit volume than other capacitor types. These capacitors are commonly used in electronic circuits because of their small size, high capacitance, low cost, and reasonable service life. There are various types of aluminum electrolytic capacitors with different properties and applications, and in this article we will focus on a specific type: the URS1A471MPD1TD.

The URS1A471MPD1TD is a snap-in, aluminum electrolytic capacitor with non-solid electrolyte. It is rated 105°C and 400V, and has a low equivalent series resistance (ESR) of 0.003ohm [-40°C~105°C]. This capacitor has a capacitance range from 100μF to 4.7mF, and its capacitance tolerance can be as low as ±20%.

The main application of the URS1A471MPD1TD is in power supplies, including DC-DC converters and PC power supplies. It is also commonly used in power supplies for industrial and domestic electrical equipment, as well as desktop computers, servers, and other types of electronic devices. It is suitable for decoupling, filtering, and signal transmittal, and has a high ripple current capability.

The working principle of the URS1A471MPD1TD is based on the principle of electrolytic capacitors, whereby two electrically conductive surfaces are separated by a dielectric oxide layer. This oxide layer is maintained by an electrolyte, which is generally an acidic solution. As an electric current passes through the capacitor, an electrical field is created which causes the oxide layer to grow or shrink, thereby controlling the capacitance of the capacitor. The voltage rating of the capacitor is determined by the thickness of the oxide layer.

In summary, the URS1A471MPD1TD is an aluminum electrolytic capacitor suitable for DC-DC converters, PC power supplies, and other power supplies. It has a low ESR, a capacitance range of 100μF to 4.7mF, and a high ripple current capability. Its working principle is based on the principle of electrolytic capacitors, whereby an electric current creates an electrical field that controls the capacitance of the capacitor.
