URS1A220MDD1TD Capacitors

Aluminum electrolytic capacitors, or simply electrolytic capacitors, are electrochemical capacitors in which the electrolyte acts as the anode and the two conductive plates are a separator and a cathode. The URS1A220MDD1TD is one such aluminum electrolytic capacitor commonly used in AC power supplies and DC power circuits. It features a long life and low temperature coefficient over a wide temperature range, making it suitable for various applications requiring reliable performance.

The URS1A220MDD1TD is composed of an anode made of aluminum foil, a separator made of dielectric (glass) or plastic, and a cathode made of organic film. The organic film is the active material in this capacitor, providing its electrical energy storage capability. It consists of a negative pump layer and a positive polarizable layer.

The URS1A220MDD1TD has a wide working voltage range of 6.3V to 400V and a capacitance of 220uF. The capacitor is rated for an operating temperature of -40°C to +85°C, making it suitable for use in many applications such as snubber circuits, wave filtering and RC filters. It has a maximum ripple current at 0.85V of 11.32A RMS, giving it a long life compared to other capacitors.

The working principle of the URS1A220MDD1TD is based on the principle of electrochemical double layer capacitor (EDLC). When a voltage is applied across the device, ions are injected in the electrolyte and a double layer forms on the anode surface. This double layer stores electric energy and acts as an additional capacitance, increasing the total capacitance of the device. The device can thus store energy and release it when needed.

The URS1A220MDD1TD can be used in various applications requiring reliable performance. It is suitable for AC power supplies, DC power circuits, wave filtering, snubber circuits and RC filters, among other applications. It also has a long life and low temperature coefficient over a wide temperature range, making it ideal for many industrial applications.

In conclusion, the URS1A220MDD1TD aluminum electrolytic capacitor has a wide variety of application fields and works on the principle of EDLC. It has a long life and low temperature coefficient over a wide temperature range, making it suitable for various applications requiring reliable performance.
