URS1C220MDD

Aluminum electrolytic capacitors have found wide application in many areas such as consumer electronics, audio amplifiers, computers, power supplies and telecommunications since their introduction in the early 1900s. The URS1C220MDD is one such capacitor, and its application field and working principle will be discussed in this article.

The URS1C220MDD is a polarized aluminum electrolytic capacitor. As a type of electrolytic capacitor, it contains two metalized aluminum electrodes which are immersed in an electrolyte – usually a aqueous solution of boric acid or ammonium borate. As the voltage applied to the capacitor increases, so does the space between the positive and negative electrodes, increasing the capacitance accordingly. This makes electrolytic capacitors the ideal choice for applications requiring higher capacitance values within a small form factor, such as the URS1C220MDD.

The URS1C220MDD is a power capacitor, meaning it is designed to handle higher voltages and currents than regular electrolytic capacitors. As such, it is suitable for use in high-power applications such as power supplies, audio amplifiers and inverters. It is also capable of withstanding higher temperatures, making it suitable for high-temperature applications. It also has extended dielectric lifetime, with a maximum operating temperature of 105°C, making it suitable for applications with extended lifecycles.

The nominal capacitance of the URS1C220MDD is 220 μF, and its rated voltage is 25V. Its capacitive tolerance is ±25%, allowing for some variation in values which reduces the risk of failure in applications where exact values are critical. Its lead pitch is 5 mm, making it suitable for use in applications with limited space. The URS1C220MDD is also RoHS compliant, meaning it meets strict environmental performance standards.

In addition to its mechanical properties, the URS1C220MDD also has electrical properties which make it suitable for a variety of applications. Its equivalent series resistance (ESR) is low, meaning it is capable of handling high currents without significant losses. Its ripple current and capacitance stability are also excellent, ensuring that its performance remains consistent over time. Its temperature and frequency characteristics are also good, making it suitable for applications requiring good temporal response.

The URS1C220MDD is a versatile polarized aluminum electrolytic capacitor which is suitable for a variety of applications. Its features and properties make it an excellent choice for high-power and high-temperature applications, as well as those requiring high capacitance values in a small form factor. It also has excellent electrical properties, making it suitable for applications requiring good frequency and temperature characteristics. All of these properties make the URS1C220MDD an ideal choice for use in a wide range of industrial, consumer and professional electronic systems.
