Aluminum electrolytic capacitors are useful electronic components in various consumer and industrial applications. The UTM1H4R7MPD1TD is a passively polarized aluminum electrolytic capacitor with a 4.7uF rating, a voltage rating of 25V, and a ceramic case size of 12.5 × 19.3 mm. It is designed for operation in either AC or DC circuits and is suitable for a wide range of applications, including power supplies, motor drives, energy storage, audio, and automotive electronic product applications.

To understand the UTM1H4R7MPD1TD application field and working principles, let’s first discuss the basics of how an electrolytic capacitor works. An electrolytic capacitor is composed of two metal plates separated by a passivation layer which acts as an electrical insulator. One plate is made of aluminum or other metallic material and is used as the anode, while the other plate is made from a metal oxide dielectric material and serves as the cathode. The anode is connected to the positive terminal of the capacitor, while the cathode is connected to the negative terminal. A liquid electrolyte, usually composed of sodium hydroxide or potassium hydroxide, is used to complete the circuit.

The working principle of the UTM1H4R7MPD1TD is based on the capacitance effect of the two electrodes in an electrolyte solution. When charged, the capacitor is able to store and release energy as required. The charged anode creates an electrical field due to the accumulation of positive charge, while the negative charge on the cathode generates an electrical field in the opposite direction. As the two fields interact, a transfer of energy occurs, causing the anode and cathode to become charged and discharged, respectively. This process is called capacitive energy storage.

The UTM1H4R7MPD1TD is designed to provide stable performance and reliability in a wide range of applications, including those requiring high temperature and/or high frequency electrical noise suppression. Its 4.7 μF rating provides a moderate amount of capacitance, enough to handle most general purpose electronic applications. Its rated voltage isn’t particularly high compared to other types of electrolytic capacitors, making it suitable for most household and automotive electronics. Additionally, the ceramic case it comes in is relatively small compared to other types of electrolytic capacitors, making it ideal for use in cramped spaces.

Due to its reliability and size, the UTM1H4R7MPD1TD is suitable for a wide range of applications, such as motor drives, energy storage, AC/DC converters, audio, and power supplies. It is also a great choice for automotive applications, where the small size and modest capacitance rating can help save precious space and reduce costs. Furthermore, its low impedance is beneficial for high frequency applications, such as audio filters and resonators.

In summary, the UTM1H4R7MPD1TD is a passively polarized aluminum electrolytic capacitor with a 4.7uF rating, suitable for use in both AC and DC circuits. Its rated voltage is relatively low compared to other types of electrolytic capacitors, making it suitable for most household and automotive electronics. Its small case size makes it ideal for use in cramped spaces. Thanks to its reliability and design, the UTM1H4R7MPD1TD is a great choice for a wide range of applications, such as motor drives, energy storage, AC/DC converters, audio, and power supplies, as well as automotive electronics.
