476ULR010MEF

Aluminum-polymer capacitors are a subcategory of electrolytic capacitors, and the 476ULR010MEF is one of the most commonly used types. In general terms, capacitors are electronic components that are used to store an electrical charge in order to provide a constant voltage or current to an electronic circuit. An aluminum-polymer capacitor is constructed from two aluminum foils, each having an insulating polymer film in between that acts as a dielectric.
The 476ULR010MEF aluminum-polymer capacitor has a unique construction that allows it to be used in a variety of applications. Firstly, it has a capacitance of 10μF and can operate over a broad temperature range of -55° to +85°C. Furthermore, it has a rated voltage of 4 VDC and a rated ripple current of 3mA. It has a low Equivalent Series Resistance (ESR) of 4 mOhms and an equivalent series inductance (ESL) of less than 10 nH, making it suitable for applications that require high-frequency noise suppression.

In terms of its applications, the 476ULR010MEF aluminum-polymer capacitor can be used for a variety of electronic and electrical circuit applications. It is most commonly used in multimedia and mobile device applications, such as portable MP3 players where it is used to provide a constant voltage or current over a long period of time. In addition, it is suitable for high-frequency applications, such as switching power supplies, where noise suppression is required. It can also be used in temperature measurement and sensing applications.

The working principle of the 476ULR010MEF aluminum-polymer capacitor is based on the fact that when the capacitor is connected to a power supply, electrons begin to move between its two terminals, creating an electric field. This electric field is established between the two terminals and its strength is determined by the capacitance of the capacitor as well as the applied voltage. The current that flows through the capacitor is inversely proportional to its capacitance, i.e., the higher the capacitance, the lower the current. The capacitor stores electrical energy by charging and discharging, and can provide a sustained voltage or current to the circuit.

In conclusion, the 476ULR010MEF aluminum-polymer capacitor is a highly reliable, versatile capacitor that is suitable for a wide range of applications. It offers a wide working temperature range, low ESR and ESL, and high capacitance, making it suitable for high-frequency applications. It also has a versatile design allowing it to be used in a variety of applications, such as portable audio devices, temperature measurement and sensing circuits, and switching power supplies.
