ULD2D4R7MED1TA

Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors, often known as aluminum capacitors, are a type of capacitor that uses an electrolyte, typically a liquid or gel, as the dielectric instead of a solid plastic film. This type of capacitor has a wide range of working temperatures, and very high capacitance values.

ULD2D4R7MED1TA application field and working principle

The ULD2D4R7MED1TA is an Aluminum Electrolytic Capacitor used in a wide variety of applications, including power supplies, rheostats, switching regulators, motor control, audio power supplies, and audio noise suppression. It is a four-terminal device, meaning it has two input terminals, two output terminals, and a common ground. It also has an internal diode to protect against reverse surges.

The working principle of the ULD2D4R7MED1TA is fairly simple. It is created by adding an electrolyte, such as aluminum oxide, between two conductive plates. When a voltage is applied across the plates, the electrons move from the negative plate to the positive plate, creating a current flow. This current flow is then used to create a charge on the capacitance plates, which stores an electrical charge.

The ULD2D4R7MED1TA is a low-ESR capacitor, meaning it has a low equivalent series resistance. This makes the capacitor ideal for applications where low noise, high frequency, and ripple currents are needed. As a low-ESR capacitor, it is also able to reduce EMC noise, making it ideal for applications where EMC noise suppression is required.

Overall, the ULD2D4R7MED1TA is an ideal capacitor for many types of applications that require high performance and reliability. The low equivalent series resistance combined with its wide temperature range makes it a desirable choice for many different applications.
