Introduction

 Aluminum electrolytic capacitors are widely used in modern electronic devices due to their low cost and wide availability. The ULD2G2R7MPD1TA is an example of a common aluminum electrolytic capacitors (AEC) with general characteristics typical of these components. This article will discuss the application field and working principle of ULD2G2R7MPD1TA.

Application Field

 The ULD2G2R7MPD1TA capacitor is mainly used in regulating voltage, filtering, and coupling applications in the range of -40°C to 85°C. Its application fields are mainly automotive, telecommunications, medical and industrial systems.

 This capacitor offers a wide range of features that make it appropriate for many applications. It is available in a variety of sizes, ranging from 10μF to 4.7F. It has an operating temperature range of -40°C to 85°C, and its capacitance tolerances can vary from ±10% to ±20%. It also has a rated voltage from 2.5V to 50V and a voltage derating of 0.63V/°C. With a lifetime of up to 10,000 hours at 85°C, it is well suited for prolonged use.

 In addition, the ULD2G2R7MPD1TA has a maximum ripple current rating of 80mA per 1μF. This ensures a stable current supply, making it suitable for several types of regulated and unregulated power supply applications.

Working Principle

 The ULD2G2R7MPD1TA capacitor is an electrolytic capacitor, a type of capacitor that stores energy in an electrolyte-soaked separator between two metal electrodes. This capacitor is constructed of an electrochemically activated anode and a non-activated cathode. The anode is usually made from a metal with high conductivity, such as aluminum, and is coated with an oxide layer that serves as an insulator and a capacitor dielectric. The cathode is usually a conductive metal plate or wire.

 When a voltage is applied across the capacitor, the anode becomes positively charged, and the cathode becomes negatively charged. This causes a layer of electrons to move from the anode to the cathode, creating a build-up of positive and negative charges. This charge build-up creates a stored electrical field and generates a capacitance, which is calculated as the ratio of the applied voltage to the charge stored in the capacitor.

 The ULD2G2R7MPD1TA capacitor has a high capacitance-to-volume ratio, making it an ideal choice for low-profile devices. The capacitor is also resistant to aging and is suitable for harsh environments.
