Introduction

Aluminum electrolytic capacitors are passive electronic components used to store energy in an electric field. They are constructed with two aluminum foils, which are covered with an insulating material and outfitted with electrical leads. The leads are then immersed in an electrolyte, which is typically a liquid or paste made up of a combination of acids, water, glycols, and other components. Due to their construction, aluminum electrolytic capacitors have a wide range of applications in the electronics industry.

UVY2GR47MED1TD Application Field and Working Principle

The UVY2GR47MED1TD is a type of aluminum electrolytic capacitor developed by Vishay Semiconductor specifically for use in automotive electronics. The UVY2GR47MED1TD is designed for extreme conditions such as high temperatures, high voltages, and rough vibration. Due to its design, it is highly suitable for use in applications requiring reliability and high performance such as engine control, motor control, lighting, infotainment, and telematics.

The working principle behind the UVY2GR47MED1TD is based on the use of electrodes and electrolyte. In a typical application, an aluminum plate is covered with an insulator and two electrodes are attached, one to each side of the plate. When a voltage is applied, the electrolyte provides an electrical path between the two electrodes, allowing electrons to flow through the electrolyte. The electrons move from one electrode to the other and result in a buildup of charge in the capacitor.

The capacitance of the capacitor depends on the area of the plates, their distance apart, and the dielectric constant of the electrolyte. The dielectric constant is related to the electrical resistance of the electrolyte and can vary depending on the electrolyte and the voltage applied. As the voltage increases, the capacitance of the capacitor decreases.

The UVY2GR47MED1TD is designed for harsh environments and operates in temperatures from -40 to +125°C and has an operating voltage range of 16V to 150V, and an operating temperature range of -25°C to +85°C. This makes it ideal for automotive applications that require high levels of performance and reliability.
