Introduction

Aluminum electrolytic capacitors are widely used due to their extremely high capacitance and excellent price/performance ratio. As its name suggests, they contain an electrolyte, usually an etchant, and a solid aluminum oxide dielectric. The capacitance of an electrolytic capacitor is a function of its surface area, and as such, they have extremely high capacitance values.

UPW1C121MEH Application Field

The UPW1C121MEH is an aluminum electrolytic capacitor that is ideal for use in automotive, industrial, and consumer electronics applications. It is rated for a capacitance of 1200 microfarads, and has a maximum operating temperature of 105°C. The operating temperature range for this device is -55°C to +105°C.

The UPW1C121MEH is designed for use in applications such as battery chargers, motor drives, lighting, and HVAC systems. It is also well suited for UPS systems, as it has improved AC ripple current capabilities. As an aluminum electrolytic capacitor, the UPW1C121MEH has low ESR values and excellent high frequency characteristics, making it ideal for applications that require fast transient response.

UPW1C121MEH Working Principle

The UPW1C121MEH is an aluminum electrolytic capacitor, which means it uses an aluminum foil and an electrolyte as its dielectric. When a voltage is applied to the capacitor, a layer of aluminum oxide is formed on the aluminum foil. The formation of this layer is known as anodic oxidation. The oxide layer acts as an insulator, allowing the capacitor to store charge even after the voltage is removed.

The layer of aluminum oxide also determines the capacitance of the capacitor. The capacitance of an electrolytic capacitor is a function of its surface area, and as such, aluminum electrolytic capacitors have extremely high capacitance values compared to other types of capacitors.

The UPW1C121MEH also has improved AC ripple current capabilities compared to other types of capacitors. This is due to its low ESR values and higher frequency characteristics. These features make the UPW1C121MEH ideal for applications that require fast transient response.
