Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most widely used components in electrical and electronic applications. They are generally used to store electric charge and to provide an electrical path of varying resistance, capacitance, and inductance in order to control the current or voltage in a circuit.

UHD1A101MDD application field and working principle

The UHD1A101MDD is a surface mount aluminum electrolytic capacitor that is ideal for a variety of applications. It is a non-polarized aluminum electrolytic capacitor with very low impedance and long useful life. The ceramic capacitor features high capacitance, long useful life, low temperature coefficient and high reliability. It is commonly used in switches, power supplies, computers, amplifiers, and other electrical and electronic applications.

The working principle of an aluminum electrolytic capacitor is based on an electrochemical reaction between an anode composed of an aluminum electrode covered with an oxide layer, a cathode composed of a liquid electrolyte, and a paper or plastic separator between them. When the capacitor is supplied with an initial voltage, ions from the electrolyte start to accumulate on the surface of the anode, which increases its surface area. Since the surface area of the anode is directly proportional to the capacitance of the capacitor, this increases the capacitance of the capacitor.

The UHD1A101MDD has a wide operating temperature range of –55 to +110 °C and has a capacitance of 10 µF with a rated DC voltage of 16 VDC. It also features low ESR (equivalent series resistance), which translates to higher ripple current and superior temperature characteristics. The specification sheet also notes that the “UHD1A101MDD uses solid electrolyte, which offers higher reliability and longer lifespan than the standard anode electrolytic capacitor.”

The UHD1A101MDD aluminum electrolytic capacitor is designed for high voltage applications. It is ideal for use in small space, high density applications such as DC-DC converters, LED lighting, power management, large displays, and other electronics. It is also suitable for motor drive applications, motor control circuits, voltage converter controllers, and switching power supplies.

Aluminum electrolytic capacitors, such as the UHD1A101MDD, are known for their superior reliability, long useful life and high capacitance compared with other types of capacitors. They have design features that give them greater stability and better life expectancy. They are cost-effective and offer excellent performance in applications where precision energy storage and reliable operation is required.
