Aluminum Electrolytic Capacitors and the UBC1H681MNS1ZD

Aluminum electrolytic capacitors, sometimes referred to as a type of electrolytic capacitor or simply an electrolytic, are capacitor components that utilize an electrolyte, typically in paste or liquid, and two electrodes, one of which is usually a metalized aluminum surface. As voltage is applied, current passes between the electrodes, forming a thin layer of dielectric oxide on the aluminum surface. This double layer of insulation forms the basis of the capacitance of the capacitor.

The UBC1H681MNS1ZD is a high-capacitance, low-profile, aluminum electrolytic capacitor featuring a ‘snap-in’ terminal and solderable EIA4/M4 base. The maximum working voltage of this capacitor is 6.3V, the capacitance ranging from 0.22µF to 470µF with a ±20% tolerance. It has a surge voltage of 8.5V and a maximum peak working voltage of 8V. It also has a temperature coefficient of ±30ppm/°C, a leakage current of 0.1CC or 4.5μA, and a maximum operating temperature of 125°C.

The UBC1H681MNS1ZD is typically used in general circuit applications, as it can be used in many consumer products including computer peripherals, digital appliances, power supplies, mobile phone chargers, camera modules, and automotive and industrial equipment. This capacitor is also known for its high ripple current characteristics, making it particularly suitable for energy storage in high-frequency applications. This enables it to provide high levels of capacitance without compromising on the reliability of the capacitor.

The UBC1H681MNS1ZD utilises the same working principle as other aluminum electrolytic capacitors. Inert electrodes are separated by a thin layer of insulating material, known as the dielectric. This dielectric is typically a special, semi-conducting oxide layer formed on the aluminum surface. The main advantages of these types of capacitors is that they can store relatively large amounts of electrical energy in a relatively small package.

When AC voltage is applied between the two electrodes, electrical charges will build up in the capacitor as they are not able to flow between the two electrodes due to the dielectric layer. When DC voltage is applied, the electrons will flow through the circuit forming electron flow between the electrodes, and the capacitor becomes charged and stores energy.

When current flows through the capacitor, the electrochemical reaction between the electrodes and electrolyte will generate heat. Heat generated by this electrochemical reaction is proportional to the current; hence, it is important to first calculate the current required and use capacitors with suitable current-handling capabilities.

When the voltage across the capacitor\'s terminals is reversed, the stored electrical energy is dissipated, and the same electrochemical reaction between the electrodes is reversed. This causes the capacitor to discharge which results in a drop in voltage and an increase in current. The rate at which these changes occur is dependent on the resistance of the external circuit, with lower resistance resulting in faster discharge.

In summary, the UBC1H681MNS1ZD is a high-quality aluminum electrolytic capacitor with a low profile that has a wide variety of applications in various consumer products. With its high ripple current and low temperature coefficient, it can be used in a broad range of high-frequency energy storage applications. Its working principle is similar to other aluminum electrolytic capacitors with electrodes separated by an insulating dielectric layer. When an AC or DC voltage is applied, charges build up and stored electrical energy is dissipated when the voltage is reversed.
