UKL1J470KPD

Aluminum electrolytic capacitors are a type of capacitor that uses two pieces of aluminum foil which act as the plates and an electrolyte, often acidic in nature, to separate them. The electrolyte forms a thin dielectric layer between the two plates and helps store electrical energy. The most common type of electrolytic capacitors are made from either tantalum or aluminum, and each type has different application fields and working principles.

The UKL1J470KPD is an aluminum electrolytic capacitor which is primarily used in filtering applications. It has a maximum operating temperature of 105°C, a capacitance tolerance of ±20%, and a lifetime of 2,000 hours. The main features of this type of capacitor are low ESR, low ripple current, high reliability, and a large capacitance range. This makes them ideal for filtering applications such as noise suppression in audio systems, EMI/RFI filtering, power line conditioning, power supply decoupling, motor drive filtering, and many other applications. It is also used as an oscillator or timer due to its low ESR.

The working principle of an aluminum electrolytic capacitor is relatively simple. It is a polarized device which means one of the two plates must be connected to the positive side of the power source, and the other one to the negative side. When this is done, the applied voltage causes a current to flow through the electrolyte between the two plates. This leads to the formation of a thin dielectric layer between the two plates which helps store electrical energy. The thickness of this dielectric layer is determined by the applied voltage, and the amount of energy that can be stored is determined by the capacitance of the device.

In conclusion, the UKL1J470KPD belongs to the category of Aluminum Electrolytic Capacitors, and is typically used in filtering applications. Its main features include low ESR, low ripple current, high reliability, and a large capacitance range. Its working principle is that of any other aluminum electrolytic capacitor, which involves the flow of current through the electrolyte between the two plates which helps store electrical energy.
