EKMH451VNN221MR35W Datasheet/PDFAluminum electrolytic capacitors consist of an aluminum oxide layer formed on the surface of aluminum foil, which is the medium for storing energy in the form of an electric field. At the same time, it contains electrolyte filled in it. It is the basic structure of aluminum electrolytic capacitors. The capacitance of aluminum electrolytic capacitors has wide range and large capacity, so it has been widely used in electronic products.
The aluminum electrolytic capacitor model EKMH451VNN221MR35W is one of the main products of aluminum electrolytic capacitors. This product is a high voltage-stability capacitor with a working voltage of 455 VDC, a working temperature of - 40 ° C ~ + 105 ° C, and a capacitance of 0.01 μF ~ 0.47 μF. It also has excellent low-temperature characteristics and can be used even when the environment is extremely cold. The EKMH451VNN221MR35W has an increased capacity at a given voltage, which reduces the cost of the overall product.
In terms of application field, the EKMH451VNN221MR35W is widely used in high temperature and large capacity electronic products, such as high power audio amplifiers in automobiles and consumer electronics. It can not only provide stable capacitance and high temperature performance but has low equivalent series resistance (ESR), which can reduce the high frequency ripple current on the output of the circuit. Therefore, a high power audio power amplifier that requires large capacitance and can withstand high temperature is relatively suitable for the EKMH451VNN221MR35W.
The working principle of the EKMH451VNN221MR35W is mainly based on the principle of electrolytic capacitance. When the capacitor is applied with a negative voltage, the conductive electrons are attracted to the positive plate by the negative voltage, forming a negative charge on the negative plate. When a positive voltage is applied, the conductive electrons will be repelled by the positive voltage, forming a positive charge on the positive plate, so that the potential difference between the two plates will be formed to store electric energy.
In general, the EKMH451VNN221MR35W is a high temperature, high voltage-stability product of aluminum electrolytic capacitors, which has excellent characteristics such as stable capacitance and low equivalent series resistance (ESR). It is widely used in high power audio amplifiers in automobiles and consumer electronics. Its working principle is mainly based on the principle of electrolytic capacitance.
