ECE-A0JN470UB Datasheet/PDFAluminum electrolytic capacitors consist of two electrodes separated by a layer of aluminum oxide. The anode is a thin aluminum foil onto which a porous aluminum oxide layer is grown. The anode is etched to form a group of parallel strips. Such a configuration will create a higher capacitance. Between these strips, a thin layer of electrolyte is sprayed, and then the cathode foil is attached which also acts as the terminal for external connections. These capacitors are constructed using manganese dioxide or a solid polymer electrolyte.The ECE-A0JN470UB is an Aluminum Electrolytic Capacitor that is used for various applications. These include power lines, reverse polarity protection, and noise suppression. It is a high-voltage capacitor with a voltage rating of 1250Vdc. The ECE-A0JN470UB has a wide temperature range and works in both extreme temperatures. Furthermore, it has a capacitance of 470uF and an equivalent series resistance (ESR) of 0.25 ohms at 1KHZ.
The ECE-A0JN470UB is mainly used in power filters, where it helps to reduce noise and protect the connected components from high voltage spikes. It is also used in audio crossover networks due to its fast response time and high capacitance. Additionally, the capacitor can be used in defibrillators and plasma TV boards. Indefibrillators, the capacitance helps in providing the necessary electrical surge for defibrillation, while in plasma TVs, it helps to limit voltage surges that may otherwise damage the electronics.
The working principle of the ECE-A0JN470UB is based on the Faraday’s law of electrolysis. This principle states that when a voltage is applied across an electrolytic capacitor, an electric current will be passed through the electrolyte between the two electrodes, making the capacitor charged or discharged. The capacitance of the capacitor is inversely proportional to the voltage applied across it. When a higher voltage is applied, it creates a larger electric field between the two electrodes, increasing the capacitance of the device. This principle is used in the ECE-A0JN470UB to provide high capacitance values and fast response times.
The ECE-A0JN470UB is a reliable and cost-effective capacitor that is suitable for many applications. It can operate in extreme temperatures and provides high capacitance values with low ESR for a wide range of power filters. Furthermore, its fast response time makes it ideal for audio crossover networks and other sensitive applications. Therefore, it is a valuable component in numerous applications.
