EKMH401VNN471MA45T

Aluminum electrolytic capacitors consist of two aluminum foils separated by a thin paper layer impregnated with an electrolytic solution. The aluminum foils serve as the electrodes of the capacitor, and the electrolytic solution acts as an electrolyte. The anode of the capacitor is connected to one of the aluminum foils, while the cathode is connected to the other. As the current flows through the capacitors, a charge builds up on the anode, creating an electrical field between the two plates. This electric field allows the capacitor to store energy, allowing it to supply the current when it is needed.

The EKMH401VNN471MA45T series capacitors are designed to provide high current density and a wide temperature range of operation. They are constructed with two anodized aluminum foil plates separated by a paper dielectric impregnated with a solvent and electrolyte. The capacitor is also equipped with a built-in snubber, which helps to reduce voltage spikes and thereby minimize power dissipation. The capacitor’s rated capacitance is typically 0.47uF, with a rated voltage of 400V.

These capacitors are most commonly used in switch-mode power supplies, where they are used to smooth out the waveforms of the switch and to soften the edges of the rectifier waveforms. The capacitors also help to reduce the size, weight and cost of the power supply components by providing higher current ratings and wider temperature ranges than traditional aluminum electrolytic capacitors. Additionally, their high current density and low impedance makes them ideal for applications where a low impedance solution is desired.

The EKMH401VNN471MA45T can also be used in a number of other applications, including pulse and digital circuits, timers and oscillators, high-voltage power conversion circuits and audio amplifiers. As with any aluminum electrolytic capacitor, it is important to ensure that the capacitor is selected and operated within its rated range in order to avoid performance and reliability problems. It is also important to note that these capacitors can be damaged by overvoltage, overcurrent and reverse polarity, so it is important to ensure that the application circuit is designed to prevent such conditions from occurring.

The EKMH401VNN471MA45T is an excellent choice for a variety of applications, providing higher current densities and wide temperature ranges than traditional aluminum electrolytic capacitors. The wide range of available sizes and capacitance ratings makes them a versatile choice for many applications, and their reliable operation and longevity make them a popular choice for power supply applications. Additionally, their low impedances make them a great choice for high-voltage applications where a low impedance solution is desired.
