Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor that uses electrolysis, with an anode consisting of an aluminum foil covered with an oxide layer that acts as an insulator, and a cathode made of aluminum foil that acts as a conductor. These capacitors are widely used in electronic circuits to store energy in the form of an electrical charge.

The EKMM451VSN101MQ30S is a type of Aluminum electrolytic capacitor specifically designed for medium voltage and power applications, and is known for its high power density, small size and low ESL. Its design includes a cylindrical electrolytic portion, as well as a solid metal conductor core that is encased in the middle of the capacitor. This core provides high stability to reduce internal inductance, and its construction allows for a wide operating temperature range from -55°C to 105°C.

The EKMM451VSN101MQ30S has a capacitance of 4.5mF @ 5.5KV, a voltage rating of 5.5KV, a ripple current of 4.2A and a lifespan of 105°C. Additionally, it has an operating temperature of -55°C to +105°C, a dissipation factor of 5.2%. Its design also includes an aluminum foil anode, a sintered anode matrix, an anode lid, an anode well, and a cathode terminal.

The working principle of the EKMM451VSN101MQ30S involves the application of alternating current to the aluminum foil anode, which creates an electrical field that causes the electrolyte within the capacitor to break down. The breakdown of the electrolyte causes electrons to be attracted to the anode, creating a voltage that is able to store energy in the capacitor.

The main part of an aluminum electrolytic capacitor is the electrolyte, and its characteristics are determined by its composition and concentration. It is usually composed of either water or ethylene glycol, although other types of liquid may also be used. The electrolyte is also responsible for allowing current to flow through the capacitor, as well as for controlling the capacitance and the lifespan of the device.

The EKMM451VSN101MQ30S is commonly used in high voltage and power applications, such as in power supplies, motor controllers, LED lights, and photovoltaic devices. It is also suitable for automotive, industrial, medical, and aerospace applications, as it is designed for high reliability and long-term stability. Additionally, it provides high stability and excellent noise control in switching power supplies and audio circuits.

To sum up, the EKMM451VSN101MQ30S is an aluminum electrolytic capacitor designed for high voltage and power applications. It features a cylindrical electrolytic portion, a solid metal conductor core, and a wide operating temperature range. Its working principle involves the breakdown of electrolyte and resulting flow of electrically attracted electrons, which are then able to store energy in the capacitor. The EKMM451VSN101MQ30S is widely used in power supplies, motor controllers, LED lights, photovoltaic devices, and other applications requiring high reliability and long-term stability.
