Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electronic components which are commonly used to store energy and enable electrical signals to pass through at a controlled rate. They are composed of two plates, one a thin aluminum foil and the other a sintered material like paper, and are filled with an electrolytically dissociated aqueous solution. Due to the nature of the aluminum foil, these capacitors are also often referred to as “electrolytic capacitors”. The aluminum electrolytic capacitor model EKMH630VSN682MR50T is a common device in these devices.

This capacitor has an operating temperature range between -55°C and 125°C. It is a non-polarized capacitor with a maximum DC working voltage of 630V and a Nominal Capacitance of 682μF. It is equipped with a pressure relief valve and a self-healing technology. It is commonly used in applications such as power supplies, motor drives and industrial control equipment.

Application Field

The EKMH630VSN682MR50T aluminum electrolytic capacitor is suitable for use in a number of different application fields including automotive, test and measurement, industrial automation, audio amplifiers, medical devices and lightings. In automotive applications, these caps are used in ignition and timing systems, electric window lift systems, and anti-lock brake systems. In industrial automation, these caps are used in switching and power supplies, as well as in motor drives and AC/DC motor drives.

In test and measurement applications, these caps are used in safety monitoring systems, oscilloscopes, impulse generators, and signal integrity analysis. Audio amplifiers require these caps for power resolution and signal processing. Medical devices use these caps for various applications including pulse generators, electrocardiographs, and x-ray systems. Lightings often use these caps for flicker free dimming.

Working Principle

An aluminum electrolytic capacitor converts chemical energy into electrical energy by using two electrodes – a thin aluminum foil and a porous material holding a conductive electrolyte. During operation, an electron leaves the aluminum foil, then passes through the electrolyte and ends up at the porous material. At the same time, a proton is transferred from the porous material to the electrolyte. These two reactions cause electric charge to accumulate on both electrodes. The device is charged when a voltage is applied between the two electrodes, and this charge is released when the voltage is lowered.

The EKMH630VSN682MR50T aluminum electrolytic capacitor is equipped with a pressure relief valve and a self healing technology, so that at higher operating voltages or excessive pressure, the device will release a gas which will not cause damage to the parts. This feature makes the device a good choice for applications that require precise control over current.

In conclusion, the EKMH630VSN682MR50T aluminum electrolytic capacitor is a common device for applications such as automotive, test and measurement, industrial automation, audio amplifiers, medical devices and lightings. It has an operating temperature range between -55°C and 125°C, and is equipped with a pressure relief valve and a self healing technology. The device is able to store and release electric charge, making it suitable for applications that require precise control of current.
