Aluminum electrolytic capacitors are divided into two categories: small aluminum electrolytic capacitors and aluminum electrolytic capacitor modules. The 757D188M025EK3D belongs to the former, usually referred to as "two-pin aluminum electrolytic capacitors".

Application Field of 757D188M025EK3D

Due to its reactive filtering characteristics, 757D188M025EK3D is widely used in equipment and small devices that require smooth currents, including power supplies, power amplifiers, color TVs, home appliances, cordless phones, video equipment, amplifiers, computers, etc. In addition, these components\' bulk capacitance is useful for suppressing circuit noise and harmonics, and resonance applications are of use in multiple types of circuits.

Working Principle of 757D188M025EK3D

A 757D188M025EK3D consists of two metal electrodes separated by a layer of oxide that acts as an insulating medium. The oxide layer around the cap\'s electrodes are part of the chemistry that makes up the capacitor. An electric current passes through the capacitor when one of the electrodes is connected to the charge source. This electron flow passes through the oxide layers, forming an electric field that attracts the electrons. This electric field creates a static potential difference between the two electrodes that increase as electrons accumulate on one of the electrodes. The capacitance is determined by the area of the electrodes, the distance between them, and the type of oxide layer.

Within the 757D188M025EK3D capacitor, the negative and positive electrodes are made of aluminum foil. The electrolyte is an ionic oxide of the aluminum foil. This oxide layer has a certain value of capacitance, which can store charges. Through the electro-optical effect, the oxide film of the aluminum foil has a thickening effect and prevents the opposite charges from attracting each other, which changes the characteristics of the two-pin aluminum electrolytic capacitor. This change of the capacitor\'s characteristics also occurs when the ambient temperature changes. As the capacitor ages, the oxide layer thins, leading to an increase in the leakage current and a decrease in the capacitance.

For the 757D188M025EK3D capacitor, being polarized means that the leads, or pins, of the component have polarity information stamped on them. The leads are marked with a + sign indicating the positive connection and a - sign indicating the negative connection. When the capacitor is connected to a circuit, it must be oriented in the appropriate direction.
