Aluminum electrolytic capacitors consist of an anode made up of aluminum foil, a solid electrolyte of oxidized aluminum foil, and a paper dielectric and are the most frequently used capacitor type. The 187LMX400M2CE aluminum electrolytic capacitor is one of the most widely used applications due to its high performance levels and low cost. Apart from its wide use in consumer electronics, it also has specialized applications in aerospace, military, and industrial settings.

The 187LMX400M2CE is a non-polarized capacitor, which operates on voltage of 400VDC with tolerance of ±20%. It has maximum continuous operating temperature of 85℃ with a rated ripple current capability of 660mA (ref. to 25℃). It has a dielectric of aluminum electrolyte and has an ESR of 0.11Ω and a lifetime @85℃ of 2000hrs.

This capacitor is ideally used in applications that require high ripple current capability and extended life. The 187LMX400M2CE can be used in DC-Link circuits, power factor correction, micro process controls, LED lighting systems, wind turbines, medical systems, solar power control, and automotive electronic control systems as its performance levels make it suitable for these demanding applications.

The 187LMX400M2CE aluminum electrolytic capacitor works on the principle that an electrical charge is stored when an electric potential exists between two metallic electrodes separated by an electrolyte. The electrolyte acts as a dielectric, allowing a current to flow in one direction only while the charge is stored on one of the two opposing electrodes. When current is passed through the electrolyte, an electrostatic field is created. This field creates the equivalent of a parallel plate capacitor, with the potential between the electrodes equal to the applied voltage divided by the thickness of the electrolyte.

For the 187LMX400M2CE, the charge stored on the aluminum anode is transferred through the electrolyte to the cathode. The electrolyte has a high dielectric constant that helps to increase the capacitance of the capacitor. As the current passes through the electrolyte, a charge is established and the reactance of the capacitor decreases, allowing current to flow more easily. This capacitor also uses the effect of dielectric absorption, which allows the capacitor to store a charge even after the current has stopped flowing.

The 187LMX400M2CE aluminum electrolytic capacitor is a popular component for applications where reliability and high performance are required. It offers excellent performance and reliability at a low cost, making it one of the most widely used capacitors. Its wide usage in consumer electronics, aerospace, military, and industrial settings demonstrates its versatility and effectiveness.
