Aluminum Electrolytic Capacitors are a type of capacitor that uses aluminum foil as part of the dielectric material. Such capacitors are used to store electrical energy and act as an energy buffer in a range of electrical applications from consumer electronics to industrial and automotive applications.

The 187LMX400MWBE is an Aluminum Electrolytic Capacitor which is suitable for high temperature and high voltage applications, which require high ripple current, high capacitance and long life. The dielectric material is a combination of aluminum foil and an electrolytic-grade oil, which makes it extremely reliable and durable.

The 187LMX400MWBE aluminum electrolytic capacitor has a voltage rating of 400V and a capacitance value of 187uF. It has a rer frequency of 155kHz, a ripple current of 5.2A and an operating temperature of 105°C. Its overall size is 22mm (0.86") in diameter and 75mm (2.95") in height, and it has radial leads. It is RoHS compliant and UL certified.

The 187LMX400MWBE is a polarized capacitor and must be connected with the correct polarity to properly operate. The positive terminal (usually the longer one) should be connected to the power supply and the negative terminal should be connected to ground. Reversing the polarity may result in the destruction of the capacitor.

The 187LMX400MWBE aluminum electrolytic capacitor is typically used in power factor correction circuits, audio filters, and power rectifiers to filter out AC components and reduce EMI. It can also be used in resonant circuit and high frequency power supplies. This capacitor is also used in applications where high frequency operation is needed. Some of these applications are in automotive, medical, LED lighting, computers, and consumer electronics.

The working principle of the 187LMX400MWBE aluminum electrolytic capacitor is based on the law of electrostatics which states that when an electric field is applied across two conductive surfaces, an electrical charge is induced on each one. The underlying principle is that when a voltage is applied across a capacitor, an electric field is developed which causes electric charges to be induced in the dielectric material between the plates. The capacitor stores the energy as a potential difference between the two plates, and releases it when the potential difference is reduced.

In summary, the 187LMX400MWBE aluminum electrolytic capacitor is a type of capacitor used in a range of electrical applications. It is polarized and must be connected with the correct polarity to properly operate. It has a voltage rating of 400V and a capable frequency of 155kHz. It is widely used in power factor correction circuits, audio filters, power rectifiers, and resonant circuits, among other applications. Its working principle is based on the law of electrostatics which states that when an electric field is applied across two conductive surfaces, an electrical charge is induced on each one.
