LQR2W123MSEJ

Aluminum Electrolytic Capacitors are widely used for applications involving filtering, decoupling, energy storage, timing, and many other purposes. The specific application that the LQR2W123MSEJ device is rated for is the filtering of pulses with high-frequency class H 220VAC and 240VAC power supply. The device is also suitable for other purposes with similar requirements for pulse filtering.

The device works on the basis of applying an electric voltage between two electrodes across the capacitor. They use a thin anodized aluminum oxide film as a dielectric to store the electrical energy in the form of an electric field between two conducting plates. When the voltage across the capacitor is above the rated value, the capacitor will become charged and store the energy in the form of an electrical field in the dielectric layer.

The capacitance of an electrolytic capacitor is generally determined by its physical size and the aluminum oxide dielectric thickness. The device is generally polarized, as the aluminum oxide dielectric layer is normally made up of a positive and negative electrode. This polarization gives the device the ability to hold a voltage indefinitely, but also adds some restrictions to its use. The device cannot be connected in reverse without experiencing permanent damage.

The LQR2W123MSEJ device is rated as a 75µF, 220VAC, 240VAC Class H, bipolar filter capacitor. This device has a capacitance of 75µF, which is a relatively large value as compared to some other types of capacitors. It has a terminal voltage rating of 400V and a maximum ripple current of 1.8A. The device is also designed to operate under a wide temperature range of -25°C to +105°C.

The applicable application fields for the LQR2W123MSEJ device are mainly AC and pulsed DC motor drives, AC/DC converters, AC/DC power supplies, AC motor protection, DC- link filters, and others . It is suitable for use in applications that require a large capacitance and a high ripple current rating.

In summary, the LQR2W123MSEJ is an aluminum electrolytic capacitor with a large capacitance and a high ripple current rating. It is suitable for AC and pulsed DC applications, such as motor drives, AC/DC converters, and AC motor protection. It is a specialized capacitor with a polarized design requiring special care when connecting to the circuit and should not be connected in reverse.
