Fixed Inductors are electronic components constructed with a wire coil around a core material. They serve as basic inductors in many applications. The MLG0402P1N3BT000 fixed inductor is a commonly used part in power supplies, switching regulators, and other power conversion circuits. It is a small, low-profile inductor measuring 0.04 x 0.02 inches (1.0 x 0.5 mm). This part is designed for surface mounting applications.

Internal Structure

The MLG0402P1N3BT000 is constructed with an iron core or permalloy core and multiple layers of a copper wire winding around it. This winding allows the MLG0402P1N3BT000 to store a magnetic field, increase the inductance of the component, and oppose changes in the flow of current. The iron core of the MLG0402P1N3BT000 increases the inductance of the component and its magnetically saturated, allowing it to store more magnetic flux. The copper wire winding is insulated with a polyamide/polyester composite or other insulating material.

Rated Parameters

The MLG0402P1N3BT000 fixed inductor has a rated inductance of 10µH +/- 10%, a rated DC current of 100mA, a self-resonant frequency of 8.2MHz, and a maximum operating temperature of +125°C. It is rated for voltage up to 150V, and has a typical DC resistance of 600mΩ. The part is also rated for a number of environmental conditions such as humidity, pressure, and vibration. It is compliant with industry standards such as RoHS and REACH.

Application Fields

The MLG0402P1N3BT000 fixed inductor is typically used in power supplies, switching regulators, audio and video amplifiers, and other power conversion circuits. The low profile and small size make it suitable for use in low-power applications such as portable devices, cellular phones, cameras, and other small form-factor consumer electronics. The high-current and high-temperature ratings make it a good choice for higher-power applications such as industrial control systems, power amplifiers, home audio systems, automotive and telecom power supplies, and other power systems.

Working Principle

The MLG0402P1N3BT000 fixed inductor works by storing a magnetic field around its core. When an applied voltage is applied to the inductor, current flows through the winding and generates a magnetic field. The inductor opposes changes in the current, which is known as inductance. The inductance of an inductor is a measure of its ability to oppose changes in the current. The greater the inductance, the greater the opposing force on the current. This opposition to changes in current is known as inductive reactance.

The MLG0402P1N3BT000 fixed inductor is constructed with an iron core or permalloy core and multiple layers of a copper wire winding, allowing it to store a magnetic field, increase the inductance of the component, and oppose changes in the flow of current. The inductance and other rated parameters of the MLG0402P1N3BT000 listed above make it a suitable part for use in power supplies, switching regulators, audio and video amplifiers, portable devices, automotive and telecom power supplies, and other applications.
