Fixed Inductors

Fixed inductors are passive electronic components which have a fixed inductance value and are able to store energy in the form of magnetic flux. The "fixed" designation refers to the ability of the inductor to maintain a constant inductance value despite variations in current and other environmental stresses.

MHQ0402P3N2ST000

MHQ0402P3N2ST000 is a series of compact surface mount fixed inductors, manufactured in accordance with the stringent standards of ISO-9001. It features low DC resistance, low profile structure and excellent stability. The device also offers excellent features such as high heat resistance, low thermal resistance, wide temperature range and high current capacity.

Application Field

The application field of the MHQ0402P3N2ST000 series is very wide and varied. It is commonly used in high frequency switching power supplies, DC-DC converters, AC power supplies, audio amplifiers, mobile phones and other audio/visual electronic equipment. In addition, it can be used to construct filter circuits for high frequency signals, for suppression of EMI noise and other applications.

Working Principle

Inductors act as tanks that store energy in the form of a magnetic field. Voltage is applied to the inductor, which in turn builds a magnetic field. As current rises, the field builds up until the desired inductance level is reached. Once the inductance level is reached, the magnetic field collapses. The voltage across the inductor drops sharply, resulting in an inductive kick in the form of an induced voltage. This induced voltage will be the opposite of the applied voltage, which will once again build up a magnetic field, repeating the cycle.

The working principle of a fixed inductor can be explained as follows. When a voltage is applied to an inductor, the current increases linearly. This increase in current creates a magnetic field that builds up according to Faraday\'s law of induction. When the inductance reaches its maximum value, the magnetic field also reaches its maximum and stops increasing. The voltage across the inductor then drops sharply, resulting in an inductive kick.

This is called the working principle of a fixed inductor. The magnetic field created by the current builds up with an increase in the current and decreases when the inductance reaches its maximum value. The inductance of an inductor is determined by the physical features of the inductor, which are fixed in size and shape. This is why it is referred to as a "fixed inductor".
