Fixed Inductors

Fixed inductors are electric components which convert electrical energy into magnetic energy, allowing for their transfer to other components or for storage. The MHQ1005P3N5ST000 is a small, pin-mounted inductor which makes use of a 0402 sized package and offers high saturation current along with a low DC resistance. This makes it suitable for use in many applications where higher frequency is involved.

Application Fields

The MHQ1005P3N5ST000 is mostly used in DC-DC converters, switching regulators, filter circuits, and charge pumps in automotive, communication, and consumer electronics. The high saturation current makes it suitable for regulating power supply and voltage conversion.

Working Principle

The MHQ1005P3N5ST000 inductor works by storing energy in a magnetic field as current passes through it. This process requires a closed loop of wire which, when energized, magnetizes the core and builds up a magnetic field. This magnetic field is made up of two parts: static, which occurs when the coil is completely closed, and inductive, when the coil is part of a loop.

When a voltage is applied to the inductor, the magnetic field increases, and as the current passes through the coil and the area around it, energy is created. This energy can be stored, or transferred to another component through capacitance or resistance. The inductance of an inductor is important, as it determines how much energy is stored in the magnetic field.

The value of an inductor can be calculated using the equation E=-L(di/dt), where: E represents the voltage, L represents the inductance, and di/dt represents the rate of change of the magnetic field.

Conclusion

The MHQ1005P3N5ST000 is a small, pin-mounted inductor which offers high saturation current and low DC resistance. It is most commonly used in DC-DC converters, switching regulators, filter circuits, and charge pumps in automotive, communication, and consumer electronics. The inductor works by storing energy in a magnetic field when current passes through it, with the voltage and inductance being key for its performance.
