Fixed Inductors are electrical windings formed by coils of thin conductors, like copper or aluminum, wound on a ceramic, plastic, or ferrite form and then encapsulated in a variety of materials including molded plastic, baked enamel coatings, or metal cans. They are employed in a wide range of electronic and electrical circuits, often for radio frequency coils or filtering applications. In this article we will discuss one such component, the AQ1052N4S-T, and cover its application fields and working principles.

The AQ1052N4S-T is a surface-mountable fixed inductor that is inductively and resistively stable across frequency, temperature, and DC bias range. It has a low DC resistance, is highly reliable, and has a wide range of inductance values. This component is highly efficient in thermal energy management and has excellent vibration and EMI attenuation capabilities.

The AQ1052N4S-T can be employed in a variety of applications, including radio frequency (RF) frequency switching, wireless communication, antenna design, optical transceivers, power converters, audio amplifiers, and filtering. This inductor offers excellent linearity and low return loss at frequencies ranging from DC to tens of GHz, making it well-suited for high-frequency circuits.

The AQ1052N4S-T inductor has an internal ferrite core that stores energy in the form of magnetic fields. As current passes through the conductor, the ferrite core increases the inductance of the coil, resulting in an increase in the energy stored in the magnetic field. This stores the energy in the form of magnetic flux, and as the current is reduced, the magnetic field collapses and the stored energy is returned to the circuit as an induced voltage.

The AQ1052N4S-T inductor consists of a number of layers, including an insulated copper wire and an outer sheath. The wire serves as the primary conductor and carries the current to be stored in the core. The sheath, usually made of a thin ferromagnetic material, acts as a shield and helps reduce electromagnetic interference (EMI).

The AQ1052N4S-T has a wide range of features designed to improve its performance. Its low-frequency operation is enhanced by its extremely low DC resistance, which helps reduce losses as current passes through the inductor. In high-frequency operation, the component utilizes a small air gap between the wire and core to reduce losses associated with hysteresis. The component also features an enhanced vibration dampening capability, excellent linearity, and excellent EMI attenuation capabilities.

In conclusion, the AQ1052N4S-T is a highly versatile fixed inductor suitable for a variety of applications across different industries. Its features such as enhanced linearity, low resistance, and EMI attenuation ensure that the component can be used in a wide range of applications, from RF communication to audio amplification and power conversion.
