Fixed Inductors Fixed inductors are widely used in electronic circuits as part of power supplies, to filter signals, and as transducer elements. The 103-331FS is one type of fixed inductor that has a wide application field and working principle.The 103-331FS is a fixed inductor with a high current rating and is composed of a ferrite core wound with copper wire. Ferrite is a magnetic material traditionally used in transformer cores due to its strong magnetic permeability. The copper wire around the ferrite core acts as the inductor. The resulting device operates much like a transformer as well, allowing current to pass through the windings and inducing a magnetic field in the core, which is proportional to the current through the winding. The103-331FS is a fixed inductor, because a heat-resistant epoxy material encapsulates the ferrite core and prevents it from subsequent changes in shape. The use of an epoxy ensures reliable operation over a wide temperature range and long-term life. In contrast, adjustable inductors, such as the Pi Filter, may need to be changed or adjusted for different applications. The 103-331FS allows for a set inductance value depending on the windings and can endure high currents, allowing it to be used in more power-intensive applications. The 103-331FSis designed for high current applications such as motor drives and power supplies, and offers a wide range of applications due to its relatively high inductance value. It can be used for EMI suppression, voltage and current regulation, and transient suppression in power supplies. It can also be used as a DC-link inductor for motor control applications, to provide peak current support and to filter out any noise generated as a result of the rapid switching of components. Furthermore, this fixed inductor is designed to reduce temperature rise and improve system reliability when used in high current applications.The 103-331FS can also be used as a transducer element in Audio Frequency (AF) circuits, such as filters and oscillators, to couple signals from one circuit to another. This is possible due to its low losses and large inductance values, allowing it to maintain a small physical footprint while providing a large inductance value. This can also make it a great choice for a wide variety of other applications, such as wavefront shaping, automatic gain control, and magnetic recording.The 103-331FS has a wide range of potential applications and a clear working principle. Its core is made of ferrite and wound copper wire, and the epoxy encapsulation allows the inductor to function reliably at high temperatures and with high currents. Its high current rating makes it suitable for motor drives and power supplies, while its low losses and large inductance values make it suitable for use as a transducer element and for other applications.
