Fixed inductors, as the name suggests, are electrical components used to store electrical energy in the form of a magnetic field. Generally speaking, fixed inductors consist of a coil of wire wound around a core material, such as a ferrite or iron core, with two terminals connecting the coil to an external circuit. An alternating current (AC) signal is typically applied to the terminals of the inductor, resulting in the flow of a steadily changing, or "induced," magnetic field within the core of the inductor. The RL262-101J-RC fixed inductor is a high current axial leaded part with a printed circuit board (PCB) mounting feature. The product has a rated current of 2.2 A and incorporates ferrite cores, copper wire, and silicone rubber for insulation protection. Its industry rated temperature is -40 to +125 degrees Celsius and it has a rated frequency of 100 KHz.

The main application of the RL262-101J-RC is to filter and shield electrical signals to reduce their frequency and maintain a steady output voltage. Specifically, the inductor\'s role is to help eliminate voltage overshoot or ringing that is inherent in switching power supplies and other switching applications. It achieves this by acting as a buffer between the input and output of a circuit, allowing only a specific range of energy or frequency to traverse and block any other signals outside of this range. In addition, inductors act as a choke, restricting the increase in current when the supply voltage is changed.

The basic operating principle of fixed inductors is based on Faraday\'s Law, which states that the induced electromotive force (or voltage) in a coil of wire is proportional to the rate of change of the magnetic flux within the coil. In other words, when a changing current is applied to the inductor terminals, a magnetic field is generated within its core, which in turn induces a voltage across the inductor. The magnitude of the induced voltage depends on the rate of current change, as well as the inductance of the inductor. The more the current is changed, the larger the magnetic field generated in the core, and the larger the voltage induced across the inductor\'s terminals. Generally speaking, higher current applications require higher inductance values, meaning that the inductors must have a larger core to accommodate the greater number of windings.

In applications where a large number of electromagnetic interference (EMI) or power supply noise is present, as is often the case in high speed circuits, inductors can be used as a filter to prevent the noise from contaminating the signal. Here, the inductor\'s coil acts as a lowpas filter, allowing only the desired signal to pass through and blocking any noise or interference. Additionally, inductors can be used in series with a capacitor for a variety of applications such as power conditioning, noise reduction, and power supply ripple current reduction.

The RL262-101J-RC is often used in high current switching power supply and DC-DC converter applications, particularly those with low inductance values. Its PCB mounting feature makes it an ideal choice for tight-fitting or high-density applications, such as those found in computers, communications and consumer electronics. Additionally, the unit\'s axial leaded design makes it well suited for use on wave soldering manufacturing lines.

In summary, RL262-101J-RC fixed inductors are widely used in high current applications, such as switching power supplies, DC-DC converters, and noise filters, for both signal blocking and power conditioning. The inductor is optimized for low inductance values, making it an ideal choice for high density applications with limited space. Additionally, the unit\'s PCB mounting and axial leaded design promote its usability in many manufacturing processes.
