Fixed Inductors

Inductors are essential components for electric circuits, especially in radio-frequency (RF) circuits, allowing current to flow in directions that can vary. Fixed inductors are typically simple inductors, classified as air-core inductors, and consist of a coil of wire with one or more turns with a fixed inductance, and are widely used in electrical and electronic products, from small circuits to large power supplies. One example of such a fixed inductor is the SCMD4D12-100.The SCMD4D12-100 is an air-core, monolithic, multi-section inductor that is capable of providing both broadband attenuation and filtering of RF signals. The device is composed of four individual inductors arranged in a 12-pin through-hole package. The inductors are connected in a series configuration, which allows for the transfer of energy from one inductor to another. This arrangement also allows for a wide range of inductance values to be produced, ranging from 0.1 µH to approximately 10 µH.The device can be used to filter signals in both low-power and high-power RF applications. It also can be used for decoupling, blocking, attenuating, and other specific applications. The specific applications depend on the frequency range and the specific requirements of the design. For instance, it can be used for low-frequency applications such as HF receivers and digital communication systems.In terms of its working principle, the SCMD4D12-100 has a voltage transformer circuit embedded within it. When a voltage is applied to the device, the magnetic field generated by the inductors\' windings cause an induced current to flow in the opposite direction and through the connected circuit. This current is then used to pass energy through the circuit. By changing the number of turns in the windings, the inductance value of the device can be controlled.To summarize, the SCMD4D12-100 is a fixed inductor that provides a range of inductance values for either low-power or high-power RF applications. It consists of a voltage transformer circuit with four inductors connected in a series configuration. The device is capable of providing broadband attenuation and filtering of RF signals, as well as decoupling, blocking, attenuating, and other specific applications, depending on the design requirements.
