Fixed InductorsFixed inductors, also known as chokes, coils, and filters, are passive electrical components used in electrical and electronic circuit applications. Fixed inductors are generally used to block or store certain types of electrical energy, while allowing other types of energy to flow. The 1812R-152H fixed inductor is a small, surface-mount device that offers a variety of electrical benefits for circuit applications.The 1812R-152H fixed inductor is mainly used for mobile phones and other network devices. It is capable of operating in a wide range of temperatures, from -55 to +125 degrees Celsius, which makes it suitable for diverse applications. The inductor has a high current carrying capacity as it can handle 1.2A current. It is also designed to have high noise immunity to reduce the effect of EMI on its operation.The 1812R-152H fixed inductor has a low profile and occupies a minimal amount of space. It is composed of two separate parts, namely the steel core and winding. The steel core is a ferromagnetic material that stores the magnetic energy generated by the current winding. The winding, on the other hand, is the copper conductor through which the alternating current flows. This produces a magnetic field due to the self-inductance property of the inductor. The environment surrounding the inductor also plays a role in determining the magnetic field, as changes in temperature, humidity, and pressure can affect the strength of the magnetic field.The 1812R-152H fixed inductor works based on the principle of electromagnetic induction. When the alternating AC current is applied to the winding, a changing magnetic field is generated, which induces an electromotive force (EMF) within the inductor. The EMF opposes the current, thereby limiting the flow of current through the inductor and reducing the available voltage in the circuit. This is known as inductive reactance.The inductive reactance of the 1812R-152H fixed inductor also helps in filtering out unwanted frequency components from the signal, thus offering the clean electrical signals that are required in certain circuits. For example, the inductor can be used to filter out high-frequency noise from audio signals as well as from other sensitive circuits.To sum up, the 1812R-152H fixed inductor is a small, surface-mount device that is mainly used in network and mobile phone devices. It is composed of steel core and winding, which works together to generate a changing magnetic field in order to induce an electromotive force within the inductor. This provides a wide range of benefits, including current limiting, voltage clamping, and signal filtering.
