Fixed Inductors

Inductors are one of the most frequently used components in the electronic industry. Fixed inductors are coils of wire having a certain number of turns and an external magnetic field. They are used in most electronic circuits in order to store electrical energy and to suppress transients or noise. The HCMA1305-1R8-R is a type of fixed inductor commonly used in AC-DC power supplies. The HCMA1305-1R8-R is a mutual inductor with a ferrite core. The significant parameter is the inductance which is determined by the number of turns, the core size and the type of material (ferrite or iron). On the external circumference, two leads of tinned copper wire make contact with the soldering pad. This device features an extended air-gap between the core and the coil windings, which helps reduce the addition of external noise in the circuit. The working principle of an inductor is based on Faraday\'s law of induction. This states that changing the magnetic field around a coil will induce an electromotive force, or EMF, which is equal to the rate of change of the magnetic flux with respect to the coil. This EMF will generate a current in the coil. On the contrary, when a current is passed in the coil, a magnetic field will be created in and around the coil. This magnetic field will be much stronger than the one created by a passing direct current. The HCMA1305-1R8-R inductor is commonly used in switching power supplies, where the required inductance may vary from 5 microhenries to 20 millihenries. It is ideal for use in low-power, high-frequency applications, as it offers very low core losses when operated over a wide range temperature and frequency. Furthermore, it has a very good reliability due to its excellent insulation and moisture resistance. Aside from AC-DC power supplies, the HCMA1305-1R8-R inductor can also be used in different types of regular AC and DC circuits. In AC circuits, the inductor is usually used as part of an LC filter or an intermediate filter, where it can help reduce noise and stabilize output voltage in electric power systems. In DC circuits, the inductor can be used as either a choke or a filter, to smooth out ripple currents and reduce voltage drops. In conclusion, the HCMA1305-1R8-R inductor is a typical fixed inductor commonly used in power supplies. It offers low losses, high temperature and frequency stability, and excellent insulation and moisture resistance. Moreover, it can also be used in both AC and DC circuits, as either part of LC filters or as chokes and filters to smooth out ripple currents and reduce voltage drops.
