Fixed Inductors

Inductors, also known as coils, are passive components used in electronic circuits to store or control energy in the form of magnetic fields. A fixed inductor, as its name implies, is one that cannot be adjusted.The HF1008R-471K is an example of a fixed inductor. It is a type of wire-wound inductor, meaning that the inductance is determined by the length, diameter, and number of turns of a coiled copper wire. This type of inductor can also be used as an RF choke, or an inductor designed to block high-frequency signals while allowing low-frequency signals to pass.The HF1008R-471K core is made of ferrite, a type of magnetically permeable ceramic material with low electrical resistivity, meaning that it is an ideal material for use in inductors. It has an inductance of 0.47uH and can handle up to 100mA of current.The HF1008R-471K is commonly used in a wide range of applications from automotive electronics and telecommunications, to audio and computer circuits. It is particularly well-suited for use in battery charging circuits, as it can efficiently convert high-frequency AC signals into DC. It can also be used as an electromagnet, as a choke to filter EMI (electromagnetic interference) from the power supply, or as a transducer to convert mechanical motion into electrical signals.In terms of working principle, the HF1008R-471K works by creating a magnetic field when current flows through it. This magnetic field is believed to be created by a circulating current in the core of the inductor known as the ‘induced current’. This induced current creates a reaction in the coils, producing a magnetic field. This magnetic field is then used to oppose the current that produced it, creating inductance.The HF1008R-471K inductor also has an impedance frequency response that is relatively flat across a wide range of frequencies. This means that it acts as a reliable filter for signals, only allowing those at the desired frequency to pass.Overall, the HF1008R-471K is an extremely versatile and reliable component, making it an invaluable asset to many electronics designers. It is suitable for a wide variety of applications, due to its flat frequency response and high current rating, and is an ideal choice for numerous circuits.
