Fixed Inductors

Fixed inductors are electrical components that allow for the flow of an electric current in one direction around a widely looped wire, thus producing a uniform magnetic field when the current is present. 4501R-118M conducts the current in a specific coil pattern and is suitable for use in low-power applications. This article highlights the application field and working principle of the 4501R-118M. Application FieldFixed inductors are commonly used in filters, clocks, telecommunications, sensor systems, among others. The 4501R-118M is a high-precision electronic component suitable for use in both commercial and industrial applications. It is designed for use in low-power applications such as in battery-powered designs. It is also an excellent choice for land mobile radio receivers, TV signal strength detectors, handheld audio devices, and small-scale home entertainment systems.Working PrincipleA fixed inductor is a coil made of wire and a core made of a ferromagnetic material. The ferromagnetic material acts as a magnet when electrically charged. As current flows through the windings of the inductor’s coil, the ferromagnetic material creates a uniform magnetic field around the coil. This field expands and contracts as the current changes. This change in the magnetic field results in the generation of an electromagnetic force that opposes the changes in current. This electromagnetic force is what is known as self-inductance. The self-inductance generated by the coil is proportional to the product of its inductance and the current it carries.The 4501R-118M fixed inductor resembles the classic Siemens core shape but with higher precision windings and better temperature and power characteristics. The4501R-118M is designed to meet the requirements of industry-leading performance. It operates on frequencies ranging from 10kHz to 30MHz. It has a rated inductance of 0.1µH to 220µH, a rated current of 0.200mA to 3.200A, and a coefficient of solar heating of 0.003/W/°C.ConclusionThe 4501R-118M fixed inductor is a high-precision electronic component that is suitable for use in low-power conditions. Its unique design, offering precision frequency ranging from 10SkHz to 30MHz, allows for a broad range of applications including the use in filters, clocks, and telecommunication systems. Additionally, it has a rated inductance of 0.1µH to 220µH, a rated current of 0.200mA to 3.200A, and a coefficient of solar heating of 0.003/W/°C. The 4501R-118M offers excellent performance and reliability for any application.
