Fixed Inductors

Fixed inductors or chokes are passive electromagnetic components used to store energy in the form of magnetic flux. They are typically made from a core of ferromagnetic material surrounded by a conductor, or a coil of wire, that converts electrical energy to magnetic energy. These components can be found in a wide variety of applications including radio communication systems, medical equipment, and filtering circuits.The UP4T-1R0-R fixed inductor is one such component. It is designed for high-frequency, low-power applications, such as radio receivers, FM transmitters, and portable device antenna networks. It is a miniature fixed inductor that offers low insertion loss and excellent power handling, and it is also compatible with standard through-hole mounting.The UP4T-1R0-R fixed inductor is designed with a winding made of high-temperature resin-dipped, dipped enamelled copper wire. The winding is then sealed in a monolithic metal container, allowing the inductor to better maintain its inductance across high-frequency applications. The inductor also features an electrochemical etching process on the winding wire, allowing the device to reach a higher performance level and maintain stable functioning across a wide temperature range. Furthermore, the UP4T-1R0-R fixed inductor also possesses high insulation resistance for RF shielding.The working principle of a fixed inductor is based on Faraday\'s Law of Induction, which states that a changing current will induce an electromotive force (EMF) in the coil. This can be seen in a basic inductor circuit when a DC voltage source is applied across the coil through a switch. When the switch is closed, a current flows through the coil. This current generates a magnetic field focused in the core of the inductor. This magnetic field then induces an electric field in the surrounding conductor (the winding), which then generates a voltage in the conductor that opposes the current that created it. This opposing voltage is known as an inductor\'s self-inductance, and it reduces the rate of change of current in the circuit, known as impedance, creating the inductor\'s ability to store energy.The UP4T-1R0-R fixed inductor is ideal for high-frequency low-power applications (such as radio receivers, FM transmitters, and portable device antenna networks), due to its low insertion loss and excellent power handling. Furthermore, its winding is sealed in a monolithic metal container, which allows the inductor to better maintain its inductance across high-frequency applications. This, coupled with its electrochemical etching process and high insulation resistance, make it the ideal choice for applications that require stable performance across a wide temperature range.
