Fixed Inductors - 4470R-49F Applications and Working Principle

Fixed inductors are a type of passive electronic component capable of storing electrical energy, typically in the form of a coil of copper wire wrapped around a core of ferrite, ceramics, ferromagnetic, or powdered iron. One of the most popular models of fixed inductor is the 4470R-49F, which is a medium size radial-lead fixed inductor designed for a wide range of applications across all types of electrical and electronic circuits.The 4470R-49F fixed inductor is a general-purpose inductor designed for use in high-frequency switching and voltage regulation circuits. This inductor is ideal for a number of applications, including radio frequency (RF) signal conditioning, switching regulator feedback circuits, switching power supplies, and voltage regulation circuits. The 4470R-49F has a high inductance range and is rated for up to 15 Amps operating current . Additionally, this inductor offers excellent temperature stability and reliability.

Working Principles of 4470R-49F Fixed Inductor

The working principle of the 4470R-49F fixed inductor is based on Faraday’s law of induction. This law of induction states that an electric current produces a varying magnetic field around itself, and that a current can be induced in a nearby conductor in the presence of that varying magnetic field.When a current flows through the 4470R-49F inductor, a magnetic field is generated which then induces a voltage in the coil. This induced voltage opposes the applied voltage, resulting in a decrease in current. The amplitude of this induced voltage is proportional to the rate of change of the current, as stipulated by Faraday’s law. This enables the inductor to act as a low-pass filter, allowing only low frequencies to pass through while blocking higher frequency signals.

Applications of 4470R-49F Fixed Inductors

The 4470R-49F inductor is suitable for a wide range of applications. It can be used in power supplies, audio amplifiers, power amplifiers, voltage regulators, and motor control circuits. Its high voltage rating and stable temperature characteristics make it an ideal component for high-frequency switching and voltage regulation. In addition, the 4470R-49F inductor can also be used for RF signal conditioning and antenna matching, as it is capable of providing excellent signal attenuation for high-frequency signals. It is also well suited for noise suppression in power lines, as the inductor\'s magnetic field can help block unwanted noise.The 4470R-49F fixed inductor is an invaluable component for a variety of circuit and power supply applications requiring a compact and reliable inductor. With its wide range of operation and its robust construction, this inductor is sure to provide reliable performance for a long time.
