Fixed inductors are electronic components found in almost all electrical circuits. An inductor typically consists of a coil of wire and closely related parameters, such as inductance and Q-factor. The 1812-473F is an example of an advanced fixed inductor, used in a wide variety of applications, including power supplies, audio amplifiers, and instrument amplifiers. This article will discuss the features and working principle of this type of inductor, as well as its various application fields.
The 1812-473F is a high performance, low cost inductor with a maximum rated current of 3.0A, and a temperature range of -55°C to +125°C. It is composed of a ferrite core material, and a coil of wire wound around it. Its inductance value is 4.7μH ±10%, a typical loss factor of 0.33 at 10kHz, a saturation current of 3.0A, and a Q-factor of 40 at 10kHz, which make it suitable for many different applications.
This inductor’s working principle is based on Faraday’s Law of induction, which states that an electric current through a conductor in a magnetic field creates a electromotive force (EMF) in that conductor. In the case of the 1812-473F, the core material (ferrite) and coil form what is known as a “magnetic circuit,” where the coil itself constitutes the electromotive force. When the current passes through the coil, an electromagnetic field is created, which then creates an opposing EMF and reduces the current.
The 1812-473F inductor is used in a variety of different applications, such as in power supplies, audio amplifiers, and instrument amplifiers. In power supplies, it is used to “smooth” out the current by providing an “opposing EMF” to the current, thus reducing line interference and creating a more stable power supply. In audio amplifiers and instrument amplifiers, it is used to provide a constant level of power to the circuit, thus producing a smooth, consistent sound.
Another application is in digital circuits, where the 1812-473F helps with signal filtering. The inductor acts as a low pass filter, allowing only signals of a certain frequency or below to pass through. This type of filtering is often used to reduce noise in digital circuits, thus improving the signal-to-noise ratio.
The 1812-473F inductor is an example of a high-performance, low-cost component used in a variety of applications. Its inductance value, Q-factor, temperature range, and maximum current rating make it suitable for many different applications. Its working principle is based on Faradays Law of induction, where an electric current through a conductor in a magnetic field produces an EMF in the conductor. This EMF directly affects the current passing through it, allowing the inductor to be used for filtering and smooth power transfer in various types of electronic circuits.
