Fixed Inductors Inductors are a type of electronic component that stores energy in the form of magnetic fields and, as the name suggests, help in the creation of inductive circuits. The key component of an inductor is it’s wire windings which provide the inductance value when working with an AC signal. Fixed inductors are types of inductors that come pre-manufactured with a predetermined value for inductance that does not change under varying conditions. One example of a fixed inductor is the SD3814-R47-R.The SD3814-R47-R is a general-purpose fixed-value inductor with a wide range of applications. It has a rated inductance of 47µH with a tolerable range of +/- 10% and a DC current rating of up to 13A, making it a versatile component that’s suitable for most applications. With a low resistance of only 0.14Ω, the SD3814-R47-R inductor is perfect for controlling the current ripple in automatic voltage switching and inverters as well as in other audio and DC/DC converters.The SD3814-R47-R has a plastic housing that is composed of thermoplastic materials and plasticizers. This gives it excellent mechanical strength and a wide working temperature range from -40°C to +155°C. The inductor also has a longterm storage temperature range of -55°C to +125°C.The working principle of the SD3814-R47-R is fairly straightforward. When an AC current passes through the inductor’s wire windings, it creates a magnetic field. This field is able to resist changes in the current, thus preventing spikes and surges in the current that can be dangerous to circuits. The larger the inductance value, the more current it is able to withstand without significant degradation.The SD3814-R47-R is a highly versatile inductor that can be used in a wide range of applications, from audio and DC/DC converters to inverters and automatic voltage switching. It has a rated inductance of 47µH, a tolerable range of +/- 10%, and a DC current rating of up to 13A. Furthermore, its plastic housing is composed of thermoplastic materials and plasticizers for excellent mechanical strength and wide working temperature range. These features make it a great choice for any application where a fixed-value inductor is involved.
