Fixed Inductors have been used in different applications and are found in electronic devices and circuits worldwide thanks to their impedance properties and ability to store energy in a magnetic field. They are a key component in the design of most electrical and electronic applications.The Fixed inductor usually consists of a coil wrapped around a core which includes a ferromagnetic material. When an electric current passes through the coil, a magnetic field is created in the core. This magnetic field stores energy and prevents changes in the applied current from propagating throughout the device. The impedance of the inductor at any given frequency is determined by the core material, the number of turns of the coil and the current passing through the coil.The SD7030-3R3-R is a example of a Fixed Inductor manufactured by Sanwa Electronics and is suitable for a wide range of applications. The SD7030-3R3-R offers high impedance characteristics across a broad frequency range of 0.1 to 400MHz making it suitable for a wide variety of circuits, from low frequency analog circuits to high frequency RF circuits. It has a high operating temperature of 105 degrees Celsius allowing it to withstand high temperatures, making it suited for power electronics applications.The inductance of the SD7030-3R3-R is 3.3uH ±30%. This can be calculated from the number of turns of the wire, the diameter of the wire and the core materials used. Generally, the more turns of wire used, the higher the inductance. The core material used affects the operating frequency range of the inductor, as ferrite cores are less prone to losses than air cores between 0 and 20MHz.The working principle of the SD7030-3R3-R is based on the Faraday\'s law which states that "a changing magnetic field creates an electric field". This means that when a changing electric current passes through the coil of the inductor, the magnetic field generated will create a voltage across the inductor, opposing the change in current. This is known as inductance.The SD7030-3R3-R is a high quality, reliable inductor that is suitable for a wide range of applications. It is especially suitable for use in RF and power circuits where its temperature stability and low inductance variation over wide frequency ranges make it particularly suited for use. Additionally, it is a cost effective solution as it comes in a compact size, making it an ideal choice for a variety of circuits.
