Fixed Inductors are a type of electronic componentused in the manufacture of integrated circuits. They are typically composed of a coil of wire, typically copper or aluminum, wound around a conducting core or ferrite core. Fixed Inductors can take many forms, such as axial, radial, or shielded inductors. The most common construction is an axial leaded part in which the coil is wound around a core and two leads are provided for mounting. The SDE06O4A-2R7M is an axial leaded part from Vishay, one of the leading suppliers of electronic components. It is an industry-standard size, with dimensions of 4 mm x 6 mm x 3.5 mm (length, width and height respectively). It has a maximum operating temperature of 125°C and it is rated for a maximum load current of 2 A. It is composed of a ferrite core, which is wound with a copper coil and covered with an acrylic coating.The SDE0604A-2R7M is most commonly used in power electronics applications as a choke for filtering applications - for example in DC to DC converters and switching power supplies. This type of application requires inductors with high maximum current ratings and relatively low DCR (with lower DCR ensuring greater efficiency at high frequencies). The SDE0604A-2R7M has a DCR of 0.58 Ω, which is relatively low compared to other choking solutions. This makes it ideal for power electronics applications.The working principle of the SDE0604A-2R7M is the same as any other fixed inductor. When a current is passed through the inductor, a magnetic field is generated in the core. This field opposes any changes in the current, producing a voltage with a frequency inversely proportional to the frequency of the current. This is known as inductive reactance, and it is the main reason an inductor is used.In the case of the SDE0604A-2R7M, the inductance value is measured at 1.4 µH, which means that when 1 A of current passes through the inductor, the voltage drop is approximately 1.4 mV at 100 kHz. This is relatively low compared to other inductors, making it suitable for high-frequency applications.The SDE0604A-2R7M is a versatile inductor, suitable for a range of high-frequency filtering and choke applications in power electronics. It is an industry-standard 4 mm x 6 mm size, with a maximum operating temperature of 125°C and a relatively low DCR. The inductance value of 1.4 µH ensures that it can cope with high frequencies, making it an ideal choice for a range of power electronics applications.
