Fixed Inductors Inductors are passive electrical components with the primary function of storing energy in a magnetic field as current passes through them. Fixed Inductors are an important subset of inductors that offer predictable characteristics for design engineers. The RCR875DNP-821K is an excellent example of a fixed inductor, and understanding its application field and working principles will help to further illustrate the uses of fixed inductors.The RCR875DNP-821K is a surface mount, non-shielded inductor that has a maximum rated inductance of 8.2 microhenries.The inductor is designed to operate under an average maximum current of 750 mA and a standing temperature of +125 degrees Celsius. It is used primarily in DC-DC conversion of low voltage applications, such as DC flyback converters used in a variety of telecommunications applications such as RF transceiver systems.The inductor works on the principle of supplying a steady and reliable current to whatever electrical circuit it is connected to. A significant feature of this inductor is its ability to reject common mode noise, which reduces EMI significantly in the low voltage DC applications. The inductor can also act as a filter or signal choke in that it can reduce or re-direct dynamic currents in a given system, depending on how it is connected.The inductor is available in a variety of sizes and values to suit nearly any application. The RCR875DNP-821K is ideal for applications that require a non-shielded inductor with a low DCR and high inductance at higher frequencies. The inductor has a low resistive power core construction, with a single layer stack of windings, which reduces its susceptibility to temperature variation.The RCR875DNP-821K is an example of how a fixed inductor can improve the reliability and performance of sophisticated power applications such as mobile phones. Its inner magnetic fields are designed in such a way as to minimize external interference, and its inductance and current ratings increase its capability for thermal analysis and current filtering. Its ease of installation and small form factor reduce space and weight requirements, while its low impact on the electromagnetic environment makes it an efficient and cost-effective option for many applications.In summary, the RCR875DNP-821K is an excellent example of fixed inductors and their importance in power electronics. Its inherent magnetic and electrical properties make it an ideal choice for a number of different applications that require reliable, low noise, robust supply. And its low cost and size make it a popular and efficient choice for designers seeking to optimize their designs. The RCR875DNP-821K exemplifies the impact that fixed inductors can have, and the range of applications that can benefit from their inclusion.
