Fixed Inductors

Inductors are passive components that store energy in the form of a magnetic field.They are widely used in power supply and telecommunication applications as filters,stabilizers and transmission line chokes. They are used in series with capacitorsto block high-frequency signals, and in shunt with resistors to allow low-frequencysignals to pass through to the load. Fixed inductors are available in a variety of shapes and sizes,depending on the application.The RCR664DNP-391K fixed inductor is a small, surface-mount device used primarilyin power supply applications. It is made from a ferrite core material that has aninductance value of 391nH when used with a DC current of 0.7mA and at a frequencyof 100kHz. This device is particularly suited for use in applications requiring lowripple, low ESR (equivalent series resistance), and high DC current capacity.The working principle of a fixed inductor is based on the inductive properties of amagnetic field. When a current is applied through the coil, a magnetic field is createdaround it. This induces an opposing voltage in the coil, causing energy to be stored inthe form of magnetic field. When the current is removed, the magnetic field slowlydecays, releasing the stored energy.In addition to the RCR664DNP-391K, there are also a wide variety of other fixed inductorsavailable for different applications. Depending on the application, these includefixed air core inductors, power film inductors, shielded and unshielded inductors,and ferrite core inductors. Depending on the application, various types of inductorswill have different pros and cons. For example, air core inductors provide very lowinterference, while ferrite core inductors are more efficient and can handle highercurrents.Fixed inductors have a wide range of applications. They are often used in powersupplies and telecommunications, as well as consumer electronics. In power supplies,they are used to reduce ripple and provide a steady current to the load. Intelecommunications, they are used as filters and cable chokes to reduce interferenceand eliminate interference. In consumer electronics, they are used in amplifiers, FMradio antennas, and television sets.The RCR664DNP-391K fixed inductor is an ideal choice for a variety of applicationsrequiring a compact, low-cost solution. Its small size allows it to fit in tight spaces,while its low cost makes it an affordable choice for many applications. Its highcurrent capacity and low ESR make it an ideal choice for applications that requirelow ripple and high efficiency.
