Fixed Inductors are electrical components which convert electrical energy into magnetic energy, and vice versa. They are used in a wide variety of electronic applications, ranging from audio systems to motor controllers. In particular, RCR875DNP-681K fixed inductors are designed for use in high-power applications, such as switching power supplies and DC/DC converters.The RCR875DNP-681K fixed inductor is a non-polarized type, meaning that it can be used in either AC or DC circuits, making it a particularly versatile device. The inductor is constructed from a ferrite core material, with two permanent magnets on either side for increased efficiency. The ferrite core material is chosen for its excellent magnetic characteristics, which provide a higher inductance value for less current than other inductor types.The RCR875DNP-681K has a rated current of 8.5A, allowing it to handle high levels of current without becoming damaged or overheating. It is also capable of operating at temperatures up to 40° C without affecting its performance. The device also has a nominal inductance of 681mH and a DC resistance of 0.019 ohms, allowing it to handle large amounts of power without excessive losses. The package size is 12.5 mm x 9.5 mm x 6.5 mm, making it ideal for applications in which size and weight are a concern.The RCR875DNP-681K is utilized in various types of switching power supplies, where it helps to regulate input and output voltages. As it is a fixed inductor, its magnetic field does not vary even with changes in frequency, which allows for more precise control of power output. It is also used in DC/DC converters where it helps to convert DC power to an AC power signal and back again.The working principle of the RCR875DNP-681K is quite simple. When a current is applied to the inductor, it creates a magnetic field which, in turn, induces an electromotive force that resists any changes in the current. This means that if the current is increased, the induced electromotive force will be increased as well, creating a counter-force that opposes the increase in current, stabilizing it. The same principle applies to AC circuits, where the inductor smooths out the current wave by creating currents that are in phase with the varying voltage.In summary, RCR875DNP-681K fixed inductors are designed for high-power applications and feature a ferrite core material, permanent magnets, and excellent magnetic characteristics. They are used in switching power supplies, DC/DC converters, and other types of applications, where they help to regulate input and output voltages and to convert DC power to an AC power signal. The working principle of the inductor is based on the induction of an electromotive force which resists changes in the current, stabilizing it.
