HF1008R-390J is a fixed inductor. It is a passive electronic component that forms an inductance circuit in an electric circuit. The HF1008R-390J is typically composed of a single coil of insulated copper wire, in which a magnetic field sources around and is insulated inside the coil. The resistance is about 10 Ohms, and the receiver is constructed with a 22mH inductor and a 100 mOhm internal resistance. This inductor has a 10A saturation current, which makes it a very versatile component to be used in different applications.

The HF1008R-390J can be used in a variety of ways, including radio frequency applications, linear voltage regulators, DC to DC converters, and switching voltage regulators. Its use in radio frequency applications includes antenna matching, selecting and filtering radio frequency signals, and preventing current overload in high-frequency circuits. It is also used in voltage regulators, where it is utilized as an output filter to ensure stability in the output voltage. The HF1008R-390J is also an ideal choice for DC/DC converters, as it can increase stability when multiple DC/DC converters are connected. In switching voltage regulators, HF1008R-390J can be used to reduce the ripple current when increasing or decreasing the voltage.

The working principle of HF1008R-390J lies in its magnetic field produced when current passes through the copper wire. When a current flows through the wire, a counter force named “electrical inductance” is produced, which means the wire resists the passing current. As the electrical inductance increases, the flow of current decreases, eventually stopping. Under the constant current, a magnetic field circulates within the loop and is maintained in the inductor.

The maximum DC current that can be conducted through the HF1008R-390J is 10A. At the same time, with the electric inductance of 22mH, the voltage across the inductor increases with the forward current and, at the same time, the impedance decreases. The power dissipation of the inductor is inversely proportional to the ambient temperature. Therefore, it is recommended the operating temperature for the HF1008R-390J should be limited to a maximum of 45°C.

HF1008R-390J is a great choice for various applications, such as antenna matching, RF signal filtering and switching voltage regulators. Due to its high saturation current and its good tolerance for temperature fluctuations, it is an ideal component when dealing with different kinds of electronic circuit needs. The correct application and operation of the HF1008R-390J ensures it will perform as desired and provide an excellent output.
