Fixed Inductors are essential parts in modern electronics, especially in radio frequency devices. The 4379-821HS is one such component. With its wide range of applications, it is suited for many types of circuits, from power supply to timing and filtering circuits.

The 4379-821HS is a non-polarized, ceramic-film, fixed inductor that offers values from 4.7 to 470 uH. It also has a high rated current from 15 to 100 mA respectively, helping with the continuous operation of the circuit. The 4379-821HS can withstand higher peak currents with its rated current, enabling it to operate at higher frequencies. It also has a low DC resistance of 0.05 Ohm and a low reactance of 0.05 Ohm at 1 MHz.

The applications for the 4379-821HS include antennas, attenuators, power filters, RF amplifiers, power line filters, delay and timing circuits, power distribution networks, and switching voltage regulators. It can also be used for high-precision impedance matching, low-noise signal filtering, and frequency shifts in radio communication circuits. Its low-saturation, low-inductance features make it suitable for high-frequency signal processing in switching power supplies.

The 4379-821HS works on the basic principle of electromagnetic induction. When AC power is applied to the component, a rotating magnetic field is present. This provokes an electric field inside the inductor. This electric field induces currents in the internal windings of the inductor, which are related to the resistance of the inductor. The rate of the induced current is directly proportional to the frequency of the applied AC voltage.

The 4379-821HS also offers improved thermal resistance when compared to other inductors, making it suitable for extended operation at higher frequencies. It is also designed to offer high electromagnetic noise rejection, low insertion loss, low self-resonance, and consistent inductance. This, along with its stable operation, makes it useful for applications that require high-precision and reliable inductor solutions.

The 4379-821HS is an ideal component for radio frequency devices. Its wide range of applications and stable operation make it suitable for various types of circuits. With its high current rating and low resistance, the 4379-821HS is an excellent choice for high-frequency signal processing and extended operation in switching power supplies.
