Fixed inductors are components in electronic circuits that accept energy from a current carrying wire coil and hold it until the current or voltage provides another. Generally, they are composed of a core, a wire coil, and a capacitor for frequency control. The 38H302C is a type of fixed inductor used in a wide range of applications.

The core of a 38H302C fixed inductor is ferrite, which is a material made from iron oxide combined with ceramics. It provides a strong and steady impedance while being highly stable in temperature. The iron in the ferrite also facilitates low inductance loss. The wire coil is wound around the ferrite core tightly to ensure that the energy is stored and released properly. A capacitor is placed near the coil to reduce the inductance due to winding resonance, further enhancing the performance of the inductor.

The 38H302C fixed inductors are designed for applications that require low DC resistance and high current capability. They are often used in switching power supplies, voltage regulators, and various other power electronics. The inductors are highly reliable and stable, with high temperature ratings and excellent noise suppression characteristics. They can also be used in a broad range of voltage ranges, which allows them to be used in many different types of electronics.

The working principle of the 38H302C fixed inductors is relatively simple. When an AC current passes through the wire coil, it creates a magnetic field that stores the energy. Whenever the magnetic field experiences a disturbance, even if it is just a change in current or voltage, the field dissipates and the energy stored inside is released. This process repeats as long as current and voltages fluctuate around the inductor, and the amount of energy released is proportional to the strength of the disturbance.

In summary, the 38H302C is a type of fixed inductor that is used in a wide variety of applications. It consists of a ferrite core, a tightly wound wire coil, and a capacitor for frequency control. The inductor is designed for high current and low DC resistance. It is highly reliable and stable, with excellent noise suppression characteristics. The working principle of the inductors is based on the principle of stored energy being released when the magnetic field experiences a disturbance.
