8230-56

Fixed inductors are typically components used in electronic circuits that store energy in the form of magnetic flux by having a wire wound into a coil around an iron core. The 8230-56 is an example of a fixed inductor that is capable of handling high current and is commonly seen in DC to DC buck converters, widely used in low-power applications.

The 8230-56 inductor is composed of a ferrite bobbin with an iron powder core and two thick coils of enameled copper wire perfectly wound, providing a higher inductance without taking up more space in the circuit. It has a low DC resistance for a higher-efficiency power transfer, while its high-frequency electrical properties help to reduce audio noise. This fixed inductor can also handle very high currents, up to 15A, and is often used in DC/DC buck converter designs.

For applications where more current is required, some inductors use a more resilient wind-around design to increase the current-carrying capacity, but this often requires a larger size and higher cost. The 8230-56 fixed inductor, on the other hand, is a lower cost solution to providing high current-handling capabilities in a relatively small size. The high current handling is made possible by using a thicker insulation layer inside each of the two coils of enameled copper wire, increasing the current-handling capability by up to fifteen amperes (15A).

The working principle of a fixed inductor is simple. When current passes through the coil, it creates a magnetic field which stores energy as a form of magnetic flux. This magnetic flux is then imparted as a change in the inductance of the inductor, which is generally measured as the ratio of the change in magnetic flux to the change in current. As the current continues to flow through the coil, this change in inductance will cause a voltage to be generated across the inductor, meaning that the inductance and voltage are proportional.

The purpose of the 8230-56 fixed inductor is to help filter out unwanted signals from the circuit of the DC/DC buck converter, generally at higher frequencies. The inductor acts as an impedance or “load” to higher-frequency signals (or noise) that would otherwise cause noise and distortion in the signal. By providing a high inductance in its small form factor, the 8230-56 works as an effective filter to keep signals within the circuit clean and noise-free.

In conclusion, the 8230-56 fixed inductor can provide an effective and low-cost solution enabling high current handling in applications such as DC/DC buck converters. With its two thick coils of enameled copper wire wound around an iron core and high inductance, the 8230-56 is able to filter out higher frequency noise and distortion from the circuit while providing a robust and affordable solution for current handling. It is a great choice for those looking for a simple yet effective inductor for their low-power applications.
