Fixed Inductors
    
Fixed inductors are devices with a fixed inductance, usually used to store energy in a current flow. This type of device is closely related to magnetic devices, particularly transformers, windings and other coil-type electronic components.
     
The 9250-183 application field and working principle are centered around the same core circuit operation as its related magnetic devices. The 9250-183 is made of two oppositely wound coils that are connected in series with an insulated magnetic core and a metal shield. The coil is energized with a DC current, which turns the circumferential linked field of the core into a hopping field; thereby transferring energy into the electromagnetic field of the coil.
    
The basic working principle of the 9250-183 fixed inductor is based on the magnetic field generated when current passes through a conductor. When there is a current moving through the conductor, a magnetic field is produced. This created electromagnetic field will inductively alternate the direction of the current. This alternating current is the electrical charge that is stored inside the 9250-183.
    
When the capacitance of the inductor is reached, the energy will flow back into the electrical circuit in a reactive manner. This flow will then cause the induced current to flow in the opposite direction, thus creating an inductive magnetic field in the opposite polarity. This alternating electromagnetic field has the capability to induce an alternating current in an inductor or other device connected to the load.
    
At power supply frequencies, the 9250-183 may be required to handle much higher voltages and currents in order to achieve the required inductance which will depend on the powersupply circuitry of the system. This type of power inductor is therefore usually employed in Pulse Width Resistance, Resonant and High Voltage Rectifier applications.
    
Finally, the 9250-183 inductor is also used to aid in filtering out any unwanted radio frequency interference. The electromagnetic field created by the inductor can help to block or absorb the radio signals. This is why these inductors are commonly used in radio receiver circuits, as well as in other applications where radio frequency immunity is required.
