Fixed inductors are electrical components used in a variety of electronic circuits and applications. The 0819-92F is a fixed inductor designed for use in AC power equipment, such as AC adapters, switching power supplies, and LED drivers. This inductor has an operating temperature range from -40°C to +125°C, making it suitable for extreme operating conditions. The nominal inductance of the 0819-92F is 0.82µH, with a tolerance of 10%, and a carries a maximum current rating of 105A.
This inductor features a ferrite core, which leads to the low nominal current, and helps to reduce EMI interference. The core is paired with an air gap, which provides more stability in the inductor\'s impedance, allowing it to tolerate high voltage and current spikes without disruptive ringing. This air gap also helps to reduce the inductor\'s self-resonant frequency, allowing the inductor to maintain a steady current even when the alternating current frequency fluctuates. The outer winding of the inductor is composed of tinned copper wire, which helps to reduce eddy current losses.
The 0819-92F is most commonly used for power filtering purposes. It helps to prevent the emission of harmonics, which can interfere with other electrical components or cause audible noise in audio applications. It can also be used to reduce the peak-to-peak voltage of the applied AC current, helping to ensure the safety of other connected components. In addition, the 0819-92F can be used to reduce the noise and ripple in a switching power supply.
The working principle of a fixed inductor is simple. As the current changes, the magnetic field generated by the inductor core also changes. This causes a corresponding change in the voltage across the inductor, opposing the change in current. This process, known as inductance, helps to regulate the current and prevents disruption in the connected circuit. The greater the inductance of the inductor, the more effective it is at regulating the current, and the greater the opposition of the voltage change.
Overall, the 0819-92F is a versatile fixed inductor that can be used in a variety of applications. Its ferrite core and air gap help to reduce EMI interference, ensure stable operation, and keep the inductor running safely even when dealing with high voltage and current spikes. It is most commonly used for power filtering purposes, but can also be used to reduce noise and ripple in switching power supplies.
