Fixed Inductors

Fixed inductors, such as the 3094-822FS, are components that store energy in a magnetic field when electric current is flowing through them, and their working principle revolves around induction. The 3094-822FS is a ferrite core power inductor that features common mode noise suppression. It has a Self Resonant Frequency of approximately 8.2MHz and a DC Resistance of 0.3-0.6Ω. 3094-822FS inductors are used in a wide range of applications, including DC-DC applications, charging circuits, power line noise-suppression, and common-mode noise filters. In DC/DC converters, the 3094-822FS are utilized to reduce ripple, regulate the voltage and control current. Additionally, they are used in automotive and renewable energy systems. In terms of its working principle, the 3094-822FS generates a magnetic field when current is flowing through it. This magnetic field can influence the current surrounding it, producing electric induction when the circuit is completed. This induction creates opposition, which produces an effect that limits the current in the circuit. This is known as self-induction, and it is useful for controlling current. The 3094-822FS inductors are also used for radio frequency (RF) applications. Since the inductors store energy in the form of the magnetic field, they can provide equal amounts of both inductance and capacitance in parallel-resonant circuits. This enables the 3094-822FS to tune RF circuits, allowing them to filter out any unwanted gains and frequencies. When used in line-noise suppression applications, the 3094-822FS will reduce the harmonic content of the current. This can be used in AC circuits to reduce radiated emissions. It can also be used in switching power supplies and in LED driver circuits to limit noise and reduce power losses. In conclusion, the 3094-822FS is a popular power inductor thanks to its wide range of applications. It can provide current control, reduce ripple, filter RF noise, and suppress common-mode noise. As such, the 3094-822FS is a great choice for any engineer who needs a reliable power inductor.
