Fixed inductors, also known as non-variable inductors, are electrical components that store energy in the form of a magnetic field. They consist of a wire wound around a core material, often ferrite or iron. The inductor acts as a filter, smoothing out varying current spikes and filtering out high frequency components. The LQW18AN34NJ80D is a type of fixed inductor, utilizing an iron core material, for use in automotive, computing, and industrial applications. It has a highly reliable, low profile through-hole construction, and is capable of withstanding high temperatures and vibration.

Application Field

The LQW18AN34NJ80D fixed inductors is suitable for all automotive, computing, and industrial applications. The through-hole construction ensures high reliability, even in harsh environments. This type of inductor is especially useful in applications requiring stability in power supplies, and smoothing out of current spikes. It can be used in circuits for TV sets, entertainment systems, and various other types of consumer electronics, where it helps to filter out high-frequency components and keep the power supply stable.

Working Principle

The working principle of the LQW18AN34NJ80D fixed inductor is based on Faraday’s law of electromagnetic induction. When current flows through the inductor, it creates a linear magnetic field in the core material, creating a mutual inductive effect between the two. The mutual inductance creates an electromotive force (EMF) the opposite direction, in opposition to the applied current. This EMF increases with increased excitation, and is usually referred to as the back EMF or inductive kick. This kick is what helps to filter out high-frequency noise and helps to smooth out any voltage spikes.

While the exact amount of inductance is dependant on the core material, the shape of the inductor and the number of windings, the LQW18AN34NJ80D fixed inductor is rated at 0.4µH. This unit is also made with a ferrite core material which increases the operating temperature capacity and allows it to handle higher power levels.

Conclusion

The LQW18AN34NJ80D fixed inductor can be used in many applications. It works on the principle of mutual inductance, and helps to filter out high-frequency noise and smooth out voltage spikes. It has a high reliability, low profile through-hole construction, and is able to withstand high temperatures and vibration. This type of inductor is an ideal choice for automotive, computing and industrial applications where stability and protection of sensitive components are critical.
