Fixed Inductors

Fixed inductors are electronic components consisting of a winding made of a conductor and a core. These components are used in various electrical circuits and devices and can be characterized by their inductance, quality factors, and max current and voltage ratings. One of the most popular fixed inductors is the PL9412NL, which has many applications and works on the basis of Faraday’s Law. This article will explain the application field and working principle of the PL9412NL fixed inductor.

Application Field

The PL9412NL fixed inductor is mainly used in power supplies, switching power supplies, DC/DC converters, EMI filters, DC/AC inverter, and PFC circuits. This type of inductor is also commonly used in computers, telecommunications, radio systems, and many other types of electronic devices. Furthermore, this inductor is cost-effective, has low parasitic inductances, and offers excellent temperature stability and power handling capabilities.

Working Principle

Fixed inductors work on the basis of Faraday’s Law, which states that the voltage induced in a closed loop of a conductor is proportional to the rate of change of the magnetic flux passing through it. This means that when an AC voltage is applied across the loop, the current flowing through the inductor is proportional to the primary current of the voltage source. The primary current produces a magnetic field that induces a secondary voltage in the inductor’s closed loop. This secondary voltage is then fed back into the circuit, and the process is repeated.

The PL9412NL fixed inductors use this principle by having a magnetic core that can produce higher magnetic flux levels than other types of inductors. This core is also made of a special material which makes the inductor have better temperature stability, allowing it to work in extreme environmental conditions without any performance drops. The PL9412NL also has a very low DC resistance so it does not suffer from significant voltage drops during operations, and its self-resonant frequency is also very high.

Conclusion

The PL9412NL fixed inductor is one of the most popular types of inductors due to its low cost, low parasitics, excellent temperature stability, and power handling capabilities. This inductor can be found in many electronic circuits and devices and works on the basis of Faraday’s Law. Its magnetic core allows it to produce higher magnetic flux levels and its low DC resistance ensures that it does not suffer from significant voltage drops. All these features make the PL9412NL fixed inductor a great choice for various applications.
