Fixed inductors, also known as fixed coils, are resistive elements commonly used in electronic products. 74437349012, a type of fixed inductor, is widely used in various applications, ranging from telecommunications to consumer electronics. This article will discuss the field of application and working principle of 74437349012.

Application Field

74437349012 fixed inductor is suitable for use in a variety of applications, including electronic equipment, DC/DC converters, mobile phones, radios, land mobile radios, phones, computers and portable electronic devices. It is also used in high-power RF amplifiers and power supplies. In addition, 74437349012 fixed inductors can also be used in low frequency circuits and power systems, such as in audio, consumer electronics and power supplies, due to its low DC resistance and high inductance.

Working Principle

74437349012 fixed inductor works on the principles of electromagnetism, wherein the electric current passing through a wire produces a magnetic field. The fixed inductor comprises a metal core (known as the “inductor”) into which a wound wire is formed, creating a closed loop that acts as an inductor. When the electric current is applied, a magnetic field is generated and this induces an electromotive force (EMF) in the wire. The EMF in the wire is known as the back EMF; it creates a counter-EMF opposing the forward EMF and works to reduce the current flow in the circuit.

The amount of back EMF produced is determined by the inductance of the fixed inductor. The inductance of the 74437349012 can range from 20mH to 100mH, depending on the design of the inductor. The higher the inductance, the lower is the current which flows through the circuit. In addition, 74437349012 fixed inductors can also be used to filter out unwanted high and low frequency signals in the circuit.

In conclusion, 74437349012 fixed inductors are widely used in a variety of applications, ranging from telecommunications to consumer electronics. They work on the principles of electromagnetism, wherein an electric current passing through a wire produces a magnetic field that induces an electromotive force in the wire. The inductance of the inductor determines the amount of back EMF produced and the amount of current which flows through the circuit. 74437349012 fixed inductors can also be used to filter out unwanted high and low frequency signals in the circuit.
