Fixed Inductors refer to the inductor category with a fixed inductance value. The inductance value is fixed no matter how the operating frequency is changed, so the fixed inductors are used in the filter circuit and oscillation circuit for tuning certain frequency. In this article, we will discuss the application field and working principle of ER1537-08KM, a type of inductor.

ER1537-08KM is a type of ferrite core, fixed inductor with a diameter of 10.5mm and a height of 15mm. It is a power inductor and can handle up to an overload of 10A. It is composed of enameled copper wire, ferrite core and heat resistant resin which gives it good wear resistance and heat dissipation. It has a wide range of uses due to its insulating and protective properties.

In power circuits, fixed inductors of ER1537-08KM type are used for filtering out noise and reducing the ripple voltage of the power supply. It is especially important in applications such as radio frequencies, where voltage and frequency levels must be kept stable. They are also used in switching power supplies, laptops and other electronic equipment, where the voltage has to be accurately regulated.

As for the working principle of ER1537-08KM, it is based on the law of induction. When a current passes through the inductor, it will create an electromotive force (EMF) by the current flowing through the coil and the magnetic field created by the inductor. The EMF will oppose the change of current flowing through the inductor. This counter-EMF will limit the increase and decrease of the current, which is the electrical inductance that characterizes the fixed inductor. This is useful to limit the maximum current and to maintain a stable current.

Moreover, the fixed inductor also provides protection from over-voltage spikes. When the voltage exceeds the rated value, the inductor will absorb the spike and protect sensitive components from damage. This makes it a very popular choice when dealing with high power applications. Some designs also include a diode for additional protection.

In conclusion, ER1537-08KM is a type of ferrite core, fixed inductor with excellent performance in both filtering noise and protecting from over-voltage spikes. It has a wide range of uses such as switching power supplies, laptops and other electronics that requires accurate voltage and frequency regulation. Its working principle is based on the law of induction, creating an electric current that opposes the rise and fall of the current, which is the inductance of the fixed inductor. With its outstanding performance and reliability, ER1537-08KM is one of the most widely used fixed inductors in electronic equipment.
