Fixed Inductors

ER1641-102JM application field and working principle

Fixed inductors are common electronic components used in many circuits. They are used to store energy in the form of a magnetic field, and the ER1641-102JM model specifically is ideal for switching applications and portable instruments. This article will explain the application field and working principle of this type of fixed inductor.

Application Field of ER1641-102JM

The ER1641-102JM inductor is a small, encapsulated fixed inductor with a maximum heat rating of 85°C. It is ideal for general electronics applications, such as automotive battery management, personal computers, wireless devices, and consumer electronics. As a switching inductor, it is suitable for low frequency signal conditioning in a range of automotive, portable instrumentation and telecom/data applications.

The ER1641-102JM is also suited for input and output filtering in DC-DC converters, current-mode controllers and switch-mode power supplies. Compared to other fixed inductors, the ER1641-102JM provides higher inductance at a given physical size, making it ideal for power supply designs with fixed inductance requirements.

Working Principle

Fixed inductors, including the ER1641-102JM model, follow the basic principles of electromagnetic induction. When a current passes through the inductor, it creates a magnetomotive force, which in turn causes an opposing current to oppose the main current. As the magnetic field builds up, the opposing current increases, creating a voltage drop across the inductor. This is how an inductor works.

The ER1641-102JM is a fixed inductor, meaning that the magnetic field created by the current is kept at a constant level. As such, the voltage change across the inductor is also kept at a constant level. This makes it ideal for low-frequency switching applications, as the signal is kept consistent regardless of the frequency of the input signal.

Conclusion

The ER1641-102JM fixed inductor is ideal for switching applications and portable instruments. Its unique design allows for higher inductance at a given physical size, and its ability to keep a consistent voltage drop makes it perfect for low frequency signal conditioning. For these reasons, the ER1641-102JM is an excellent choice for a variety of automotive, portable instrumentation and telecom/data applications.
