Fixed Inductors

Fixed inductors are an important part of many circuits. The ER1025-94JR is a common type of fixed inductor used in many types of electrical and electronic applications. In this article, we will discuss the ER1025-94JR\'s application field and its working principle.

Application Field

ER1025-94JR is a high-power, horizontal-type inductor, and has a wide range of applications in SMD components. It is suitable for DC/DC converters, high-frequency step-up and step-down voltage converters, and higher-frequency switching power supply units. Also, it is widely used in the fields of motor drives and power control systems. Especially, ER1025-94JR is excellent in power supply systems with high noise resistance performance.

Working Principle

The working principle of ER1025-94JR is based on the Faraday induction principle. When a current flows through a conductor such as a coil, a changing magnetic field is created around it, which induces an electromotive force (EMF). This is called mutual inductance. The ER1025-94JR\'s coil is made of fine metal wire, which increases the inductance. This increased inductance is beneficial for reducing the current ripple in high-frequency power supply applications.

In addition, the ESR and other circuit parameters of the ER1025-94JR can be adjusted according to the design requirements. By changing the core structure, material, winding method, etc., the inductance of the inductor can be increased or decreased, and its current capability can also be changed.

Advantages

The main advantages of using ER1025-94JR in electronic equipment include its high current capacity, large rated power, low internal resistance, small size, and light weight. It also has high insulation resistance and a wide temperature range. In addition, ER1025-94JR inductors are designed with a proven structure that is resistant to short circuits. This allows ER1025-94JR inductors to be used in high-reliability power equipment.

Conclusion

ER1025-94JR is a type of fixed inductor used in a variety of applications, such as DC/DC converters, high-frequency step-up and step-down voltage converters, and higher-frequency switching power supply units. Its working principle is based on the Faraday induction principle, and its key advantages include its high current capacity, large rated power, low internal resistance, small size, and light weight. ER1025-94JR inductors can be used in high-reliability power equipment due to its proven structure resistance to short circuits.
