Introduction

Fixed Inductors are an important component used in many electric and electronic applications, and they fulfill a variety of tasks. In this article, we will be examining the ER1641-202JP Fixed Inductor and its application field, as well as its working principle.

Features of the ER1641-202JP

The ER1641-202JP Fixed Inductor from Panasonic is a miniature, low-profile component. It has a rated inductance of 200µH ±20% and a rated current of 300mA. The ER1641-202JP has a maximum deviation of ±5% over its rated temperature range, from -40°C to +105°C. This product is RoHS Compliant and is an ideal choice for surface mounting applications.

Application Field

The ER1641-202JP can be used in a variety of applications, including in power supplies and in switching converters. It can also be used to reduce EMI/RFI interference and to provide additional protection for electronic components. Other applications of the ER1641-202JP include motion-controlled devices, automotive modules, communications equipment, and industrial machinery.

Working Principle

Fixed Inductors work on the principle of Faraday\'s Law, which states that a changing magnetic flux through a closed loop will induce an electromotive force (EMF) in the loop. The ER1641-202JP Fixed Inductor works by taking a direct current through its coil windings, which creates a magnetic field. This magnetic field then creates an inductor effect, causing the current to be delayed and forcing a voltage drop across the windings of the inductor. This principle is used in the ER1641-202JP to limit the current within a circuit and to reduce EMI/RFI interference.

Conclusion

In conclusion, the ER1641-202JP Fixed Inductor is a reliable and versatile component for a variety of applications. Its small size and low profile make it an ideal choice for surface mounting tasks, while its ability to reduce EMI/RFI interference and provide circuit protection makes it useful in a variety of industries. Its working principle is based on Faraday\'s Law, which states that a changing magnetic flux through a loop will create an EMF in the loop. The ER1641-202JP is a reliable and valuable component in many electronic and electric applications.
