Fixed inductors are a type of inductor used in electrical circuits, often for the purpose of providing static inductance in an alternating current circuit. They are available in various forms and current ratings, making them suitable for a range of applications. One example of a fixed inductor is the ER1641-182JM, which is a low-profile, cost-effective surface-mount inductor suitable for ceramic and PCB applications.

ER1641-182JM Overview

The ER1641-182JM is a low-profile, 18nH inductor manufactured by The Electronics Line, which is a subsidiary of Yamatake Corporation. It features low cost, high current handling, and good frequency characteristics. This makes it a good choice for applications requiring frequency compensation, such as oscillators and amplifiers. It is a ceramic-core inductor with a footprint of 2.6x2.9mm. It has an operating temperature range of -40°C to +125°C. The inductance tolerance is ±30%, while the DCR range is from 0.45Ω to 0.75Ω, depending on the batch.

Applications

The ER1641-182JM is a versatile inductor that can be used in a wide range of applications. It is suitable for use in oscillators, amplifiers, signal processing circuits, and switching power supplies. It is also suitable for use in ceramic and PCB assemblies, providing excellent ESD, surge, and RF protection. The ER1641-182JM is also well suited for use in automotive applications due to its low-profile design.

Working Principle

The ER1641-182JM is a fixed inductor, meaning it has a fixed inductance value since it does not require any external energy source. It works on the principle of Faraday\'s law, in which a voltage is induced in an inductor when the current flowing through it changes. The inductor stores the energy in the form of a magnetic field, which is released when the current changes. The inductance value of the ER1641-182JM is 18nH, meaning that it will produce 18nH of inductance in the presence of a varying current.

Advantages

The ER1641-182JM provides a cost-effective solution for applications requiring low-profile, accurate inductors. Its small footprint and wide operating temperature range make it suitable for use in high-density PCBs and automotive applications. The ER1641-182JM also features a high current-handling capability and excellent ESD and surge protection. Furthermore, it offers high accuracy and stability, making it suitable for use in a range of signal processing and switching power supply applications.

Conclusion

The ER1641-182JM is an excellent choice for a range of high-accuracy inductor applications due to its low profile, cost-effectiveness, and high current-handling capabilities. It is suitable for ceramic and PCB assemblies, and the wide operating temperature range makes it suitable for automotive applications as well. The ER1641-182JM also provides excellent ESD and surge protection, making it an ideal choice for signal processing and switching power supply applications.
