Fixed Inductors

Fixed inductors are widely used components in electrical circuits. The inductors are an integral part of almost every application and serve many purposes like providing AC filters or transforming voltage. This article explains the characteristics, application fields, and the working principle of the CW160808-12NJ fixed inductor.

Characteristics

The CW160808-12NJ fixed inductor features a very low profile design of just 0.45mm. Its maximum current rating is 0.47A, and it is also heat and EMI resistant. The inductor has a good power/size ratio and it is RoHS, REACH and Halogen Free certified. The conductive pattern is made by printing silver palladium, which results in a stable quality, high reliability and excellent soldering.

Application fields

The CW160808-12NJ fixed inductor can be used in a variety of electronic devices and systems. It is most commonly used in modern DC-DC converters, automotive electronics, AC/DC circuitries, DVD applications, power switching circuits, high frequency power amplifiers, RFID applications, dynamic monitoring systems, computers, smartphones and other similar devices.

Working principle

Fixed inductors create a magnetic field when power is passed through the device. This magnetic field then induces a voltage to the secondary winding within the inductor, which is the main working principle of the device. The induced voltage is used to transfer the electrical current to other parts of the circuit. Fixed inductors often employ two or more coils—particularly the CW160808-12NJ designed—which helps to reduce stray inductance and minimize self-resonance frequency. When power is passed through the inductor, two fields are created: a primary field and a secondary field. Current flows between the two fields with minimal losses, allowing the inductor to efficiently transfer electrical energy.

Conclusion

The CW160808-12NJ fixed inductor is a widely used component for a range of applications in the electrical and electronic industries. Its low profile design, heat and EMI resistance, and good power/size ratio make it a reliable and efficient device. This article has also explained the basic characteristics of the device, its most common application fields, and its underlying working principle.
