Introduction

The HKQ0603S3N9C-T is a surface-mount, fixed inductor. It is manufactured by TDK Corporation and is part of the SRF series of fixed inductors. This series is designed to provide high frequency performance, low DC resistance and high inductance values.

Application Field

The HKQ0603S3N9C-T is a versatile component suitable for a wide range of applications. Its surface-mount design makes it well-suited for use in circuit board designs where space is limited. It has a wide inductance range, from 0.28 to 7.7nH, enabling it to be used as a high-frequency power supply filter circuit, a DC-DC converter, a resonator for a high-frequency signal, or a tying component in an impedance matching circuit. In addition, it can be employed in a number of general purpose and RF applications, such as in tuners and high-frequency antennas.

Working Principle

An inductor is an electrical component that utilizes the relationship between a magnetic field and an electric current to store energy. In short, when a current is introduced into an inductor, it produces an electromagnetic field around its winding. This field generates a back-EMF which has a voltage that is proportional to the inductor\'s rate of change of current. As a result, a change in current will cause the inductor’s back-EMF to oppose the change, inducing a resistance to the current.

The HKQ0603S3N9C-T is a fixed inductor, meaning that it has a set inductance value. This means that when a current is introduced, a fixed voltage opposing the current will be induced, which will remain constant as long as the current does not significantly fluctuate. This makes it ideal for components such as a high-frequency power supply filter circuit, where a fixed voltage can effectively reduce the ripple voltage.

Features

The HKQ0603S3N9C-T has a variety of features that make it a suitable choice for a wide range of applications. It has a high Q Value of 82 min. (at 100MHz), allowing it to be used at high frequencies without significant signal loss. This means that it is well-suited for high-frequency signal resonators and impedance matching circuits. Its small size (0603) and low DC resistance (2.3 mΩ typ.) also make it suitable for applications where space is limited.

In addition, its wide inductance range (0.28 to 7.7 nH) allows it to be used for a number of purposes. It can be employed in a DC-DC converter for step-down functions, or as a filter in a high-frequency power supply for filtering purposes. Its high frequency performance makes it suitable for a variety of general purpose and RF applications.

Conclusion

The HKQ0603S3N9C-T is a versatile component well-suited for a wide range of applications. Its small size and low DC resistance make it an ideal choice for high-density circuit board designs. Its wide inductance range makes it suitable for a variety of general purpose and RF applications, such as in tuners, high-frequency antennas, DC-DC converters, and high-frequency power supply filters. Its high Q Value of 82 min. (at 100MHz) makes it an ideal choice for high-frequency signal resonators and impedance matching circuits. As a result, the HKQ0603S3N9C-T fixed inductor is an ideal choice for a variety of purposes.
