Fixed Inductors

Fixed inductors are essential components in a wide range of applications. From filter networks, tuned circuits, motor control and timing devices, power supplies and power converters, switching regulators and DC-DC converters to RF networks and telecommunications systems, the list of applications is varied and far-reaching. It is therefore important to be aware of the features, capabilities and limitations of the various types of fixed inductors available. In this article, we focus on the AIRD-01-680K fixed inductor and its application field and working principle.

Description of the AIRD-01-680K

The AIRD series fixed inductors from TDK are designed to meet a wide range of requirements. These products provide high power efficiency and reduced inductance as well as current capacity and resistance to mechanical shock. The AIRD-01-680K is a high-performance, single-layer, molded shield fixed inductor that is designed to meet various current and power requirements. This inductor offers a 10.6A current capacity, a 680uH inductance, a 0.15 ohms DC resistance, and a 0.66 (max) relative q-factor.

Applications of the AIRD-01-680K

The AIRD-01-680K’s high power efficiency makes it suitable for a variety of applications. Its core and shield structure enable it to be used in switch-mode power supplies, active filters, and DC/DC converters. Additionally, this fixed inductor can be used in line reactors, snubber circuits, and voltage regulator circuits.

Working Principle

The working principle of the AIRD-01-680K is based on electromagnetic induction. This means that when an electrical current is passed through the inductor, a voltage is induced or generated that is proportional to the rate of change of the current. This induced voltage opposes the original current, creating a damping effect that is referred to as inductance. The higher the inductance or opposition to change in current, the higher the voltage generated across the inductor. The AIRD-01-680K fixed inductor has a relatively high relative q-factor of 0.66, meaning that it is able to oppose a high rate of change in current while still having low relative resistance to the current. This makes it an ideal choice for applications that require high power efficiency.

Conclusion

The AIRD-01-680K fixed inductor is a high-performance component suitable for a wide range of applications. Its core and shield structure, high power efficiency, and relatively high relative q-factor make it an excellent choice for various power electronic applications. As such, it can be considered an invaluable component in many modern electronic systems.
