Fixed inductors are used in a variety of electrical circuits and applications, from simple power supplies to complex electronic circuits. The NLV32T-680J-PF is a fixed inductor and part of the NLV32T series from TDK. As with all fixed inductors, this specific one has an application field and a working principle.

Application Field

The NLV32T-680J-PF is a low voltage wire-wound SMD inductor with a relatively high impedance of 680Ω. This makes this inductor suitable for applications from DC/DC converters, power supplies, and filters to switching regulators and other applications that require a low profile. With the many different types of inductor, the application field is wide enough to encompass current sensing, voltage stabilisation, soft start, motor drive, and any other variation or purpose that requires the use of an inductor.

Working Principle

The working principle of the NLV32T-680J-PF is fairly straightforward. When a current is applied to the inductor, it stores energy in a magnetic field that is created around its windings. The stored energy then opposes the applied current, so the current flow through the inductor is increased. This, in turn, creates a higher voltage drop across the inductor, allowing it to work efficiently even at very low voltages. Additionally, the larger the inductor, the higher its inductance. This will result in more current being stored in the magnetic field, and hence, a higher voltage drop across the inductor.

The NLV32T-680J-PF also has a high core-loss coefficient, which is an indication of its good thermal efficiency. This means that it is capable of handling more power and performing better at higher frequencies. It also features a more efficient cooling scheme due to its unique construction, which is why it is often used in power supplies.

Conclusion

The NLV32T-680J-PF is a fixed inductor that is well suited for a wide range of applications. Its high impedance makes it suitable for applications from DC/DC converters and power supplies to switching regulators. Additionally, its unique construction features a high core-loss coefficient for good thermal efficiency and efficient cooling. This makes the NLV32T-680J-PF a powerful choice for applications in need of a robust and reliable inductor.
