Fixed Inductors

Fixed inductors, also known as chokes, are passive components that store energy in the form of a magnetic field. Inductors are used to block direct current (DC) signals while allowing alternating current (AC) signals to pass, thus preserving the integrity of the power supply or signal lines. The NLV32T-221J-EF is a fixed inductor from the NLV32T Series that is designed to be used in consumer and industrial electronic devices.

Specifications

The NLV32T-221J-EF has a variety of specifications including a nominal inductance of 220 micro-henry, an operating temperature range of -40°C to +125°C, and a high saturation current rating of 1.6 amps. It also has a tolerance of 10% and a resistance of 22 mOhms. The inductor is available in a SMT package that measures 4.5 mm x 3.2 mm with a height of 1.49 mm. The anti-ESD protection is rated from 500 V to 8 kV.

Application Fields

The NLV32T-221J-EF inductor has multiple applications including power supplies, DC-DC converters, switched-mode power supplies, and uninterruptible power supplies. It is well-suited for use in switching power supplies, audio equipment, AM/FM tuners, and LCD displays. It is often used to reduce high frequencies and acts as a filter in the application. Additionally, they are also used to guide and adjust current in leaded and lead-free applications.

Working Principle

The working principle of a fixed inductor is based on the same phenomena as other inductors such as transformers. It is made up of coils of wire wrapped around a core material. When a current flows through the wire, it produces a magnetic field that stores energy. As the current increases or decreases, the magnetic field expands or contracts, creating a change in the amount of voltage in the coil. This is known as inductance and is measured in units of henries. The NLV32T-221J-EF has a nominal inductance of 220 micro-henries.

Inductors also have a property known as resistance. This is the same as the resistance of other electrical components such as resistors, and is measured in ohms. The resistance of the NLV32T-221J-EF is 22 mOhms. This is used to limit the current flowing through the inductor, and protect the device from damage.

When used in electronic circuits, fixed inductors can act as a filter, smoothing out high frequency signals, and allowing certain types of signals to pass while blocking others. This can be used to reduce interference and noise in power lines, preventing them from affecting the performance of other components.

Conclusion

The NLV32T-221J-EF is a fixed inductor from the NLV32T Series that is designed for use in consumer and industrial electronic applications. It has a nominal inductance of 220 micro-henries, an operating temperature range of -40°C to +125°C, and a tolerance of 10%. It is well-suited for use in switching power supplies, audio equipment, AM/FM tuners, and LCD displays, and can be used to reduce noise and interference in power lines. The working principle is based on the same phenomena as other inductors, and it is made up of coils of wire wrapped around a core material. When a current flows through the wire it produces a magnetic field that stores energy.
