Fixed inductors are some of the most widely used electronic components found in electronic circuits. Fixed inductors can be thought of as some of the most basic elements for creating reactive circuits that rely on varying electromagnetic fields set into motion to store energy. A DR124-3R9-R is one such component, often used for a variety of purposes across a wide range of projects.

Application: DR124-3R9-R is a no-lead fixed inductor with an inductance value of 3.9uH and a current rating of 450mA. It is typically employed in a variety of applications such as filters, tuners, converters, delay lines and DC/DC converters. It is also commonly used in up-to-date project and for projects involving high frequencies like radio transmitters and receivers.

Working Principle: A fixed inductor such as the DR124-3R9-R operates on the principle of inductance which is the ability to store and release energy in the form of a changing magnetic field. The inductor is composed of a tightly wound coil of wire which, when alternating current is passed through it, creates an electromagnetic field. Each time a current is passed through the inductor, energy is stored in the form of this electromagnetic field and when it is released, it becomes a reversed current and the energy is discharged in the form of voltage pulses.

Fixed inductors such as the DR124-3R9-R are used to regulate voltage and current in many electronic devices, and are fundamental components in both AC and DC circuits. They are commonly used to create time delays, filters, impedance matching, signal transformation, and signal amplification. They are also commonly used in oscillators to give a shifting frequency output.

The DR124-3R9-R fixed Inductor is mainly employed in DC-DC converters and power supplies due to its high current rating. It is also widely used in audio applications such as musical instrument amplifiers, preamplifiers, and headphone amplifiers, as well as for wireless communications such as radio transmitters and receivers. Additionally, the fixed inductor is often used for shielding devices like RFID tags, radio frequencies, and Wi-Fi applications.

In summary, the DR124-3R9-R is a no-lead fixed inductor with a high current rating suitable for a range of applications. It is mainly employed in DC-DC converters and power supplies. It is also popularly used in audio, radio frequency, and Wi-Fi applications. It operates on the principle of inductance, in which energy is stored in the form of a changing magnetic field and discharged in the form of voltage pulses when a current is passed through the inductor.
