Fixed Inductors

A fixed inductor is an electrical device designed to store energy in a magnetic field when electric current passes through it. The AIRD-02-121K fixed inductor is a ceramic-based device with a high inductance value. It is typically used in applications such as power supply, RF amplifiers, and signal processors.

Overview

An AIRD-02-121K fixed inductor is a component that consists of two separate coils that are securely attached to a ceramic body. Each coil has an individual winding and the coil ends are connected to the ceramic body by a lead-free epoxy. The coil and ceramic body both have their own layers of protective insulation. This design keeps the coil protected and keeps any unwanted currents away from the device.The AIRD-02-121K is primarily used for low loss, high inductance applications. It has a rated inductance of 1210 nanowatt-meters. It has a wide frequency range from 20MHz to 500MHz, with low DC resistance and high Q-factor. Its rated current is 33.5mA and it has a rated voltage of 15V.

Application Field

The AIRD-02-121K is a popular fixed inductor due to its high inductance value and long life. It is used in a variety of applications, such as power supplies, RF amplifiers, signal processors, base stations, and automotive systems. It can also be used in digital circuits, such as switching regulators, digital to analog converters, and clock boards.

Working Principle

Just like other inductors, a fixed inductor works by creating a magnetic field when an electric current passes through it. When alternating current (AC) is applied to the inductor, a varying magnetic field is created and this is what stores the energy in the coil. The inductor also has an inductance value, which is a measure of how much energy is stored in the coil.When a direct current (DC) is applied to the inductor, the energy stored in the magnetic field is released back into the circuit. This means that the inductor can act as both a storage device and a voltage regulator. It can smooth out voltage levels and reduce unwanted voltage spikes.In the case of the AIRD-02-121K, it is a fixed inductor which means that it cannot be adjusted. However, the device still functions as an alternate current source, as it stores energy in the coil when AC is applied and releases energy back into the circuit when DC is applied.Overall, the AIRD-02-121K is a reliable fixed inductor that is ideal for low loss, high inductance applications. Its rated inductance of 1210 nanowatts-meters makes it a great choice for applications such as power supplies, RF amplifiers, signal processors, base stations, and automotive systems. Thanks to its durable design and long life, it is sure to provide reliable performance for many years.
