Fixed inductors, or “broad band” inductors, are often used in radio frequencies, matching circuits, and power supplies for charge/discharge applications. The LQW15AN33NJ00D is a fixed inductor that has common applications in high currents and voltage circuits (i.e. switch mode power supply applications). It is a high power inductor that is used to condition power that has been switched from a high side (source) to a low one (sink).

The LQW15AN33NJ00D has a ferrite-cored inductor with a DC resistance rating of 0.5-2.5 ohms. It is also rated to operate in a range of DC to 300 MHz. It has an inductance of 33 nH and can tolerate currents from 0.25-5 Amps. This unit is also rated for a wide operating temperature of -40°C to +105°C.

The working principle behind a fixed inductor is relatively simple, as they rely on the magnetic field produced by the current passing through the inductor core. This magnetic field will store energy, which will then be released in the form of heat and light (dependant on the application). This energy release is controlled by the inductance, or the amount of energy released per change in electrical current. So, the higher the inductance, the more energy is stored within the unit.

The LQW15AN33NJ00D is suited for applications that require boosted current at higher frequencies and can prove beneficial for switching and linear operations, such as in controlling voltage. That said, it is well suited for use in high power switching circuits, power conditioning units, charge and discharge applications, as well as RF amplifier design. The unit is also well suited for power supplies, inverters and DC-to-DC converters.

Typical application schematic diagrams for the LQW15AN33NJ00D inductor are relatively simple and include connecting the inductor to both a voltage and ground source. It should also include a diode, to prevent reverse voltage, and a capacitor (depending on the application). The diode is important in the operation of the unit, as it prevents reverse voltage, while the capacitor helps to filter out any high frequency harmonics from the signal.

In summary, the LQW15AN33NJ00D is an ideal fixed inductor for applications that require high current and high voltage operations such as switch-mode power supplies. It has a ferrite-cored inductor construction with a DC resistance rating of 0.5-2.5 ohms, a wide operating temperature of -40°C to +105°C and can tolerate currents from 0.25-5 Amps. It is also rated to operate in a range of DC to 300 MHz. The working principle behind a fixed inductor is relatively simple, and it is normally connected to both a voltage and ground source and ought to feature a diode to prevent reverse voltage. The unit is ideally suited for high power switching circuits, power conditioning units, charge and discharge applications, as well as RF amplifier design.
