Fixed inductors, also known as inductors, are electronic components used for storing electric charge and electrical energy, and are generally used in combination with resistors or capacitors to form an LC oscillation circuit. An example of a fixed inductor is the HLQ021R3BTTR. It is designed to be suitable for mobile phones, tablet computers, PCs and other products applications.

The HLQ021R3BTTR is an integral part of any mobile phone, tablet computer, or personal computer circuit. It features a wide range of standard inductances ranging from 0.47μH to 1.0μH for optimal device performance. The operating temperature range is −40 °C to +105 °C with a maximum ripple current of up to 100mA. In addition, it has a high inductance tolerance of ±20%, a high Q value of up to 22 at 1 MHz, an array of 2.52X2.20mm in size, and a mounting method of device with top coplanar.

The working principle of the HLQ021R3BTTR fixed inductor relies on the generation of a magnetic field by the current coming through it. This magnetic field induces a voltage across the inductor, which is an electromotive force. This force is proportional to the amount of current flowing through the device. As the current increases, so does the amplitude of the voltage, and as the current decreases, the amplitude of the voltage does too. This property is useful for filtering and current limiting applications as well as for examples such as in high-frequency switching power supplies and wireless LAN antennas.

The HLQ021R3BTTR fixed inductor has a number of different application fields. In order for it to be used in mobile phones, table computers and other products, utilising the current to generate a voltage is of great importance. It provides a robust and reliable filtering capability for circuits, ensures a low noise power supply, and maintain a stable current flow. It can also be used in low-noise amplifier applications, transformer feedback circuits, RF and microwave circuits, and many other applications related to high-frequency signal processing, including in amplifiers and oscillators.

Which application of the HLQ021R3BTTR fixed inductor is suitable for any particular circuit depends on the specific design requirements. However, its wide range of standard inductances, high inductance tolerance, and high Q value all contribute to its significant versatility and flexibility, making it applicable for a wide range of applications. In addition, it utilises a robust and reliable construction method which allows it to be highly durable, making it the ideal choice for a wide range of applications.
