The LQH31HNR21K03L is a type of fixed inductor, which is widely used in various electronics applications. It is a small, high quality inductor that provides efficient and reliable electromagnetic energy storage and filtering of signals with medium to high frequencies. The inductor is capable of operating with very low insertion and return losses. It is also able to handle high peak currents and temperatures without compromising its performance.

The core of the LQH31HNR21K03L consists of a coil with an inductance value of 21.5nH, which is ideal for applications requiring low electrical resistance and low noise. It is housed in a small, lightweight package of 1.3mm diameter and 1.2mm height. This makes it well suited for use in densely populated PCBs. The inductor is also RoHS compliant and UL approved, ensuring safety. The component also has a wide operating temperature range of -40°C to 85°C.

The LQH31HNR21K03L is typically used in electronic circuits that require a combination of high current flow and filtering, such as power supplies, power amplifiers, switching regulators, DC-DC converters, and signal conditioning circuits. Its high Q factor provides excellent filtering performance. It is also used in wideband transformer feedback loops and RF impedance matching applications. The inductor can also be used in impedance matching circuits to reduce reflections and ensure that the signal reaches its intended destination with greater fidelity.

The working principle of the LQH31HNR21K03L is simple. Whenever an alternating current voltage passes through the inductor, an inductive reactance is generated, which opposes the flow of current. At a given frequency, the reactance increases with increasing value of the inductance. Therefore, when the current passes through the inductor, the amount of voltage drop is proportional to the inductance value and current. This phenomenon is used to filter signals according to their frequency.

The LQH31HNR21K03L is a great choice for filtering medium to high frequency signals securely and efficiently. It is also an ideal component for applications requiring low electrical resistance and low noise. Its small size and lightweight make it suitable for use in densely populated PCBs. It has a wide operating temperature range and is RoHS compliant and UL approved, ensuring safety and reliability.
