Fixed Inductors

Fixed inductors, like other forms of inductors, are passive electrical components used in many fields from electronics to telecommunications. A fixed inductor, specifically the LQH3NPN2R2NM0L, is a surface mount, standard inductor manufactured by Murata that can often be seen in digital and audio circuits. The LQH3NPN2R2NM0L is one of the most common and widely used of its type, widely praised for its excellent noise reduction, temperature coefficient, and low cost.

Application Fields

The fixed inductor type LQH3NPN2R2NM0L can be found in many different types of electrical equipment, but is most often seen within consumer electronics. Audio products such as receivers and amplifiers are some of the best applications for it, while digital equipment such as computers have recently incorporated it into their electronic circuitry. The LQH3NPN2R2NM0L is also becoming increasingly popular in the telecommunications industry, where it is used to reduce interference and improve signal quality.

Working Principle

The working principle of a fixed inductor is the same as that of other types of inductors. It consists of an electrical conductor, usually a coil of wire, wound around a core material, usually a ferrite or iron, and connected to an external circuit. When a current flows through the coil, it creates a magnetic field around the coil, which causes an inductance. This inductance adds resistance to the circuit, resulting in the desired electrical effect.

The inductance of the LQH3NPN2R2NM0L is, as stated on the Murata website, measured to be 2.2uH ±20 percent. This is considerably higher than other inductors on the market, meaning it can be used to reduce more electrical disturbances and noise. It also features lower DC resistance and thermal shock, as well as being able to operate at temperatures ranging from -40 to +85 degrees Celsius.

The LQH3NPN2R2NM0L is able to provide outstanding noise reduction, and is an ideal component for audio applications, such as A/V receivers and amplifiers, as well as digital circuits. The low cost, high performance and reliability of the LQH3NPN2R2NM0L makes it a popular choice for many applications.
