LQH66SN103M03L

Fixed inductors are used widely in electrical and electronic circuits for filter constructions, resonator tank circuits, tuning, chokes, and many other applications. Covered under this definition are inductors with ferrite cores, carbon cores, permalloy cores, or air cores. Fixed inductors are a type of electronic component that uses a magnetic field to store electrical energy.

LQH66SN103M03L is a fixed inductor, specifically an air core inductor, and is used mainly in radio frequency applications. Air core inductors are limited generally to low power, audio frequency, and radio frequency applications, where they are extensively used as impedance matching devices. They can also be used in RF oscillators.

The construction of the LQH66SN103M03L consists of two parts: a coil winding of enameled copper wire around a non-magnetic core, and a package with epoxy. The core in this device does not have a magnetic material, and it is used to help shape and protect the wire. The epoxy in the package acts as a seal and helps maintain a stable state of the component, preventing it from coming apart when under extreme temperatures.

LQH66SN103M03L is designed to function by using the principle of electromagnetic induction to induce a voltage in the coil winding. When a current is passed through it, a magnetic field is created around the winding, which in turn induces a voltage in the winding. The same current will then create a corresponding magnetic field, inducing a current opposing the original current. This is known as the inductive reactance, which is used to regulate electric current.

The device has an inductance of 66nH and a Q-factor of 20. The higher the Q-factor, the greater the attenuation of signals over a given frequency range. The LQH66SN103M03L can handle currents up to 1A and is rated for frequencies up to 30MHz. It can also tolerate temperatures between -40°C and +125°C.

In conclusion, the LQH66SN103M03L is an air core inductor that belongs to the category of fixed inductors. This device utilizes the principle of electromagnetic induction to induce a voltage in the coil winding when an electric current is passed through it. The device is rated for currents of up to 1A and frequencies of up to 30MHz, and can tolerate temperatures between -40°C and +125°C.
