Fixed Inductors

Fixed inductors, also known as chokes, are passive components that store energy in the form of a magnetic field. They are useful for blocking or suppressing both high frequencies and low frequencies and also for stabilizing current in circuits. The most common type of fixed inductor is the air core, which is made up of conductive wire wound around a non-conductive core. Other types of fixed inductors include ferrite core inductors, iron core inductors, and coil-loaded inductors. The specific type of inductor used in a circuit depends on the application.

LQH43CN1R8M33L Application Field and Working Principle

The LQH43CN1R8M33L is an air-core, fixed inductor that is designed for use in a variety of circuit applications. It is a non-polarized, three-terminal inductor, with the terminals being either soldered or connected with a clip. Because of its low profile, the LQH43CN1R8M33L is widely used for surface mount or hybrid circuits and can be used in a variety of frequencies.

The inductor works by producing a magnetic field within a coil of wire when a current is passed through it. The field produced generates an opposing, self-induced voltage that is proportional to the changing current. This opposing voltage opposes the original applied voltage, creating a frequency-dependent voltage drop, resulting in the inductor temporarily storing energy. The stored energy will be released after the alternating current is stopped.

The inductance of an inductor is determined by the wire winding around the core and is measured in Henries. The inductance of the LQH43CN1R8M33L is 8 milli-Henries, and its operating temperature ranges from -40 to 85°C. It has a maximum current rating of 1.2A, a saturation current of 5.0A, and an equivalent series resistance of 6.9Ω.

The LQH43CN1R8M33L can be used in multiple applications such as motor control circuits, filter networks, and frequency control circuits. In motor control circuits, it is used to protect the motor from excessive current by providing a drop in the supply voltage. Along with other components, it can also be used in filter networks as single or multiple resonant circuits to filter and attenuate certain frequencies. In frequency control circuits, such as PLLs or oscillators, the LQH43CN1R8M33L is used to stabilize the current and help maintain the desired operating frequency.

The LQH43CN1R8M33L is a widely used fixed inductor that provides low profile size and has a wide range of applications. It is designed to help provide a frequency-dependent voltage drop, which is useful in various circuit applications. Understanding how it works and how to use it correctly will help ensure the best performance from the component and the circuit.
