Fixed inductors, also known as “chokes”, are electronic components used in a wide variety of applications. The LQW15ANR10J00D is a fixed inductor manufactured by Murata Electronics, capable of handling high current loads and designed for use in high-power applications, such as transmitters, power converters, and motor drives. This article will discuss the application fields and working principles of the LQW15ANR10J00D.

The LQW15ANR10J00D is a molded ferrite inductor with a lead-free pure tin finish and a 4mm x 6mm footprint. It has a rated inductance of 10uH, a rated current of 15A, and a rated DC resistance of 0.71 ohms. It is capable of handling frequencies up to 10MHz, and can operate over a wide temperature range of -40 to +125C.

The LQW15ANR10J00D finds use in many different applications, such as power converters, motor drives, audio frequency (AF) and radio frequency (RF) applications, DC/DC converters, and cellular base station power amplifiers. It is also suitable for radio interference suppression, and is used in medical imaging equipment, such as MRI and CT scanners.

The working principle of the LQW15ANR10J00D is based on Faraday\'s law of induction. When a variable electrical current flows through a conductor, it creates a magnetic field in the vicinity of the conductor. This magnetic field induces an electromotive force (EMF) in the conductor, which opposes the change in the current. This opposing EMF is the inductance.

The LQW15ANR10J00D utilizes this concept to store energy in the form of a magnetic field and maintain a steady current over changes in load. It does this by dampening the fluctuations in the current by converting them into an EMF, which helps to minimize the ripple in the DC output and ensure smooth operation. As a result, the inductor can absorb changes in load and sustain its output.

In addition, the inductor allows for easier ramp up of AC currents. The inductance of the LQW15ANR10J00D creates an inertia-like effect, which helps to slow down the current rise-time and lower the peak, resulting in a smoother, more gradual rise in current. This is highly beneficial for applications such as motor drives, in which an abrupt current increase can cause damage.

The LQW15ANR10J00D is a high-power fixed inductor suitable for use in a variety of applications. Its Faraday\'s law-based working principle allows it to store energy in a magnetic field and absorb changes in load, making it an indispensable component for power converters, motor drives, and other high-power applications. It is capable of handling frequencies up to 10MHz, and can operate over a wide temperature range of -40 to +125C.
