Introduction of Fixed Inductors

Fixed inductors are electronic components used to store electrical energy in an electromagnetic field in a circuit. They may also filter electronic signals, decrease voltage surges, control power dissipation, or provide loop stability for circuits. Due to their relatively low cost and ease of use, fixed inductors are used in many electronic products, including cell phones, computers, radios, medical imaging equipment, and automotive applications.

Application of LQW2BHN15NK13L

The LQW2BHN15NK13L, manufactured by Murata Electronics, is a fixed inductor designed for applications ranging from low frequency to high frequency DC/DC converters. It has a high current rating, low DC resistance, and an inductance range from 0.3 μH to 1.5 μH. The LQW2BHN15NK13L is also designed to be used in power supply circuits, dc/dc converters, automotive circuits, and electronic equipment.

Design and Performance

The physical size of the LQW2BHN15NK13L is 4mm x 4mm x 2.5mm and it uses four flat pins for mounting. The device is made of ceramic and is RoHS compliant. Other features of the device include excellent radiator heat dissipation, high responsiveness, and low noise. It also has a wide operating temperature range, from -40°C to 125°C, and can handle up to 3.2A continuous current.

Working Principle of LQW2BHN15NK13L

The LQW2BHN15NK13L is a fixed inductor that works by converting a varying input current into a fixed magnetic field. When an alternating current (AC) is applied to the coil, the magnetic field will follow the changing current. This produces an electromotive force (EMF), which induces a voltage across the coil. The magnitude of the current in the coil will depend on the inductance of the coil and the frequency of the applied current.The LQW2BHN15NK13L is designed to provide a high inductance, which helps to filter incoming electrical signals and reduce radio frequency interference (RFI). When the input signal\'s frequency is below the resonance frequency of the inductor, the inductor acts like a resistor, allowing only a small portion of the signal to pass through. When the input frequency is above the resonance frequency, the inductor acts like a capacitor, allowing the signal to pass through.

Conclusion

The LQW2BHN15NK13L is an excellent choice for applications ranging from low to high frequency DC/DC converters, power supply circuits, automotive circuits, and electronic equipment. Its physical size and four flat pins make it easy to install, and its high inductance, low noise, and wide operating temperature range make it a reliable choice for high performance applications. The LQW2BHN15NK13L works by converting a varying input current into a fixed magnetic field, which produces an emf and allows for filtering of incoming electrical signals, as well as reduction of RFI.
