Fixed Inductors

Introduction To LQW Series Layout

The LQW15AN4N3C00D, manufactured by TDK, is a fixed inductor with a 3x2.6x2.2mm body size that makes it suitable for use in consumer and industrial electronics. It is constructed of high quality copper coil wire (magnetically shielded) and its electrical characteristics make it suitable for use in applications like DC/DC converters, switch mode power supplies, filter circuits, actively actuated voltage amplification mismatching circuits, and noise reduction circuits, due to its low DC resistance, high inductance stability, and great operational temperature ranges (temperatures between -40°C to +105°C). It is important to note that this type of inductor should be connected according to the direction clearly indicated by its pin layout.

Working Principle Of LQW Series Layout

An inductor is a passive electronic component made up of coils of wire that stores energy in the form of a magnetic field when an electric current passes through it. An inductor is used in circuits to control the flow of the current by increasing or decreasing its resistance levels. The LQW15AN4N3C00D is an inductor built around a core, commonly used in consumer electronics, telecommunications, and automotive systems, as well as other passive electronic devices.When there is AC current in a fixed inductor, an opposing magnetic field is created by the current. This field creates an opposing voltage that rises in direct proportion to the rate of change in current. This opposing voltage effectively limits the current, thus providing an inductance. This inductance can be anywhere between 1uH and 1mH, depending on the size, current, and self-capacitance of the LQW15AN4N3C00D. The inductor also features an ic flux adjustment feature, which can be used to adjust the self-resonance frequency of the inductor by shifting the field inside the core, influenced by the shape of the coil. This in turn affects the frequency of AC current passing through it, allowing the user to adjust the performance of the inductor for specific applications.

Application Fields Of LQW Series Layout

The LQW15AN4N3C00D fixed inductor is suitable for use in a number of different applications. Its high inductance stability and wide operational temperature ranges make it ideal for DC/DC converters, switch mode power supplies, filter circuits, voltage amplification mismatching circuits, and noise reduction circuits. It is also widely used in many telecommunications and automotive systems, such as mobile phones, radios, automotive alternators, and home audio systems, due to its ability to decrease the supply voltage ripple and reduce its losses. In audio systems, the inductor is used to produce low impedance for drive amplifiers and to improve the sound level.The inductor can also be used in low noise signal processing circuits, such as amplifiers, Oscillators, and transmission lines. When used in switching power supply circuits, the LQW15AN4N3C00D is able to reduce the values of the peak current and the peak voltage, thus allowing the system to work more efficiently and increase its power output.

Conclusion

In conclusion, the LQW15AN4N3C00D is an ideal fixed inductor for a wide range of applications. Its high inductance stability, wide operating temperature range, and adjustable self-resonance frequency, make it suitable for use in switching power supplies, telecommunications, automotive systems, and audio systems, as well as DC/DC converters, filter circuits, and noise reduction circuits. The adjustable IC flux adjustment feature can be used to tune the inductor\'s performance to specific conditions, while the fact that it is composed of high quality copper wire and is magnetically shielded, makes it a reliable and highly capable inductor for a variety of applications.
