Fixed Inductors are components that are commonly used in many electronic circuits and are especially important in RF circuits. The LQW04AN3N0D00D is a type of Fixed Inductor manufactured by TDK Electronics. This article will explore the application field and working principle of the LQW04AN3N0D00D.

The LQW04AN3N0D00D is a general-purpose Fixed Inductor designed for use in DC-DC converters, switched power Converters, and other low-frequency, high-efficiency circuits. It is a low-profile and small-size inductor, making it easy to mount on a circuit board. It is constructed using a RoHS compliant miniature structure, with a core made of metal alloy and an air gap for maximum efficiency.

In terms of maximum specifications, the LQW04AN3N0D00D can provide up to 30uH of inductance at up to 50mA of current at up to 1 MHz of frequency. It has an operating temperature range from -40℃ to 85℃ and can withstand a high voltage of 100V. In terms of DC resistance, the device has a DC resistance of up to 0.72 ohms.

The working principle of the LQW04AN3N0D00D is based on the principle of electromagnetic induction, in which a voltage is induced in a conductor when it passes through a changing magnetic field. When power is applied, current flows through the metal core of the component, creating a magnetic field. This magnetic field passes through the air gap creating a voltage across the winding, which causes a change in the flow of current. In the case of the LQW04AN3N0D00D, the magnetic field generated by the current in the metal core induces a voltage in the winding, resulting in a inductance that can be used to regulate the current flow in the circuit.

The main applications of the LQW04AN3N0D00D are in low-frequency DC-DC converters, switched power converters, and other high-efficiency circuits. The inductance provided by the component can be used to regulate the current and reduce power dissipation in the circuit. It can also be used to reduce EMI interference, which is important in applications where high-speed signals are required. Additionally, the low profile and small size of the component make it suitable for compact designs.

In conclusion, the LQW04AN3N0D00D Fixed Inductor is a general-purpose low-profile component that is especially useful in low-frequency, high-efficiency circuits. The device is constructed using a RoHS compliant miniature structure with a metal alloy core and an air gap for maximum efficiency. It has a maximum specification of 30uH at 50mA at 1MHz and can withstand a high voltage of up to 100V. The working principle of the device is based on the principle of electromagnetic induction. The main applications of the LQW04AN3N0D00D are in low-frequency DC-DC converters, switched power converters, and other high-efficiency circuits to reduce EMI interference and increase power efficiency.
