Fixed inductors are electronic components, primarily found in alternating current (AC) circuits. They are commonly used in high-frequency applications such as radio frequency (RF) circuits and in power applications. Fixed inductors, commonly referred to as chokes, are used in a variety of industries such as aerospace, defense, medical, automotive, consumer electronics, and industrial controls. Fixed inductors are also used in power supply and AC adapter circuits to minimize power losses.

The LQW15CAR43K00D is a 15 μH surface mount, wirewound, ceramic enclosed inductor. This device is part of the LQW series of fixed inductors from Murata Manufacturing and is a widely used component in the electronics industry. The LQW15CAR43K00D is an ideal choice for a range of AC circuits, from high-speed digital and switching circuits to power supply and adapter applications. The wires used to create the inductive coil are thickly plated with a low resistance solder, creating a high power, low resistance component.

The working principle of the LQW15CAR43K00D is based upon the electric induction theory. Electric induction is the process in which a voltage is induced in a conductor without a direct electrical connection between the two. In the case of the LQW15CAR43K00D, the magnetic flux created by the conductors when current is applied causes a voltage to be induced in the second conductor. This induced voltage is proportional to the rate of change in the current and is known as self-induction. This self-induction creates a current in the opposite direction of the original current, which reduces the overall current in the circuit.

The LQW15CAR43K00D can also be used for power supply or AC adapter applications, where it acts as a filter. The inductor’s ability to absorb energy prevents power losses, thus increasing efficiency and reducing power consumption. Additionally, the use of the LQW15CAR43K00D in these applications can prevent radio frequency interference (RFI) and electromagnetic interference (EMI).

The LQW15CAR43K00D has a rated current of 4.1 Amps, resistance of 0.6 mOhms, and tolerance of +/– 10%. The inductor is rated for operating temperatures between -55 °C and 130 °C and is available in a variety of packages, including an automated assembly-friendly SST series. The inductor is a lead-free, RoHS compliant part and is qualified to meet MIL-PRF-39001, Class W requirements.

In summary, the LQW15CAR43K00D is a 15 μH surface mount, wirewound, ceramic enclosed inductor. It is an ideal choice for high-speed digital, switching, power supply or adapter applications. The working principle of the LQW15CAR43K00D is based on electric induction and self-induction, which creates a current in the opposite direction of the original current, thus reducing the overall current in the circuit. The inductor is available in various packages, has a high power, low resistance, is lead-free, RoHS compliant, and is qualified to meet MIL-PRF-39001, Class W requirements. Therefore, the LQW15CAR43K00D is a versatile and reliable choice for fixed inductor applications.
