Fixed inductors, also known as fixed or trimmable inductors, are components used to support the inductive-capacitive circuit number in a wide variety of electrical and electronic projects, such as audio visual systems, electronic circuits, data acquisition systems and communications systems. A popular device used in this application is the LB2518T150K fixed inductor, manufactured by Lite-On.

The LB2518T150K is an SMD-type fixed inductor with a shielded construction. It has a inductance of 150uH, rated current of 38.5A and a rated temperature of 85 degrees Celsius. The LB2518T150K is designed to withstand a high vibration environment and its operating temperature range is from -40 to 85 degrees Celsius. The device has a fairly low profile of only 6mm, making it easy to use in confined spaces.

The primary application for the LB2518T150K is in switching power supply circuits. The inductor works as part of a resonant circuit to convert the incoming power supply input into the output voltage. The inductor serves as an energy store during the off cycle of the switching, before releasing it in the on cycle. This energy is then consumed at the load side of the power supply circuit.

The LB2518T150K\'s working principle relies on Faraday\'s law, which states that the induced electromotive force (EMF) in a circuit is equal to the total rate of the magnetic flux change. A magnetic field is created when current flows through the inductor wire. As the current is switched off, the change in the magnetic field generates an induced EMF. The EMF is then converted into an output voltage across the load.

The LB2518T150K is an ideal inductor for switching power supply applications. Its shielded construction helps reduce the effects of external electromagnetic interference (EMI) as well as improve its thermal properties. Its low profile design allows the device to be safely used in enclosed spaces, making it a practical choice for power supply engineers.
