Fixed inductors are passive components that are made up of a coil of wire around an iron core or some other magnetic material that stores energy. They are used in a variety of circuits, including power supply, filter, and signal conditioning applications.

The LB2518T100K is a fixed inductor from Sumida that can be used in a variety of applications. It is designed specifically for a wide range of applications, including high frequency filter networks, switching power supply circuits, battery charging applications, and switching regulators.

The LB2518T100K can be used in both alternating current (AC) and direct current (DC) circuits. It is a low profile, toroidal design with a winding ratio of 1:1. The device is constructed with a core material that provides high current overload capabilities and low radiated noise. It also features a low core loss, allowing the device to be used in high frequency circuits. The device also has an integrated ferrite shield that eliminates external electric field radiation.

The device’s magnetically shielded construction reduces the size of the device as it eliminates the need for an extra line filter. This reduces the cost of the part as well as the board space it requires. The LB2518T100K also features an 8-ohm leaded inductor, allowing for direct connection to a circuit board. The device is rated for an operating frequency from 10kHz to 500kHz, with a maximum current of 2.2A.

The LB2518T100K has a low DC resistance and low parasitic reactance. This enables the device to be operated with low power consumption. The high Q factor and low inductance make it suitable for switching power supply circuits, as well as high frequency filter networks. It is also suitable for use in synchronous rectifiers.

The working principle of the LB2518T100K is based on the fact that an AC current passing through a coil of wire generates and stores a magnetic field. When this current is switched off, the stored magnetic field of the coil induces a voltage in the coil. This voltage can be used to power a load or to provide a reference voltage in a circuit.

In addition to its fixed inductor status, the LB2518T100K also supports AC current sensing, due to its low DC resistance rating. By connecting the device in series with a load, the current draw of the load can be monitored, allowing for the detection of faults and over-current situations.

The LB2518T100K is an ideal device for use in a wide variety of applications. Its low profile design makes it suitable for use in high density circuits, while its high current overload capability and strong magnetic field shielding make it suitable for many different types of circuits. Its low inductance and low parasitic reactance make it ideal for power supply applications, while its current sensing capability makes it an ideal choice for fault detection and over-current protection.
