Fixed inductors are electrical components that are designed to resist changes in the flow of electric current through them. The LGJ12575TS-2R7N7R0-H is a type of fixed inductor and is used in a variety of applications.

This device is an axial-leaded, 4-position SMT inductor that utilizes a multilayer toroidal core, with a wide inductance range of 0.10 to 10 mH and low DC resistance range of 0.20 to 1.50 ohm. Additionally, this fixed inductor has held an outstanding temperature stability over the entire operating temperature range.

One of the most common applications of a fixed inductor, such as the LGJ12575TS-2R7N7R0-H, is in the power supply unit of electronic equipment. The fixed inductor is used to reduce the high-frequency noise generated by the switching power supply. To accomplish this the inductor filters the voltage ripple emitted by the switching transistors.

The principle of operation for this type of inductor is based on Faraday’s law of induction, which states that a moving charge creates a changing magnetic field, which in turn induces a voltage in a nearby conductor. A fixed inductor utilizes this effect to help regulate the current passing through it, allowing for more efficient use of current.

The LGJ12575TS-2R7N7R0-H in particular, works to reduce the amount of required board space and power dissipation. It does this through a combination of several factors. The first of these is the close proximity of the magnets and coil winding. This produces a high magnetic flux density, which increases the inductance value with a reduced amount of material. The coil pattern is also designed so that the magnetic field circulates within the core, which further reduces the amount of material needed. The size and weight of the device are also reduced by utilizing a ceramic ferrite core.

In addition to providing a shortened board area and low power dissipation, this type of inductor also offers several other benefits. It has an operating temperature range of -40° C to +125° C, which makes it suitable for use in harsh environments. Additionally, it provides excellent temperature stability, as well as very low DCR and ESR values.

The LGJ12575TS-2R7N7R0-H is a high-quality, reliable fixed inductor that provides several benefits for a variety of applications. The device offers a mix of reduced board size, high magnetic flux density, power dissipation and excellent temperature stability. These factors make the LGJ12575TS-2R7N7R0-H an ideal choice for applications involving power supplies, filters, flyback converters or any sort of switch-mode power supply.
