Fixed Inductors

Fixed inductors are specialized electrical components used to store or release electrical energy. They come in all shapes and sizes, from tiny microinductors to large power inductors. The SP1210R-393G is a type of fixed inductor manufactured by Würth Electronics. This particular inductor is designed for use in switch mode power supplies and low noise DC/DC converters.

The SP1210R-393G is a low profile planar inductor with a flat top profile. It features a shielded construction which helps reduce EMI, and it has an operating temperature range of -40°C to +105°C. The inductor offers excellent thermal performance, with very low thermal resistance. In addition, the flat top profile allows for easy mounting and minimal board space requirements.

In terms of design, the SP1210R-393G is composed of a ferrite core, a coil of copper wire, and two feet. The ferrite core provides the inductance, while the coil of copper wire acts as the primary inductance and stores and releases electrical energy. The two feet are connected to the terminal pins, allowing current to flow through the device.

In terms of its application field, the SP1210R-393G is designed for use in switch mode power supplies, low noise DC/DC converters, and other electronic applications. Its primary uses include providing temperature-stable, low inductance for converting main power supplies to lower voltage levels, as well as filtering large signals and providing stability in the feedback loop. It is also often used in mobile communication equipment and automotive applications due to its low profile and excellent thermal characteristics.

In terms of its working principle, the SP1210R-393G operates on the principles of electromagnetic induction. This inductor generates an alternating magnetic field when a current passes through its coil of copper wire. This magnetic field induces a voltage across the two feet, which can then be used to drive a load and to transfer energy to and from the device. The device also acts as a filter, blocking any unwanted electrical noise or interference in the system.

In summary, the SP1210R-393G is a type of fixed inductor manufactured by Würth Electronics. It is designed for use in switch mode power supplies, low noise DC/DC converters, and other electronic applications. Its primary uses include providing temperature-stable, low inductance for converting main power supplies to lower voltage levels, as well as filtering large signals and providing stability in the feedback loop. The SP1210R-393G operates on the principles of electromagnetic induction, generating an alternating magnetic field which induces a voltage and transfers energy to and from the device.
