Fixed inductors are an essential basic component of many soft-start motors, power stages, and switched-mode power supplies. The S1210R-681H is a fixed inductor designed for use in such devices. It is a 12 turn, 0.5A maximum current rated large-sized ferrite core inductor.

The dimensions of the S1210R-681H are 28.6mm (length) x 10.2mm (width) x 14.5mm (height). The weight of this unit is 15g. This inductor has a rated tolerance of ±20%. The operating temperature range is -40 to +105oC.

The S1210R-681H fixed inductor is suitable for use in applications such as DC-DC converters, switch mode power supplies, ceramic resonators, and other applications requiring high power inductors. It is also suitable for use in high voltage and high frequency applications such as motor control, ballast and light dimming, and so forth. The inductor offers efficient operation with high thermal stability.

A key feature of the S1210R-681H is its ability to provide high-frequency characteristics without compromising on insulation or reliability. This is suitable for both high-temperature and high-power applications. The unit also features overload protection and over-temperature protection, making it suitable for a wide range of applications.

The working principle of the S1210R-681H fixed inductor is simple. When a voltage is applied to the inductor, a magnetic field is created that induces a current in the inductor\'s windings. This current passes through the magnetically coupled air gap, creating a back-EMF. This back-EMF opposes the applied voltage and restricts the current flowing through the inductor. This behavior produces a high frequency characteristic and makes the inductor suitable for use in high-frequency applications.

In conclusion, the S1210R-681H is a large-sized ferrite core inductor suitable for use in applications such as DC-DC converters, switch mode power supplies, ceramic resonators, and other applications requiring high power inductors. It offers an efficient operation with high thermal stability and overload and over-temperature protection. The simplified working principle is based on creating a back-EMF by passing a current through a magnetically coupled air gap, which is then opposed to the applied voltage. These characteristics make the S1210R-681H a suitable device for use in a variety of applications and it is therefore classified as a fixed inductor.
