Fixed Inductors

Fixed inductors are passive electronic components that incorporate a coil, magnetic core and other components that can be used in applications such as frequency filters, oscillators and transformers. While passive components are always found in electronic circuits, fixed inductors can be optimized to provide a range of specific functions.The SP1812R-274G is a type of fixed inductor from Sumida, created to meet specific electrical requirements in a variety of electronics. This inductor is a surface-mount device created for use in power supply designs and other applications that require a high level of reliability in a small form factor.

Application Field

The SP1812R-274G is a fixed inductor designed for use in small applications that require a high degree of efficiency and consistent performance. These inductors are suitable for low-current to moderate-current devices, such as power supplies, LED drivers, switching power supplies, DC/DC converters, and wide-range input devices. The surface mount inductor can also be used in automated test and measurement equipment, as well as a wide range of other applications.

Working Principle

A fixed inductor is made up of a coil, which is designed to produce and maintain a magnetic field. When current flows through the coil, it produces a magnetic field which stores energy and generates opposing forces. These forces are referred to as ‘self-induction’ and can be used for various functions including frequency filters, oscillators, and transformers.The SP1812R-274G fixed inductor is a high-precision surface mount device that incorporates a copper-wire coil, which is wound on an iron-cobalt alloy core. This core provides a high-quality magnetic flux and minimizes any resistance that may exist in the circuit. The inductor also includes an integrated shield, or enclosure, to minimise interference from external sources.The primary function of the SP1812R-274G is to convert alternating current (AC) into direct current (DC). This is done by controlling the amount of current flow through the coil, which changes the magnetic field and frequency of the AC. This creates a DC voltage waveform with improved energy efficiency and performance.The SP1812R-274G is designed to be used in a variety of high-precision, low-current to moderate-current applications. Its high-precision coil and core incorporate an induction range between 1000 and 6000 nH, a quality factor (Q) between 10 and 25, and a DC resistance (Der) from 5-75 milliohms.

Conclusion

The SP1812R-274G is a type of fixed inductor from Sumida, designed to meet specific requirements in a variety of electronics. This surface-mount device is designed for low-current to moderate-current applications, including LED drivers, switching power supplies, DC/DC converters, and wide-range input devices. Its high-precision copper-wire coil is wound on an iron-cobalt alloy core, which provides a high-quality magnetic flux and minimizes any resistance that may exist in the circuit. The SP1812R-274G can be used to convert AC into DC, providing improved energy efficiency and performance with an induction range between 1000 and 6000 nH, a Q factor between 10 and 25, and a Der resistance from 5-75 mOhms.
