Fixed Inductors

Inductors are electronic components that store energy in the form of a magnetic field. Fixed inductors are components with a single inductance value that cannot be adjusted. One such fixed inductor is the SD3112-151-R. This component is widely used in various applications, from power supply filters and antenna coils to motor control drive circuits.

SD3112-151-R Specifications

The SD3112-151-R has a number of impressive technical specifications, including a rated current of 1.5A, an inductance range of 150mH ± 20%, and a saturation current of 4A. It also has a maximum DC resistance of 0.20 ohms, an operating temperature range of -40°C to +105°C, and a storage temperature range of -55°C to +125°C.

Application Fields

The SD3112-151-R is used for a variety of applications, most notably in power supplies, such as dc-dc converters, inverters, transformers, and uninterruptible power supplies (UPS). It can also be used in low dropout (LDO) regulators, alternating current (AC) to direct current (DC) converters, and other motor control equipment. Other possible applications include radio frequency (RF) filters, antenna coils, and digital signal processing (DSP) filters.

Working Principle

The SD3112-151-R works by converting electrical energy into magnetic energy and storing it as a flux field around its core. When current passes through its coils, the component generates a magnetic field proportional to the current. This magnetic field then induces a voltage in its own windings, which is proportional to the rate of change of current. The combination of the magnetic field generated by the current and this induced voltage is what gives the component its inductance.

Conclusion

The SD3112-151-R is a fixed inductor which is widely used in a variety of applications, such as power supplies, low dropout regulators, motor control drive circuits, and RF filters. It works by converting electrical energy into magnetic energy, and storing it as a flux field around its core. This magnetic field induces a voltage in its own windings, and this inductance is what makes the component so useful in a variety of applications.
