Fixed inductors, also known as chokes, are passive components used to control current in an electronic system without interrupting it or dissipating power. These inductors are also used to step up or reduce the voltage in power supplies, AC circuits, and other systems. The SC32-681 is a type of fixed inductor manufactured by Sumida Corporation, which is a global provider of electronic and magnetic components and assemblies.

The SC32-681 inductor uses the parallel-line technology of Sumida\'s Schaffner clip-lock series. It is constructed of high-grade powder-core rods that are permeated with uniform and reliable air-gaps. These rods are encased in an attractive and rugged aluminum can design, providing effective protection against vibration and shock. This type of inductor is designed to meet the stringent requirements of automotive applications such as dynamic motor control, non-isolated power supplies, and automotive infotainment systems. The inductor features a low stress coil design for improved linearity and performance over standard designs.

The SC32-681 inductor has a maximum rated current of 1.2A, an inductance range of 0.1μH to 68μH, and a temperature range of -40°C to +125°C. It also has a maximum DC resistance of 0.9Ω and a saturation current of 1.6A. The device is available in a 10x10x7mm package and can handle up to a 10A peak current. Sumida provides the SC32-681 inductor with various options such as leaded, lead-free, and with integrated EMI shields.

The working principle of the SC32-681 inductor is based on electromagnetic induction. The device consists of an insulated copper coil wound around a ferromagnetic core. When a current passes through the wire, it generates a magnetic field around it, which in turn induces an electromotive force in the self-inductance coil. This induces a current to flow through the coil, which is proportional to the rate of change of the main current. Inductors are used in a variety of applications because they can limit the rate of current change, control AC power, and store energy.

The SC32-681 inductor has a wide range of applications in automotive, aerospace, and medical devices. It can be used in dynamic motor control circuits, power supply units, anti-lock braking systems, Audio streaming systems, Satellite navigation systems, Medical implants, Power management systems, Audio amplifiers, and Motor control boards. The device is a reliable and efficient source of magnetic control, allowing users to optimize their circuits for improved performance and reliability.

In conclusion, the SC32-681 inductor is a reliable, cost-effective, and efficient device for a variety of applications. It is a high-performance device with excellent linearity and a long service life. Sumida provides these inductors in various performance options and packages, allowing designers to select the right inductor for their application.
