Fixed inductors are electrical components used to store electric charge in moderate electric field, resist the change of current and manage power supply ripple current. They typically take the form of a wire carrying a coil-like shape on a circuit board or other non-conductive base. The SC32-6R8 is an example of a fixed inductor component, largely used in AC and DC power supplies and motion control applications. This article will explain further the application field and working principle of the SC32-6R8.

The SC32-6R8 is a high-performance Common Mode EMI Choke that can be effectively used in broadband noise reduction and DC power line noise suppression. It is designed with a U-shaped, ferrite core structure with two bobbins, that have a cross-sectional area of 8.1mm, allowing for high-frequency suppression capability. This SC32-6R8 inductor offers high grounding impedance at typical and maximum rated high temperatures. With a high inductance and rated current of about 160uH (at 100kHz) and 6.8A (at 70?C), its inductance stability over varying temperature and current levels is excellent. Its housing is suitable for use in applications with limited installation space, with an outside diameter of about 28.5mm and a height of about 33.1mm.

The SC32-6R8 is usually designed for medium and high-frequency AC and DC power supplies in the power electronics market, such as solar controllers, wind power systems, motor drives and frequency converters. It is also used in motor controllers for various appliances with current rating as low as 6.8A and energy efficiency up to 97%. In AC and DC power supplies, it is used to filter out Noctilucent. In motion control systems, it is used to reduce the surge current output, enhance the system’s running stability and improve the motor’s efficiency.

In terms of the working principle of the SC32-6R8, it has an inductance value of 160uH. This inductance value is also known as the “self-inductance” of the component. This self-inductance works by creating an electric field that opposes the rate of change of current passing through it. When a current is applied to the SC32-6R8, an opposing voltage is created across the wire coiled on the magnet core. This opposing voltage works by restricting the current flow, and is known as inductor “back EMF”. The higher the inductance of the component, the more resistance it has, increasing the back EMF and restricting the current flow.

The working of the SC32-6R8 can be quickly summarized. It acts as a filter for both AC and DC power supplies, dampening the ripple current typical to power supplies. It also uses inductor back EMF to restrict the current flow, making it a highly beneficial component in motion control systems.

In summary, the SC32-6R8 is a highly efficient fixed inductor component that can be effectively used in broadband noise reduction and DC power line noise suppression, while also providing protection from Noctilucent in AC and DC power supplies. Its high inductance and rated current makes it suitable for use in medium and high-frequency power supplies, motor drives, frequency converters, and motion control systems. Its working principle relies on the creation of an electric field and inductor back EMF to restrict current flow, making it a highly beneficial component in a wide range of applications.
