Fixed inductors refer to electrical components with special coil shapes that utilize induction principles to provide a reliable and consistent electric current and voltage. The SC73B-271 fixed inductor is a product from Bourns Inc., a global leader in the production of high-performance, precision electronic components. This particular inductor is mainly used in the consumer market, such as in DVD players, cell phones, and other consumer analogue electronics.

The SC73B-271 performs quite differently from the traditional fixed inductive components. Instead of having an inductive core, the inductor\'s entire body is composed of an exceptionally thickened magnetic slush layer, which acts as the inductor\'s core. This slush layer is composed of an iron-titolium ferrite powder mix made from zinc, which is mixed into a paste and then vacuum molded into a compact, thin disk shape, which provides the inductor core\'s high-efficiency performance.

One key feature that sets the SC73B-271 apart from other inductors is its advanced permeability control. Its high permeability reduces series inductance by one-third compared to other traditional fixed inductors, while providing superior inductance and current ratings. Additionally, its integrated bias winding offers greater operating frequency and flux capabilities, enabling higher inductance and current ratings at higher frequencies.

The SC73B-271 features two distinct winding materials. The first material, referred to as the core material, is a cross-linked polyphenylene sulfide (PPS) insulation. This material not only ensures excellent insulation from electrical failures or surges, but also improvements in noise reduction and temperature stability. The second material is a conventional, insulated, enameled wire which provides the inductor\'s conductivity. This layer offers increased frequency range and improved distorting power ratings when compared with standard wire winding methods.

The SC73B-271 fixed inductor also features a low profile design, measuring only 2.5mm in diameter, with a maximum height of 3.2mm. This small size enables easier installation and saves valuable space in electronic devices where space is limited. Furthermore, the overall design offers lower core losses, which allows the inductor to generate less heat and minimize power consumption.

The SC73B-271 fixed inductor offers improved stability over traditional inductor designs, helping to ensure better performance and reliability. The combination of its advanced permeability and winding materials provide superior current and voltage capabilities, making it an ideal choice for consumer electronics. Additionally, its small size and low power consumption make it a great option for applications with limited space and power.
