Fixed inductors are beneficial for designing circuits in which current needs to be maintained and kept stable. This type of component works by controlling and regulating the electrical current flowing within the circuit. As such, these types of circuits are highly suitable for applications which require steady current, including power supplies, switching supplies and voltage converters. SC30R39KT is a common type of fixed inductor used in many electrical designs.

The SC30R39KT can be applied in applications where high current stability and low EMI are important. It offers high stability of current and very low noise emissions. Its main design features include two identical pairs of coils wound in opposite directions, with each pair connected to opposing pins. This allows the current induced in one pair of coils to cancel out the current induced in the other pair, resulting in a perfectly balanced and stable output current.

In terms of construction, the SC30R39KT consists of a polycarbonate core, four separate terminals and two layers of enameled wire overlaid on one another. The design of this type of inductor ensures that the current induced in one pair of coils is equal and opposite. This feature helps to stabilize the output current, resulting in improved reliability and reduced emissions.

The main principle of operation is that, when an electrical current is applied to the SC30R39KT, it creates a magnetic field around the core. This magnetic field induces a current in the coils, which is equal and opposite to the current applied. This equal and opposite current opposes the applied current, acting as an inductor to regulate the current level.

In summary, the SC30R39KT is a fixed inductor designed for applications requiring current stability and low EMI. It is constructed with two identical pairs of coils wound in opposite directions, and features a polycarbonate core and four separate terminals. Its main principle of operation is that it creates a stable output current by opposing the applied current, thanks to the induction of a current in the coils equal and opposite to the applied current.
