Working Principle

The SC4020FH-4R7 operates according to the fundamentals of inductive components, in which a changing magnetic field induces a voltage into a circuit. Specifically, the device is composed of four shield cores and four DC resistors. The shield cores act as a barrier to reduce EMI/RFI noise, as well as provide high inductive values. The shield cores are also used to induce the desired voltage within a specific frequency range, and to induce precise step-by-step current control. On the other hand, the four DC resistors are used to minimize harmonic distortion or interference from the magnetic field, providing low-current applications with more stable operation.

The SC4020FH-4R7 is designed to be highly efficient in terms of energy consumption and electromagnetic radiation. It features a low leakage inductance, allowing it to reduce power line noise and provide efficient filtering. Additionally, its high bias current capability allows the device to maintain higher inductance values when supplied with higher DC voltages. This makes it an ideal component for applications such as AC/DC converters, magnetically-coupled circuits, and other power line filter designs.

Conclusion

The SC4020FH-4R7 is a four-rod, four-shield core, and four-DC resistor device designed for a wide range of power line applications. It offers excellent noise and EMI/RFI filtering characteristics, low power consumption, and superior power density. The shield cores, leakage inductance, and DC bias current allow the device to provide precision current control and stable resistive loads for high-current applications. Additionally, its small size allows it to fit in almost any application design.
