Common Mode Chokes are a type of three-terminal electronic components that are mainly used for electromagnetic interference (EMI) and radio frequency interference (RFI) suppression. Typical applications for common-mode chokes include data lines, power cords and DC power lines. The UU9LFHNP-HB471 is a specific type of common-mode choke that provides excellent EMI and RFI protection across a wide frequency range from 6 MHz up to 400 MHz, with a typical insertion loss of -29 dB at 400 MHz.

The UU9LFHNP-HB471 common-mode choke is designed with three terminals, a pair of Parallel Synchronous Inductors (PSI), two DC Current Sensors (DCS) and an EMI Filter Core block. The PSI section contains two air core inductors placed in parallel. This allows the inductors to couple with each other, and current to flow from one inductor to the other in either direction. The synchronous designs of the inductors also provide excellent EMI protection across a wide range of frequencies. The DCS section contains two Hall-effect current sensors, which measure the current flowing through the inductors. The Hall-effect sensors also provide a high degree of accuracy and linearity, so that the current can be precisely measured and accurately determined. The EMI filter core block is used to reduce EMI noise generated by the inductors and DCS sensors, so that it does not affect the performance of the choke.

The UU9LFHNP-HB471 common-mode choke is designed to provide optimal EMI and RFI protection. It is constructed with UL 94V-0 flame-retardant materials to ensure long-term performance and durability. The choke has a maximum operating temperature of 100°C, and an operating frequency range of 6 MHz up to 400 MHz. The typical insertion loss of -29 dB makes it ideal for applications that require high levels of EMI and RFI protection, such as data lines, power cords and DC power lines.

In summary, the UU9LFHNP-HB471 is a common-mode choke that provides excellent EMI and RFI protection across a wide frequency range. It is designed with three terminals, two parallel synchronous inductors, two DC current sensors and an EMI filter core block, and constructed with UL 94V-0 flame-retardant materials for durability. It has a maximum operating temperature of 100°C, and a typical insertion loss of -29 dB. The UU9LFHNP-HB471 is suitable for a wide range of applications, such as data lines, power cords and DC power lines.
