ALFT-04-1

Common mode chokes are devices that are used to remove unwanted electromagnetic interference within an electronic system. ALFT-04-1 is an example of a common mode choke, specifically designed for the field of telecommunications. The ALFT-04-1 is an advanced, ultra-low impedance common mode inductor, with a specified common mode impedance of less than one ohm.

The ALFT-04-1 has been designed to meet the requirements of the communications industry. It utilizes a sophisticated four-hole ferrite core which provides high common-mode inductance and a superior common mode impedance with a low DCR compared to similar single hole designs. As such, the ALFT-04-1 can provide excellent high frequency noise suppression up to several MHz.

The working principle of the ALFT-04-1 is straight-forward. In an electronic system, unwanted electromagnetic interference can occur within the DC power lines, as well as within the signal lines. This noise can degrade system performance and lead to unreliable operation of the system. By installing a common mode choke, such as the ALFT-04-1, on the various DC and signal lines of the system, it is possible to reduce or eliminate this interference.

The ALFT-04-1 operates by using its high-inductance core to suppress high-frequency interference, while also providing excellent suppression of low-frequency interference. The common mode inductance of the ALFT-04-1 allows it to block the transfer of interference between different signals. It is designed to have a low DCR, which allows it to absorb even the smallest signal current interference while preventing excessive power dissipation.

The ALFT-04-1 also offers superior noise suppression capabilities due to its flat frequency response. This is achieved through its lamination design, which ensures that the frequency response remains constant regardless of the common mode current passing through the device. This makes it an ideal choice for suppressing broadband interference, and it can be used in both AC and DC applications.

In conclusion, the ALFT-04-1 application field and working principle is that of a common mode choke. It is designed to efficiently suppress and eliminate interference on DC power lines and signal lines, resulting in improved system performance and reliability. The ALFT-04-1 utilizes a sophisticated four-hole ferrite core to provide high-inductance, flat frequency response, and superior common mode impedance, resulting in excellent noise suppression up to several MHz. It is an ideal choice for suppressing low-frequency interference, as well as broadband interference.
