Common mode chokes are electrical components used to reduce electromagnetic interference (EMI) in signal lines. They are similar to ferrite beads, but are usually designed for higher frequency applications. The EXC-14CX400U is a common mode choke designed for Ethernet and synchronous optical networking (SONET) applications.
The EXC-14CX400U features a center-tapped design with two cores of differing inductance values. The single-ended coil winding structure allows for a wide range of application fields, including Ethernet, InfiniBand, sync-optical networks, radio controllers, and cell phones. The EXC-14CX400U also features a low DCR rating of 0.050Ω, which helps minimize power dissipation. The device also offers excellent common mode and different mode attenuation characteristics, which helps reduce EMI and improve signal integrity.
The working principle of the EXC-14CX400U is quite simple. When connected to a signal line, the differential mode current will flow through the winding and both cores of the choke. The differential mode current is primarily composed of fundamental frequency components. The common mode current will flow through the winding but will be blocked by one of the cores. This core will induce a magnetic field that will oppose the flow of the common mode current, thus, reducing the EMI.
The EXC-14CX400U is also designed to be highly temperature stable. The choke has an operating temperature range of -40°C to +85°C. The choke also features a low thermal coefficient of inductance that helps maintain high signal integrity over temperature extremes.
Overall, the EXC-14CX400U common mode choke is designed to provide excellent common-mode and different-mode attenuation, as well as temperature stability and low DCR. The device is ideally suited for applications in Ethernet, InfiniBand, sync-optical networks, radio controllers, and cell phones. Its simple configuration and excellent performance make it a great choice for designers looking for reliable EMI suppression.
