Common Mode Chokes for High Speed Signal Filtering (TCPWCH-1210HS/2012HS)
Introduction (TCPWCH-1210HS/2012HS)
In the electronics environment seen by today there are numerous sources of radio frequency interference (RFI) and electromagnetic interference (EMI). This is due in large component to the increased use of RF technology. These types of interference result in the need for common mode filtering in applications utilizing differential interfaces. Token common mode chokes help maintain the integrity of high speed communications and may be necessary for conformance with international regulatory standards.
Token (TCPWCH-1210HS/2012HS) Series SMD Common Mode Choke Coils are for high-speed and ultra-high-speed differential signal lines such as LVDS, IEEE1394//FireWire, USB, etc. The chip type (TCPWCH-1210HS/2012HS) series provides EMI suppression in case sizes 0504, and 0805. The SMD Common Mode Chokes are useful in a number of applications, such as power supply units, cellular baseband, audio circuit, CPU, interface, display panel, remote controllers, and inverters.
Updated News! Token has expanded its (TCPWCH-1210HS/2012HS) series common mode chokes to include the TCPWCH-1210HS-900TR and TCPWCH-2012HS-900TR, designed to address the unique noise issues of higher frequencies of USB 3.0 (SuperSpeed) devices. The Token TCPWCH-1210HS/2012HS-900TR, matches the characteristic impedance of the 90Ω USB3.0 standard. The common mode chokes utilize winding technology using EMI Suppression Ferrite cores processes to successfully boost the cut-off frequency in the transmission characteristics of the choke coils from the cut-off frequency featured by previous series to a higher, enabling SuperSpeed signals to be transmitted.
All (TCPWCH) series comes a wide variety of options to meet your needs with halogen free and feature RoHS Directive. Token is able to customize and manufacture your request.
