Common Mode Choke Arrays
COMMON MODE
Features:
Steward ‘s
multi-line common mode power/data array filters provide the most
economical EMI filtering available for common mode noise. These ferrite
surface mount filters provide EMI suppression for groups of conductors like
power traces and high speed input/output circuitry (including network and
storage subsystems). Steward’s common mode choke arrays exhibit high
frequency impedance essentially independent of low frequency AC or DC bias
current.
Protected by the following US Patent : 5,455,552
·Surface
mount design
·The
most economical common mode filter available for filtering groups of signals
·Can
be used as multi-
turn device to multiply impedance
·With
two turns, over 1000 ohms impedance at 100 MHz
·Will
fit behind an RJ45 jack
·High
continuous operating current carrying capability
·4,
6 or 8 line parts
·Parts
available in broad band and high frequency
materials
Applications:
·Cost
sensitive designs (no need for an expensive filtered connector)
·Filtering
DC power on PC boards, especially in applications of
greater than 3.0 amperes
·Filtering
common mode EMI on high speed differential lines such as network and SCSI subsystems
·Low
normal mode distortion provides excellent response in telecom applications

with continuous operating current. Part performance is shown with curves for Common, Open and Normal Mode Impedances
measured along two conductors.
Common Mode
Impedance is the impedance of EMI noise conducted in the same direction along
two conductors.
Open Circuit
Impedance is the impedance measured across a single leg of the common mode choke.
Normal Mode
Impedance is the total impedance to the differential circuit (both out and back).
