COMMON MODE
Common Mode Choke Arrays
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
Features:
·Surface mount design ·The most economical common mode filter available for filtering groups of signals ·Can be used as multiturn 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
Test Specifications:
·HP4396A (100KHz - 1.8 GHz) or HP8753 (to 6 GHz) Network/Spectrum Analyzer ·HP43961A Impedance Test Kit ·HP16192A Test
Fixture or Inter-Continental Microwave custom fixtures ·HP16200A DC Bias Adapter ·Philips PM2811 DC Power Supply ·Ambient
Temperature 23.5oC + 2o ·Bandwidth 3 kHz ·Sweep Time 423 ms ·Impedance is rated at + 25% @100MHz ·Board level components
are rated up to a maximum of 75 volts ·Maximum current ratings are determined by testing to a maximum temperature rise of 40oC
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).
