PART NUMBER SYSTEM EXAMPLE
See Page 41 for Equivalent Circuit Examples. Common Mode Choke Master List on Pages 42 & 43.
Surface Mount Common Mode Chip Beads offer low profile, compact filtering of common mode noise (EMI) for
applications carrying up to 10 amps of continuous current. The advanced monolithic construction provides low profiles
with a package size as small as EIA 1812, perfect for filtering power supply circuits in notebook computers, power
adapters, and other mobile products. Servers, workstations, and consumer products benefit as the compact packages
allow increased component density in high current circuits. All versions are lead-free and RoHS compliant. Stable
performance under load.
Parts have no polarity.
