PLM3216K Series
The PLM3216K SMT common mode choke uses Murata’s
unique monolithic technology process. High impedance
characteristics provide excellent noise suppression in a
small, compact size (3.2 x 1.6 x 1.15mm) to remove
common mode noise.
FEATURES
I Prevents common mode noise on signal lines in data
communication equipment or digital equipment.
I Low leakage flux due to its full monolithic structure
I Suitable for auto-placement
APPLICATIONS
Prevention of common mode noise on signal lines in
personal computers, computer peripheral equipment,
facsimiles, digital telephones, etc.
