DC Line Filters
Normal Mode for Signal Line,
Through-Hole Type, Bead Lead Type Series
Overview
The KEMET lead type beads intended for normal mode
noise suppression have a wide variety of characteristics.
These through-hole beads are designed with our
proprietary ferrite material and are suitable for noise
countermeasure in DC signal line circuits.

• Audio-visual equipment
• Office automation equipment
• Digital appliances
• Home appliances
• Power supplies
Benefits
• Proprietary Nickel-Zinc (Ni-Zn) ferrite core
• High loss
• High reliability
• Operating temperature range from −20°C to +70°C
• RoHS Compliant
