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.
