EMI-RFI Filters
LF Metal Box Single-Phase & Three-Phase Filters
Overview
The KEMET LF metal box filters cover single-phase
or three-phase requirements with a wide variety of
characteristics. These filters are optimized for conduction
noise. Their input/output terminals are screw type or
lead wire type.
