DATASHEET Three-Stage Filters FN 352Z
Multi-stage EMI Filter
Rated currents from 6 to 30 A Approvals
Surge pulse protection up to 2 kA
Solder or screw connection
Features and benefits
FN 352Z series is developed to meet high filter
attenuation requirements by using multi-stage filter
design
Additional high surge pulse voltage protection up
to 2 kA is integrated to protect sensitive equipment
Choosing FN 352Z product line brings you the rapid
availability of a standard filter associated with the
necessary safety acceptances
Standard filters are a practical solution helping you
to pass EMI system approval in a short time
Exceptional conducted attenuation performance,
based on multi-stage design and chokes with high
saturation resistance and excellent thermal behavior
