PFN2028 Datasheet, PDF (1/1 Pages) Sumida Corporation – EMC & PFC Choke Coil

EMC & PFC Choke Coil <Pin Type: PFN Series>
Type: PFN2028
◆ Product Description
・￠26.0mm×31.0mm.MAX.
・Custom design is available.
◆ Feature
・Iron dust core is used to realize better DC saturation characteristics and
higher noise absorption effect and less leakage magnetic flux by using toroidal core.
・Ideally used as EMI choke in power line and signal line or switching power supply for noise
prevention.
・Ideally used as Power Factor Correction choke.
・RoHS Compliance.
