EMC MORMAL MODE CHOKE COIL <Pin Type: PFN Series>
Type: PFN0818
â Product Description
ã»ï¿ 19.0mmÃ9.5mm.MAX.
ã»Inductance range: 21μHï½60μH; Rated current range:2.6Aï½3.7A
ã»In addition to the standard versions of parameters shown here,
custom designs are available to meet your exact requirements.
â Feature
ã»Iron dust core is used to realize better DC saturation characteristics and higher noise absorption
effect and less leakage magnetic flux and core groan by using troidal core.
ã»Ideally used in EMI for power line and signal line for various kinds of electric equipment as line
filters for input or switching power supply, noise prevention in thyristor such as SCR and triac, for
DC spike noise suppression,immunity for automotive related electric device,for home electric
device with microcomputer.
ã»Can also be used as power factor correction chokes.
ã»RoHs Compliance
