Conformity to RoHS Directive
Differential Mode Choke Coils(RADIAL)
For Signal Line and Power Line, Standard Type Non-molded
SF-T Series
FEATURES
• The SF series chokes feature cores with high saturation
magnetic flux density. They thereby provide an effective means
of combating pluse EMC.
• By using an advanced amorphous metal alloy core, the SF
series are able to provide line noise attenuation performance
equivalent to conventional ferrite-based chokes but with far more
compact dimensions and fewer coil turns. They can thus be
implemented in high-density circuit configurations to comply with
various EMC-related regulations.
• The products contain no lead and also support lead-free
soldering.
