FEATURES
TYPICAL CHARACTERISTICS OF SF CORE
µi[300kHz]

• The SF series chokes feature cores with high saturation mag-
netic 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.
