B82796C0/S0
Current-compensated ring core double choke
Ferrite core
Polycarbonate case (UL 94 V-0)
Silicone potting
Bifilar winding (B82796C0)
Sector winding (B82796S0)
Features
■
Suitable for automatic insertion
■
Suitable for wave soldering
■
RoHS-compatible
Applications
■
B82796C0:
Suppression of asymmetrical interference coupled in on lines,
whereas data signals up to some MHz can pass unaffectedly.
■
B82796S0:
Suppression of asymmetrical and symmetrical interference
coupled in on lines. The high-frequency portions of the symmetrical
data signal are decreased so far that EMC problems can be
significantly reduced.
