B82790C0/S0
Current-compensated ring core double choke
Ferrite core
PPS case (UL 94 V-0)
Bifilar winding (B82790C0)
Sector winding (B82790S0)
Features
■
Suitable for reflow soldering
■
Qualified to AEC-Q200
■
RoHS-compatible
Function
■
B82790C0:
Suppression of asymmetrical interference coupled in on lines,
whereas data signals up to some MHz can pass unaffectedly.
■
B82790S0:
Suppression of asymmetrical and symmetrical interference (by L
stray
)
coupled in on lines. The high-frequency portions of the symmetrical
data signal are decreased so far that EMC problems can be significantly reduced.
