Construction
■
Current-compensated ring core double choke
B82799
with ferrite core
■
Bifilar winding (B82799-C…)
■
Sector winding (B82799-S…)
Features
■
■
■
■
High performance
Case flame-retardant as per UL 94 V-0
Suitable for reflow soldering and conductive adhesion
Operation up to 150°C (for
L

H)
Applications
■
B82799-C:
Suppression of asymmetrical interference coupled in on lines,
whereas data signals up to some MHz can pass unaffectedly
■
B82799-S:
Suppression of asymmetrical (by
L
R
) and symmetrical
interference (by
L
S
) coupled in on lines. The high-frequency
portions of the symmetrical data signal are decreased so far
that EMC problems can be significantly reduced
