Function
B82789C0:
Suppression of asymmetrical interference coupled in on lines,
whereas data signals up to some MHz can pass unaffectedly.
B82789S0:
Suppression of asymmetrical (by L ) and symmetrical interference (by L )
R 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.
