■
■
■
Temperature range up to +150 °C (B82789C0/S0*H)
Suitable for lead-free reflow soldering as referenced in JEDEC J-STD 020D
For gold-plated terminals conductive adhesion possible
Qualified to AEC-Q200
RoHS-compatible
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
R
) 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.
