Data and signal line chokes
SIMDAD 1812, common-mode chokes
B82789C0/S0
Rated voltage 42 V AC/80 V DC
Rated inductance 11 NH to 100 NH
Rated current 150 mA to 300 mA
Construction
■ Current-compensated double choke
■ Ferrite I core
■ Winding: enamel copper wire
■ Winding welded to terminals
■ Bifilar winding (B82789C0…)
■ Sector winding (B82789S0…)
Features
■ Temperature range up to 150 °C (B82789C0/S0*H)
■ Suitable for lead-free reflow soldering as referenced in JEDEC J-STD 020C
■ 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.
Applications
■ Automotive applications, e.g. CAN and FlexRay bus
■ Industrial field bus systems
■ Line cards for telecom
