B82789N Datasheet, PDF (1/6 Pages) EPCOS – Chokes for data and signal lines

Chokes for data and signal lines
I core choke, EIA 1812
B82789*N
Rated voltage 42 VAC/80 VDC
Rated current 150 to 300 mA
Rated inductance 11 to 100 µH
Construction
■ Current-compensated double choke with ferrite I core
■ Bifilar winding (B82789C0…)
■ Sector winding (B82789S0…)
Features
■ Suitable for reflow soldering
■ For gold-plated terminals conductive adhesion possible
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_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
Applications
■ Automotive applications, e.g. CAN bus
■ Industrial automation
■ Telecommunications
Terminals
Two versions: Gold plated and lead-free tinned
Marking
Marking on component:
Manufacturer, bifilar or sector winding (coded), L value (in nH),
