EPCOS B82789C0113N001 Chokes for data and signal line Datasheet

Chokes for data and signal lines
B82789*N
I core choke, EIA 1812
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 LR) and symmetrical interference (by LS)
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),
date of manufacture (coded)
Minimum data on reel:
Manufacturer, part number, ordering code, L value (in nH),
quantity, date of packing
Delivery mode
12-mm blister tape, reel packing (330-mm ∅ reel), packing unit: 2500 pcs.
Taping to IEC 60286-3. For details on taping and packing refer to data book
"Chokes and Inductors", page 302.
