Chokes for Data and Signal Lines
I Core Choke, EIA 1812
B82789***H
Rated voltage 42 V /80V-
Rated inductance 11 to 100 H
Rated current 150 to 300 mA
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:
Supression of asymmetrical (by L
R
) and symmetrical inteference (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),
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 Ø 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
