Chokes for data and signal lines
B82793C0*/K0*
Double chokes
B82793S0*/L0*
Rated voltage 42 VAC/80 VDC
Rated current 400 to 2500 mA
Rated inductance 0.005 to 4.7 mH
Construction
Current-compensated ring core choke with ferrite core
Bifilar winding (B82793C0*/K0*)
Sector winding (B82793S0*/L0*)
Features
High rated currents
Reduced component height
Case flame-retardant as per UL 94 V-0
Suitable for reflow soldering
Applications
B82793C0*/K0*:
Suppression of asymmetrical interference coupled in on lines,
whereas data signals up to some MHz can pass unaffectedly.
B82793S0*/L0*:
Suppression of asymmetrical and symmetrical interference
coupled in on lines. The high-frequency portions of the symmetrical
data signal are decreased so far that EMC problems can be
significantly reduced.
Industrial applications
Terminals
Lead-free tinned
Marking
Manufacturer, ordering code (short form),
date of manufacture, coded (year, calender week, day of week)
Delivery mode
Blister tape, reel packing
For details on taping, packing and packing units see data book 2000
"Chokes and Inductors", page 302.
