µH
to 4,7 mH
Construction
s
Current-compensated ring core choke with ferrite core
s
Bifilar winding (B82790-C…)
s
Sector winding (B82790-S…)
B82790-C0***-N2
B82790-S0***-N2
Features
s
Case flame-retardant as per UL 94 V-0
s
Suitable for reflow soldering
Special types for conductive adhesion
and ambient temperatures up to 150˚C on request
Applications
s
B82790-C:
Suppression of asymmetrical interference coupled in on lines,
whereas data signals up to some MHz can pass unaffectedly
s
B82790-S:
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
Terminals
s
Tinned
Marking
Manufacturer, ordering code (short form),
date of manufacture, coded (year, day of week, calender week)
Delivery mode
Blister tape, reel packing
