247 04/00
Rated voltage 42 Vac/80 Vdc
Rated current 400 to 1200 mA
Rated inductance 5 µH to 4,7 mH
Construction
■Current-compensated ring core choke with ferrite core
■Bifilar winding (B82793-C…)
■Sector winding (B82793-S…)
Features
■High rated currents
■Reduced component height
■Case flame-retardant as per UL 94 V-0
■Suitable for reflow soldering
Applications
■B82793-C:
Suppression of asymmetrical interference coupled in on lines,
whereas data signals up to some MHz can pass unaffectedly
■B82793-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
■Tinned
Marking
