Chokes for Data and Signal Lines B82790-C0***-N2 Double Chokes B82790-S0***-N2 Rated voltage 42 Vac/80 Vdc Rated current 200 to 1000 mA Rated inductance 5 µH to 4,7 mH Construction ■ Current-compensated ring core choke with ferrite core ■ Bifilar winding (B82790-C…) ■ Sector winding (B82790-S…) Features ■ Case flame-retardant as per UL 94 V-0 ■ Suitable for reflow soldering Special types for conductive adhesion and ambient temperatures up to 150˚C on request Applications ■ B82790-C: Suppression of asymmetrical interference coupled in on lines, whereas data signals up to some MHz can pass unaffectedly ■ 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 ■ Tinned Marking Manufacturer, ordering code (short form), date of manufacture, coded (year, day of week, calender week) Delivery mode Blister tape, reel packing For details on taping, packing and packing units see page 302 252 04/00 Chokes for Data and Signal Lines B82790-C0***-N2 Double Chokes B82790-S0***-N2 Dimensional drawing 0,25±0,05 0,25±0,1 5,2 max. 4,9 max. 0...6 0,6±0,05 2,5±0,1 1,9±0,2 6,0 max.
