Chokes for data and signal lines B82789*N I core choke, EIA 1812 Rated voltage 42 VAC/80 VDC Rated current 150 to 300 mA Rated inductance 11 to 100 µH 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: Suppression of asymmetrical (by LR) and symmetrical interference (by LS) 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 ∅ reel), packing unit: 2500 pcs. Taping to IEC 60286-3.
