Chokes for Data and Signal Lines B82793-C0 Double Chokes B82793-S0 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 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 302 247 04/00 Chokes for Data and Signal Lines B82793-C0 Double Chokes B82793-S0 A 0,3±0,05 4,9 max. 0...6 2,5±0,1 _ 0,05 0,6 +0,1 Dimensional drawing 7,1 max. _ 0,2 9 +0,4 6,0 max. max. 0,1 A Beschriftung Marking SSB1350-5 Layout recommendation 248 04/00 Chokes for Data and Signal Lines B82793-C0 Double Chokes B82793-S0 General technical data Rated voltage VR 42 Vac (50/60 Hz) 80 Vdc Rated current IR Referred to 50 Hz and 60 °C ambient temperature Rated inductance LR Measured with HP 4275A Measuring frequency at L ≤ 1 mH = 100 kHz, 0,1 mA L > 1 mH = 10 kHz, 0,1 mA (specified per winding) Inductance tolerance B82793-+****-N201/N215: ± 30 % B82793-+****-N265: – 30/+ 50 % Inductance decrease ∆L/L0 < 10 % at dc magnetic bias with IR Stray inductance LS Measured with HP 4275A Measuring frequency at L ≤ 11 µH = 1 MHz, 5 mA L > 11 µH = 100 kHz, 5 mA DC resistance Rtyp Typical values, measured at 20 °C ambient temperature Solderability (215 3) ˚C, (3 0,3) s wetting of soldering area ≥ 95 % in accordance with IEC 60068-2-58 Climatic category 40/125/56 (– 40 °C/+ 125 °C/56 days damp heat test) in accordance with IEC 60068-1 Weight Approx. 0,25 g Characteristics and ordering codes LR mH LS, typ nH IR 1) mA Rtyp mΩ VT Vdc, 2 s Ordering code 0,005 0,011 0,025 0,051 0,470 1,0 2,2 4,7 50 50 1500 2000 200 250 250 300 1200 800 800 800 700 700 500 400 100 120 130 160 200 200 400 550 250 250 250 250 750 750 750 750 B82793-C0502-N201 B82793-C0113-N201 B82793-S0253-N201 B82793-S0513-N201 B82793-C0474-N215 B82793-C0105-N265 B82793-C0225-N265 B82793-C0475-N265 1) Types with higher rated current upon request. 249 04/00 Chokes for Data and Signal Lines B82793-C0 Double Chokes B82793-S0 Insertion loss αe (typical values at Z = 50 Ω) asymmetrical, all branches in parallel (common mode) symmetrical (differential mode) B82793-C0502-N201 B82793-C0113-N201 SSB0871-I 50 dB αe 40 30 20 10 0 _1 10 B82793-S0253-N201 10 0 B82793-S0513-N201 250 04/00 10 1 10 2 MHz 10 3 f Chokes for Data and Signal Lines B82793-C0 Double Chokes B82793-S0 Insertion loss αe (typical values at Z = 50 Ω) asymmetrical, all branches in parallel (common mode) symmetrical (differential mode) B82793-C0474-N215 B82793-C0105-N265 SSB1352-L 50 dB αe αe 40 40 30 30 20 20 10 10 0 _2 10 10 _1 10 0 0 _ 10 2 10 1 MHz 10 2 f B82793-C0225-N265 10 _1 10 0 10 1 MHz 10 2 3 f B82793-C0475-N265 SSB1353-U 50 SSB1354-3 50 dB dB αe αe 40 40 30 30 20 20 10 10 0 _2 10 SSB1351-D 50 dB 10 _1 10 0 10 1 10 2 MHz f 0 _2 10 251 04/00 10 _1 10 0 10 1 MHz 10 2 f
