EFD20/10/7 B66417G0000X608 Ferrite core B66417 Magnetic characteristics (per set) -1 l/A = 1.52 mm l = 47 mm e 2 A = 31 mm e 2 A = 31 mm min 3 V = 1460 mm e Approx. weight 7.2 g/set Delivery mode In pieces Packing Standard Styrofoam Tray (size 200 mm 300 mm) 1) A value L Material Pv Ordering code max e nH W/Set PC200 560 +30/-20% 680 < 0.45 (1000 kHz, 50 mT, 100 C) B66417G0000X608 < 0.55 (2000 kHz, 30 mT, 100 C) 2) 2) 780 +30/-20% 940 < 0.65 (1000 kHz, 50 mT, 100 C) 2) < 1.35 (2000 kHz, 30 mT, 100 C) 1) Measurement Parameter: 10 kHz, 0.25 mT, 100 turns, room temperature. A value is measured acc. to IEC62044-2. An appropriate wringing of cores with polished surface is used to improve reproducibility of L the measurement. (It is recommended to rub the mating surfaces themselves six times in a circular or elliptic arc that matches the core profile before measuring A value). L 2) Magnetised (magnetised in DC field strength H = 200 A/m for 10 s) Material PC200 is not suitable for applications with strong magnetic fields above 80 A/m. With respect to power loss characteristics, customer should assure that there is no overheating in an application.
