Document 243 Ultra-Small CO Driver Transformers This product is not RoHS-compliant. Contact Coilcraft for current status or possible alternatives. To meet the demand for even higher density DSLAM configurations, Coilcraft has introduced these ultra-small Central Office magnetics. These line driver transformers come in an EP7 package. Compared to conventional EP13 designs, they feature: • 58% less volume (under 0.078 in³) • 42% smaller footprint (just 0.22 in²) • 30% lower height (less than 0.36 in) Style Line side inductance (µH) Leakage inductance max (µH) AS8886-B AS9006-A AS9015-A SMD SMD SMD 1000 ± 6% 400 ± 5% 474 ± 10% 6.0 5.0 6.0 Part number Turns ratio line:chip Capacitance max (pF) Longitudinal balance (dB) min THD typ (dB) Designed to meet AS8886-B AS9006-A AS9015-A 1.81 : 1 1.80 : 1 1.41 : 1 N/A 40 35 45 (30 kHz - 1.1 MHz) 60 (at 100 kHz) 45 (20 kHz - 1.1 MHz) -85 at 20 kHz -85 at 100 kHz -92 at 20 kHz UL 1950 UL 1950 UL 1950 Part number Dielectric strength (V) DCR max (Ohms) Chip side Line side 0.44 (8-6), 0.44 (7-5) 0.23 (8-6), 0.27 (7-5) 0.58 (8-6), 0.75 (7-5) 0.87 (1-3, 2-4) 0.80 (1-3, 2-4) 0.94 (1-3, 2-4) 1875 1875 1875 1.
