| Document 414 ADSL2 Transformer For Broadcom BCM6348 Router Chip * Designed for use with the Broadcom BCM6348 router chip * Low leakage inductance and 1875 V interwinding isolation * Evaluated and approved by UL to meet 60950 under a Supplementary Insulation System with a working voltage of 250 Vrms, 353.5 V peak. Core material Ferrite Terminations RoHS tin-silver over tin over nickel over phos bronze. Other terminations available at additional cost. Weight 6.2 g Ambient temperature -40C to +85C Storage temperature Component: -40C to +85C. Packaging: -40C to +80C Resistance to soldering heat Max three 40 second reflows at +260C, parts cooled to room temperature between cycles Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30C / 85% relative humidity) Mean Time Between Failures (MTBF) 26,315,789 hours Packaging 175 per 13 reel Plastic tape: 32 mm wide, 0.42 mm thick, 28 mm pocket spacing, 12.9 mm pocket depth PCB washing Only pure water or alcohol recommended Part number1 B0727-BL_ Line side Leakage Turns ratio inductance2 inductance3 Capacitance4 line : chip 5% (H) max (H) max (pF) 2 :1 409.5 6.5 65.0 DCR max (Ohms) chip side line side 0.645 (1-4) 0.645 (2-5) 0.284 (10-7) 0.371 ((9-6) Longitudinal balance min (dB) 50.0 (1.1 MHz) THD max (dB) -80 1. When ordering, please specify termination and packaging coded: B0727-BLD Termination: L = RoHS tin-silver over tin over nickel over phos bronze. Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging: D = 13 machine-ready reel. EIA-481 embossed plastic tape (175 parts per full reel). B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead. 2.
