Notes
center tapped winding created connecting ends split center winding together printed circuit board. ISDN-S applications, primary winding line side transformer winding. Minimum primary inductance maximum distributed capacitance satisfy transmitter output receiver input impedance requirements CCITT I.430 both maximum distributed capacitance allows sufficient margin capacitance protection diode network. consistent with overall maximum value specified permitted length basic access cord. maximum specified unbalanced current capability based minimum primary OCL. National recommends receive transformer, used ratio connecting only half secondary winding. Standard packaging transformers this data sheet anti-static tubes. Optional Tape Reel packaging ordered adding suffix, (i.e: T5005NLT).

Application Notes
General Information S-interface standardized four-wire digital telephone access point defined CCITT I-series recommendations Integrated Services Digital Network. This "basic rate access" accommodates 64Kbps "B-channels" information, 16Kbps "D-channel" intended signaling control, 48Kbps framing other purposes, giving total rate 192Kbps. CCITT physical layer recommends that user network interface transformer coupled. transformer provides isolation line card terminal from line. also provide phantom power feeding terminal over S-loop. Each requires transmit receive transformer. Chokes used some applications reduce common mode noise. transformers described this data sheet matched transceivers offered major manufacturers listed. transformer-chip pair assures that requirements CCITT I.430 with respect pulse waveform templates, impedance longitudinal balance. addition, transformers provide isolation voltages required regulatory agencies capable passing surge voltage tests. Safety Standards Recognition transformers listed this data sheet recognized 1459 1950 basic insulation barrier. Flammability Materials used products recognized UL94-VO. Products meet requirements 695-2-2 (needle flame test). more application notes please refer data sheet T604.
Common Mode Chokes
Please refer data sheet G002 selection high frequency common mode chokes.
