A center tapped winding can be created by connecting two ends of a Trans & Rec split center winding together on the printed circuit board. In ISDN-S AMD Am 79C30A/79C32A T5006 applications, the primary winding is the line side transformer winding. T7250/7256/7259 T5005 B. Minimum primary inductance and maximum distributed capacitance AT&T/Lucent T7903 T5007 satisfy the transmitter output and receiver input impedance require- ments of CCITT I.430 for both the TE and the NT. The maximum Mietec MTC-2072 T5007 distributed capacitance allows sufficient margin for the capacitance of Mitel MT8930 T5007 the IC and a protection diode network. It is consistent with the overall MC145474/145475 T5008 maximum value specified and the permitted length of the basic access Motorola MC145574 T5005 TE cord. D National TP3420/3421 T5007 C. The maximum specified unbalanced DC current capability is based on 20 mH minimum primary OCL. SGS Thomson ST5420, ST5421 T5007 D. National recommends a 1:2 receive transformer, but used as a 1:1 ratio PEB 2080/2081/2085 by connecting only half the secondary winding. Siemens PSB 2186 T5007 PEB 2084/2086 E. Standard packaging for all transformers on this data sheet is anti-static tubes. Optional Tape & Reel packaging can be ordered by adding a Yamaha 7405B, YTD421 T5007 suffix, (i.e: T5005NLT).

Safety Standards Recognition All transformers listed in the user network interface be transformer coupled. this data sheet are recognized to UL 1459 and UL 1950 as a basic insulation barrier. The transformer provides isolation for the line card or the terminal from the line. It is also a way to provide phantom 3. Flammability Materials used in the products are recognized UL94-VO. Products meet the requirements of power feeding to the terminal over the S-loop. Each end IEC 695-2-2 (needle flame test). requires a transmit and a receive transformer. Chokes are used in some applications to reduce common mode noise. 4. For more application notes please refer to data sheet T604.
