DTM Series * T3/DS3/E3/STS-1 Tri-Port Transformer Modules These modules contain both transmit and receive transformers designed for use in in T3/DS3 applications using bit rates off 44.736Mbps, E3 interfaces at 34.368Mbps and STS-1 applications at 51.84 Mbps The transformers are typical for 75 ohm bandwidth applications requiring a very fast rise times. Features * low cost SMD for pick and place compatability while providing consistent and reliable coplanarity * low leakage inductance * manufactured in an ISO-9001:2000, TS-16949:2002 and ISO-14001:2004 certified Talema facility * fully RoHS compliant and meets lead free reflow level J-STD-020C Electrical Specifications Ratings@ 25C ambient Minimum isolation voltage: 1500 Vrms Extended Operating Temperature Range: -40 to +85C DTM Series * Tri-Port SMD Wideband Interface Transformer Modules Extended Operating Temperature Range -40C to +85C Part Number DTM-100 Turns Ratio Pri/Sec 2% 1:1 OCL Primary @ 25C (H Min) 100 OCL Primary @ -40C (H Min) 40 LL (H Max) 0.11 CWW (pF Max) 12 Isolation Voltage (Vrms Min) 1500 1-2, 3-4, 5-6, 7-8, 9-10, 11-12 Primary Pins DTM Dimensions Suggested Pad Layout 0.040 (1.02) 1 Schematic 24 0.537 (13.64) 0.583 0.571 (14.80) (14.50) TALEMA IN WK / YR Part Nrumber 2 3 23 22 0.622 (15.80) 11 x 0.04(1.02) 0.440 (11.18) 0.240 0.201 (6.10) (5.10) 24 x 0.012 x 0.012 (0.30 x 0.30) 0.052 (1.31) 0.442 (11.22) 0.091 (2.30) 4 5 21 20 0.026 (0.66) 6 7 19 18 Surface coplanarity will be 0.004 (0.01) maximum 8 9 17 16 10 11 15 14 12 13 Germany: Int.+4989-841 00-0 * Ireland: Int.+35 374 - 954 8666 * Czech Rep: Int.+420 377 - 338 351 * India: Int.+91 427 - 244 1325 http://www.talema-nuvotem.com (10-06)Communications\E1-T1\DTM |
