Extended Temperature Range Models - For extended temperature range transformers (-40�C to +85�C operating temperature range), OCL (Open Circuit Inductance) is specified at both -40�C and +25�C. At -40�C, OCL is 600 μH minimum. All other parameters are specified at +25�C only. 2. Turns ratio is specified primary: secondary (CT = Center Tap). 3. Standard packaging for the surface mount package is anti-static tubes. Optional Tape & Reel can be ordered by adding a “T” suffix to the part number, (i.e T1176NLT).

Flammability - Materials used in these products are recognized as UL94-VO approved. Products meet the requirements of IEC 695-2-2 (Needle Flame Test). 2. Balance Characteristics - The transformers meet the requirements for longitudinal balance of FCC part 68. 3. Common Mode Rejection Ratio - the CMRR for all transformers is better than 50 dB at 1 MHz. 4. Crosstalk Attenuation - In the packages which contain transmit and receive transformers side by side, sufficient crosstalk attenuation is achieved by the inherent charact -eristics of the toroid cores as well as by their proper pos -itioning. The crosstalk attenuation is typically 65 dB or better. Frequency 50-100 KHz 100KHz-2 MHz 2-3 MHz Return Loss XMIT 9 dB 15 dB 11 dB RCV 12 dB 18 dB 14 dB 6. General information - The transformers are specifically designed for use in 1.544 Mbps (T1), 2.048 Mbps (CEPT) and ISDN Primary Rate Interface (PRI) applications. They are matched to the majority of the line interface transceiver ICs currently available. Use of the proper trans -former allows the interface circuit to comply with ITU-T G.703 and other standards regarding pulse waveform, return loss, and balance. 5. Return Loss - ITU-T G703 and the European national regulatory documents specify minimum return loss levels. The transformers will allow these limits to be complied within the situations where they are applicable.
