Extended Temperature Range Models - For extended temperature range transformers (-40 C to +85 C operating temperature range), OCL (Open Circuit Inductance) is specied at both -40 C and +25 C. At -40 C, OCL is 600 H minimum. All other parameters are specied at +25 C only. 2. Turns ratio is specied 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 su x to the part number, (i.e T1176NLT).

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