Notes:
1. Extended Temperature Range Models - For extended temperature range transformers (-40ãC to +85ãC operating temperature range), OCL (Open Circuit Inductance) is specified at both
-40ãC and +25ãC. At -40ãC, OCL is 600 ȝH minimum. All other parameters are specified at +25ãC 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” sux to the part number, (i.e T1176NLT).

1. 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, sucient
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.
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.
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.
