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. Standard temperature range is 0°C to +70°C. 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 packaging can be ordered by adding a “T” suffix to the part number, (i.e. T1212NLT).

General Information — The transformers are specifically designed for use in 1.544 Mbps (T1), 2.048 Mbps (CEPT) and ISDN Primary Rate Interface (PRI) 5. Crosstalk Attenuation — In the packages which contain transmit applications. They are matched to the majority of the line interface transceiver and receive transformers side by side, sufficient crosstalk attenuation ICs currently available. Use of the proper transformer allows the interface circuit is achieved by the inherent characteristics of the toroid cores as well to comply with ITU-T G.703 and other standards regarding pulse waveform, as by their proper positioning. The crosstalk attenuation is typically return loss, and balance. 65 dB or better. 10. Transformer Selection Guide — Please contact Pulse Application Engineering 6. Return Loss — ITU-T G.703 and the European national regulatory or see our website for the latest Pulse Transformer Selection Guide. documents specify minimum return loss levels. The transformers will allow these limits to be complied within the situations where they are applicable.
