Notes From Tables
Dual Surface Mount Transformer Modules,
1500Vrms, Extended Temperature Range
1. 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. T1220T).
6.
Return Loss
— ITU-T G.703 and 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.

Application Notes

2.
ET Product
— All coils have an ET product of 10V-µsec
minimum.
Flammability
— Materials used in the products are
recognized as UL94-VO approved. Products meet the require-
ments of IEC 695-2-2 (Needle Flame Test).
Balance Characteristics
— The transformers meet the
requirements for longitudinal balance of FCC part 68.
Common Mode Rejection Ratio
— the CMRR for all
transformers is better than 50dB at 1MHz. A typical test circuit
is shown below.
Crosstalk Attenuation
— In the packages which contain
transmit and receive transformers side by side, sufficient
crosstalk attenuation is achieved by the inherent characteris-
tics of the toroid cores as well as by their proper positioning.
The crosstalk attenuation is typically 65dB or better. This
result was established with the test circuit shown below.
8.
9.
Surge Voltage Capability
– All transformers and chokes
meet surge voltage tests according to the most stringent
regulatory documents, when used with the proper voltage and current
suppression devices:
Metallic Voltage:
800V peak, 10/560µsec
Longitudinal Voltage: 2,400V peak, 10/700µsec
Isolation Voltage
— 100% of transformers are tested during
production to the specified isolation voltage level.
General Information
— The transformers are specifically designed for
use in 1.544Mbps (T1), 2.048Mbps (CEPT) and ISDN Primary rate
(PRI) interface applications. They are matched to the majority of the
line interface transceiver ICs currently available. Use of the proper
transformer allows the interface circuit to comply with ITU-T G.703 and
other standards regarding pulse waveform, return loss, and balance.
