T1/E1/CEPT/ISDN-PRI TRANSFORMER

Quad Port SMT Transformer/Choke Modules,

1500 Vrms, Extended Temperature Range

RoHS peak reflow temperature rating: 245°C

Optimized for enhanced EMC performance

Quad-port SMT package contains Transformers

with optional Common Mode Chokes on both

transmit and receive channels

Extended temperature range

Isolation Voltage: 1500 Vrms

Electrical Specifications @ 25°C — Operating Temperature -40°C to +85°C

NOTES: 1. Other Transformer/Choke modules available. Please contact Pulse Applications Engineering. Please refer to data sheet T622 for a list of

additional Octal Transformers without Common Mode Chokes.

2. RoHS compliant parts have an “NL” suffix at the end of the part number, TX1267NL.

3. To order Tape & Reel packaging add a “T” suffix to the part number (i.e. TX1263NL becomes TX1263NLT).
