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).
