HIGH FREQUENCY MAGNECTICS
T1/E1 Single Through Hole Transformers
TM00154
•
•
•
•
Operate as line-interface pulse transformers in DS1
and CEPT applications
•
•
•
Operating Temperature Range: -40° to +85° C
Meets IEC 695, 2-2 flammability requirements
2662B and 2662B2 contain specific interwinding
insulation to minimize capacitance
PWB Process Capability: Standard Printed Wiring Board
assembly techniques, total-immersion cleaning
Winding (3-2) (2-1) is highly balanced; Inductance
unbalance is 0.1%, max
•
•
Reliability testing: Shock, vibration, temperature cycling,
temperature - humidity - bias
Only difference between the 2662B and 2662B2 is
the terminal length; only difference between the
2662H and 2662H2 is the terminal length
Recommended transformer for new through-hole
applications is 2745AF2
