HIGH FREQUENCY MAGNETICS

T1/E1 Through Hole Transformers

TM00116

•

Designed to operate at the rate of 1.544 Mbits/s as a

line interface pulse transfomer

•

Operating temperature range: -40°C to +85° C

Meets IEC 695, 2-2 flammability requirements

Only difference between the 2745C and 2745C2 is

the terminal length

PWB Process Capability: standard printed wiring board

assembly techniques, total-immersion cleaning

•

Reliability testing: Shock, vibration, temperature cycling,

temperature - humidity - bias
