required by ITU-T G.703) from -40° to +85° C
• Operating temperature range -40° to +85°C
• Meets IEC 695, 2-2 flammability requirements
• PWB Process Capability: standard printed wiring board
assembly techniques, total-immersion cleaning
• Reliability testing: Shock, vibration, temperature cycling,
temperature - humidity - bias
• Interwinding breakdown voltage: 1500 Vrms min
• UL 1950 approved: file number E150991
