• Typical application is to isolate telecom equipment
such as CSUs and office repeaters from the T1line
• Compatible with water-soluble flux, total-immersion
cleaning, and machine insertion
• Shielded transformer reduces EMI
• Maximum ac current rating is 140mA for winding (6 - 7) • Designed for 100Ω terminating impedances
and 280mA for winding (4 - 1)
• Minimum interwinding breakdown voltage of 1000 Vrms
• Winding (4 - 1) is hardened to handle 6 amp current for
one second with no damage
• Meets IEC-695, 2-2 flammability requirements
• Qualified per Bellcore TR-TSY-000357-1
