HIGH FREQUENCY MAGNETICS

T1/E1 Single THT Shielded Hardened Transformer

TM00122

•

Designed for T1 carrier applications at 1.544 Mbps

•

Compatible with water-soluble flux, total-immersion

cleaning, and machine insertion

Typical application is to isolate telecom equipment

such as CSUs and office repeaters from the T1line

•

Shielded transformer reduces EMI

•

Maximum ac current rating is 140mA for winding (6 - 7)

and 280mA for winding (4 - 1)

Designed for 100Ω terminating impedances

Minimum interwinding breakdown voltage of 1000 Vrms

Meets IEC-695, 2-2 flammability requirements

Qualified per Bellcore TR-TSY-000357-1

Winding (4 - 1) is hardened to handle 6 amp current for

one second with no damage
