Line Coupling / Bridging Transformer
TPA3858 is a 1 : 1 line match-
ing transformer with the fol-
lowing features.
• Low profile.
• Small volume.
• Conforming to FCC part
68 and Canadian CS 03
regulations.
• Low cost.
• High insulation voltage.
Applications:
Interfacing equipment to tele-
phone line, requiring small
size and high insulation volt-
age.
TPA3858-2 is designed for
high impedance bridging ap-
plications.
