Line Coupling / Bridging Transformer

TPA3858

TPA3858 is a 1 : 1 line match-

ing transformer with the fol-

lowing features.

Applications:

Interfacing equipment to tele-

phone line, requiring small

size and high insulation volt-

age.

•

Low profile.

Small volume.

Conforming to FCC part

68 and Canadian CS 03

regulations.

TPA3858-2 is designed for

high impedance bridging ap-

plications.

•

Low cost.

High insulation voltage.
