1:1 Line Isolation Transformer
Brand: VigortronixThese line transformers provide isolation between modems or similar devices and telephone Iines. This transformer is designed for use in voice or data transmission circuits where the line DC is diverted from the windings by a choke or solid state device. The use of this transformer should enable the equipment it is used with to comply with the relevant requirements of BS6305.
- Choice of through hole or ultra low profile surface mount
- Matching transformer
- Designed for use in data transmission circuits
- Available in OEP1200 and OEP8000 versions
