tr01110.tif (546242 bytes)

Introduction

The TR01110 is a miniature high quality line isolation transformer, designed to provide an isolation barrier between telecommunications circuits and voice band termination equipment/modems.

The transformer has been designed to be compliant with BS60950 for reinforced insulation and EN41003, and carries a BABT certificate of recognition (No. CR0105).

Suitable for both 600ohm and complex termination impedances it will give a good margin of performance above the requirements of TBR15,17 and 21.

Construction

The Transformer is resin cast, and will fit directly on to a printed circuit board, utilising standard 0.1" pitch, which automatically gives a 12mm creepage between the Isolated Windings.
