Product : HD SDI Galvanic Video and Ground Path Isolator, Surface Mount Model

Model No. : LF233


The L E N LF233 is a miniature surface mount Galvanic Isolator, providing full quality transmission of the HD SDI serial digital video signal format whilst blocking interference, DC bias and related problems.



 •   Full DC isolation between equipment

 •   Totally passive device, no power required

 •   Maintenance free

 •   Very low loss, minimal signal attenuation

 •   Protects equipment from damage by DC static and earth loop voltage build up

 •   Prevents errors due to differences in earth potential along the signal path

 •   No distortion of the HD-SDI signal

 •   Can be used with the SD-SDI and ASI signal formats

 •   Small and lightweight


Description / Details

Our L E N LF233 Isolator provides safeguarding both from signal distortion and against equipment damage by static and Earth Loop DC voltage build up, to meet these requirements. It is built in a surface mount package.

Transparent to the HD SDI and lower signal standards, the LF233 Isolator is designed to be mounted internally within equipment.
