Ultra-Small CO Driver Transformers
This product is not RoHS-compliant. Contact Coilcraft
for current status or possible alternatives.
To meet the demand for even higher density DSLAM
configurations, Coilcraft has introduced these ultra-small
Central Office magnetics.
These line driver transformers come in an EP7 package.
Compared to conventional EP13 designs, they feature:
• 58% less volume (under 0.078 in³)
• 42% smaller footprint (just 0.22
in²)
• 30% lower height (less than 0.36 in)
