VDSL Hybrid Transformer
This VDSL hybrid line transformer is ideal for high
density DSLAM boards thanks to its small footprint
(8,13 × 5,08 mm) and leadless design.
The simple ceramic case totally eliminates coplanarity
problems and also makes the transformers extremely
economical.
Custom versions are also available to meet specific
applications.
