EPCOS B82796C0 Data line chokes for telecommunications xdsl transformer Datasheet

Data Line Chokes for Telecommunications
B82796C0...
UK0/UPN Interface; xDSL Transformers
B82796S0...
Construction
■ Current-compensated ring core double choke with ferrite core
■ Plastic case
Features
■ Case flame-retardant as per UL 94 V-0
■ Suitable for automatic insertion
■ Pins fitting standard PCB grid
Applications
■ B82796C:
Suppression of asymmetrical interference coupled in on lines,
whereas data signals up to some MHz can pass unaffectedly
■ B82796S:
Suppression of asymmetrical and symmetrical interference
coupled in on lines. The high-frequency portions of the symmetrical
data signal are decreased so far that EMC problems can be
significantly reduced
