Data Line Chokes for Telecommunications UK0/UPN Interface; xDSL Transformers
Construction
■ Current-compensated ring core double choke with ferrite core ■ Plastic case
B82796C0... B82796S0...
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 Marking Ordering code, manufacturer, date of manufacture (month, year) Dimensional drawing
