EPCOS B82790-S0253-N201

Chokes for Data and Signal Lines
B82790-C0***-N2
Double Chokes
B82790-S0***-N2
Rated voltage 42 Vac/80 Vdc
Rated current 200 to 1000 mA
Rated inductance 5 µH to 4,7 mH
Construction
■ Current-compensated ring core choke with ferrite core
■ Bifilar winding (B82790-C…)
■ Sector winding (B82790-S…)
Features
■ Case flame-retardant as per UL 94 V-0
■ Suitable for reflow soldering
Special types for conductive adhesion
and ambient temperatures up to 150˚C on request
Applications
■ B82790-C:
Suppression of asymmetrical interference coupled in on lines,
whereas data signals up to some MHz can pass unaffectedly
■ B82790-S:
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
Terminals
■ Tinned
