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