Rated voltage 42 VAC/80 DC
Rated current 200 to 1000 mA
Rated inductance 5
mH to 4,7 mH
Construction
Current-compensated ring core choke with ferrite core
Bifilar winding (B82790C0*/K0*)
Sector winding (B82790S0*/L0*)
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
B82790C0*/K0*:
Suppression of asymmetrical interference coupled in on lines,
whereas data signals up to some MHz can pass unaffectedly
B82790S0*/L0*:
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
Lead-free tinned
