Double Chokes B82796-S0
Rated voltage 42 Vac/80 Vdc
Rated current 0,4 to 1,2 A
Rated inductance 5 µH to 4,7 mH
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
Applications
■ B82796-C:
Suppression of asymmetrical interference coupled in on lines,
whereas data signals up to some MHz can pass unaffectedly
■ B82796-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
