B82791-H
B82791-G
Current-Compensated Ring Core Double Chokes
Rated voltage 250 Vac
Rated current 0,25 to 0,7 A
Rated inductance 4,7 to 47 mH
Construction
■ Current-compensated ring core double choke
with ferrite core
■ Polycarbonate case
■ Without potting
■ Sector winding
Features
■ Vertical and horizontal versions
■ Case flame-retardant as per UL 94 V-0
■ High resonance frequency owing to special
winding technique and omission of potting
■ > 1 % stray inductance for symmetrical
interference suppression
Applications
■ Compact and narrow electronic lamp ballasts
■ Telecom applications such as NTBA, PCMx
■ Integrated power supplies for video recorders,
portable TVs, SAT receivers, set-top boxes,
video-on-demand
■ Automation, e.g. sensor modules with integrated
power supplies
■ Electronic transformers, e.g. for halogen lamps
■ Plug-in and portable power supplies and chargers
for cellular and cordless phones
■ Compact, modular and desktop power supplies
Terminals
■ Fitting PCB standard grid
