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
