B82731 Datasheet, PDF (1/5 Pages) EPCOS – Chokes for Power Lines D Core Chokes

Chokes for Power Lines
D Core Chokes
Rated voltage 250 Vac
Rated current 0,35 to 4,6 A
Rated inductance 3,3 to 100 mH
Construction
s Current-compensated double choke
with closed, rectangular ferrite core
s Closed polycarbonate coil former with 4 sections
s Without encapsulation
s 2-section winding
s Creepage distances and clearances > 3 mm
Features
s Coil former flame-retardant as per UL 94 V-0
s Recycleable owing to omission of encapsulation and glue
s High resonance frequency due to 2-section winding
s Low leakage due to closed core shape
s High pulse strength
s Low whirring noise
s Approx. 1 % stray inductance for symmetrical
interference suppression
Applications
s Electronic ballasts for lamps
s Switch-mode power supplies for TV sets
Terminals
s Tinned
s Pins fitting standard PCB grid
