LCD TV & PLASMA TV COMPONENTS (continued)
Active PFC Coil
Series 2182.5 – Power-Factor-Correction Coil
Applications
This choke is mainly intended to be used as harmonics coils for high-end 22” LCD TV sets to make
them comply with the EN61000-3-2 standard. The most suitable circuit topology for this choke is a
transition-mode controlled boost DC/DC converter (i.e. MC33262 from ON Semiconductor). The
common range of operation for this choke is from 50-150 kHz.
Features
● Magnetic circuit of chokes consists of EE-type ferrite core having a squared central leg where
the windings and the air gap are placed
● Maximum primary power: 100 W @ 100 kHz
● Layer technology, enameled Lizt wire are recommended for proximity and skin effect reduction
Mechanical and Magnetic Data
● Pin-out configuration: 10 dual-in-line pins (5+5) with 25mm spacing
and 5mm pitch
● The ferrite core is E30/15/7-type, resulting in a component height
down to 22mm above the PCB
● Maximum horizontal dimensions: 24mm x 30mm
Options
● Customized electrical design and pinout
SLOT SMT CCFL
Series 7001 – Switch-Mode Transformers for Cold-Cathode
Florescent Lamp (CCFL) Inverters
Applications
These transformers are mainly intended to be used as Switch-ModeTransformers for
LCD TV sets from 15” to 37”, as DC/AC inverters for CCFL backlight or supplied as
complete inverter backlight board to be assembled to the LCD panel for its power supply.
Features
● The magnetic circuit of these transformers consists of two UI (FRM)-/EFD-type, low-profile
ferrite cores having rectangular central leg where the windings and the air gap are placed
● Maximum Output Power: 6 W @ 50 kHz
● Slot technology, copper wire windings
● Non-potted construction
● Start-up Output Voltage: 2 kVrms; Open Output Voltage: 1.6k Vrms; Lamp Voltage: 750 Vrms
Mechanical and Magnetic Data
● Low-profile, horizontal SMD coil-formers result in a component height down
to 5mm above the PCB
● Maximum horizontal dimensions: 32mm x 21mm
Options
● Customized electrical design and pinout
● Wide core shapes and size range availability: UI-8.8~17, EFD-10~25
● Potted construction on request
