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

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” LCDTV 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
