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.

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
