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” 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
