LCDTV & PLASMATV COMPONENTS (continued)

Passive PFC Coil

Series 6001 – Laminated-core Power-Factor-Correction Coil

Applications

These chokes are mainly intended to be used as harmonics coils for high-end 30” to 42” LCD TV sets to

make them comply with the EN61000-3-2 standard. These components are suitable for operation at

mains frequency (50-60 Hz)

Features

●

Magnetic circuit of these chokes consists of UU or EI laminated cores made by high performance

silicon steel

●

Single-winding (EI) or double-winding (UU) construction

Acoustical noise-free construction

Input power up to 200 W @ mains frequency with EI-42 core size and horizontal dimensions down

to 42mm x 56mm

Mechanical and Magnetic Data

●

High permeability and saturation flux density core

High inductance value allowed

Low-profile horizontal coil-formers result in a component height down to 28mm above the PCB

Options

●

Customized pinout and inductance value

Core fixing by mylar tape or argon welding

Available core dimensions up to EI-66 and UU-40

Active PFC Coil

Series 2712 (standard core), Series 2702 (low-profile core),

Power-Factor-Correction Coil

Applications

These chokes are mainly intended to be used as harmonics coils for

high-end 26” to 42” LCD TV sets to make them comply with the

EN61000-3-2 standard. The most suitable circuit topology for these

chokes is transition-mode controlled boost DC/DC converter (i.e. L6561

from ST or MC33262 from ON Semiconductor). The common range of

operation for these chokes is from 100-200 kHz.

Mechanical and Magnetic Data

Pinout configuration: 12 in-line pins (6+6) with 35.56mm spacing

and 5.08mm pitch

●

The ferrite core can be either standard or low-profile RM14-type,

resulting in a component height down to 21mm above the PCB

Features

●

Magnetic circuit of chokes consists of two, RN14-type ferrite

cores having a round central leg where the windings and the air

gap are placed

Options

●

Customized electrical design and pinout

Mounting clips

●

Maximum primary power: 200 W @150 kHz for low-profile RM14;

250 W @ 150 kHz for standard RM14

2702 bobbin without through-hole flange available

Total height above the PCB: 30 mm for standard RM14; 21mm

for low-profile RM14

Layer technology, enameled Lizt wire recommended for proximity and skin

effects reduction
