(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.
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
Maximum primary power: 200 W @150 kHz for low-profile RM14;
250 W @ 150 kHz for standard RM14
Layer technology, enameled Lizt wire recommended for proximity and skin
effects reduction
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
Options
Customized electrical design and pinout
Mounting clips
2702 bobbin without through-hole flange available
Total height above the PCB: 30 mm for standard RM14; 21mm
for low-profile RM14

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
