(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.
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
