Mains Filter
Series 6001 – Frame-core Mains Filter*
Applications
These chokes are mainly intended to be used as common-mode
EMC mains filters for 22” to 42” LCD TV sets to make them comply
with the EN55022 standard.
Features
●
Magnetic circuit of these chokes consists of ET-type/FT-type
closed cores made by high-performance soft ferrite
●
Slot technology, enameled copper wire
●
Compact size even for high mains current values
●
High impedance and very low leakage flux
●
Low interwinding capacitance
Mechanical and Magnetic Data
●
Low-profile horizontal coil-formers result in a component height down
to 18mm above the PCB
●
Component height above the PCB according to the ferrite size
●
Maximum horizontal dimensions: 35mm x 35mm
Options
●
Customized pinout and inductance value
●
Available core size range: ET 20~35

Switch-Mode Transformers
Applications
These transformers are mainly intended to be used as Switch-Mode Transformers in high-end 26” to
42” LCD TV sets with mains insulation. The most suitable circuit topologies for these transformers are
one-transistor (standard core) or half-bridge (low-profile core) forward converters. The common range of
operation for these Switch-Mode Transformers is from 100 kHz to 200 kHz.
Features
●
Magnetic circuit of these transformers consists of two RM14-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 and TIW Lizt wire recommended for proximity and skin effects reduction
●
Copper-foil windings for high-current outputs
●
Mains insulation according to IEC60065 and IEC60950 safety standards
Mechanical and Magnetic Data
●
Pinout configuration: 12 in-line pins (6+6) with 35.6mm spacing
and 5.08mm pitch
●
Ferrite core can be either standard or low-profile RM14-type,
leading to a transformer height down to 21mm above the PCB
●
Maximum horizontal dimensions: 42mm x 44mm
(47mm x 44mm including mounting clips)
Options
●
Customized electrical design and pinout
●
Mounting clips
●
Total height above PCB: 30mm for standard RM14; 21mm for
low-profile RM14
