Supplier From Dongguan, Guangdong, China
Supplier Of Electric Transformers
 
PM cores are a variation on classic P cores, suitable for large high power transformers and energy storage chokes. They have larger wire slots facilitating easy assembly, but still the good shielding of a closed core shape.
PM cores can be found in transmission and radar equipment and in various high power industrial installations.

  Chen Pei Enterprise Co., Ltd.
Supplier From Dongguan, Guangdong, China
Supplier Of Electric Transformers
 
Toroids have the best possible shape from the magnetic point of view. The flux path is completely closed so the capabilities of the ferrite are fully exploited. Especially for high permeability ferrites
the effect of even a minor airgap in the magnetic circuit
can spoil up to 50% of the effective permeability. A further
advantage is the very low leakage fi eld which makes it a
suitable shape for power and pulse transformers.
Ring cores are mainly used for pulse- and wide band transformers and interference suppression coils but also in
special power supplies.

  Chen Pei Enterprise Co., Ltd.
Supplier From Dongguan, Guangdong, China
Supplier Of Electric Transformers
 
Due to the high saturation fl ux density
of iron powder (950...1600 mT) these
ring cores are very suitable for output
chokes carrying high DC currents.
Another application is found in lamp
dimmers as ballast choke.
The cores are made of electrolytic iron
powder, mixed with a small amount of
resin for insulation. They are coated
with polyamide 11 (thickness 0.1 - 0.3
mm). The isolation voltage between
core and winding is up to 1500 V.

  Chen Pei Enterprise Co., Ltd.
Supplier From Dongguan, Guangdong, China

RM cores were designed for use in high Q, high stability fi lter inductors.
Their shape allows economic utilization of surface area on the PCB. The range is standardized in IEC 431 and is available worldwide from many suppliers. The sizes are based on the standard PCB grid distance. RM 5, for instance, fi ts on a board space of 5 x 5 modules of 2.5 mm grid. Coil formers and clips were optimized for automated winding and mounting.
The slots provide suffi cient space for leads of windings. Magnetic shielding is not as good as with P-cores, but still
effective.

The shape of EI cores, more precisely a core set consisting of an E core and an I core, is magnetically equivalent to an E core set with shorter legs. For typical characteristics, see therefore the E core section.

  Chen Pei Enterprise Co., Ltd.
Supplier From Dongguan, Guangdong, China
Supplier Of Electric Transformers
 
A disadvantage of the classical P core design has always been the narrow wire slots, making it diffi cult to make strong coil formers with integrated solder pins.
In the PTS design this problem is solved by cutting away the sides of both core halves. This creates ample room for wires and coil former fl anges.

A range of special PTS coil formers is available but also most standard P core accessories can be used.

  Chen Pei Enterprise Co., Ltd.
Supplier From Dongguan, Guangdong, China
Supplier Of Electric Transformers
 
U cores, with rectangular crosssections, are easy to produce and are relatively inexpensive. For this reason they are very popular in low cost applications such as interference fi lters and output chokes in radio and TV equipment. There is no real optimization for transformer winding designs and the core is rather bulky.
Large U cores like U93 and U100 are suitable for very high throughput powers. They can be stacked to form transformers, capable of handling several kW's in applications such as
industrial HF welding.

  Chen Pei Enterprise Co., Ltd.
Supplier From Dongguan, Guangdong, China
Supplier Of Electric Transformers
 
The ER core design is derived from the original E core and, like
ETD and EC cores, has a round centre pole and outer legs with a
radius to accomodate round coil formers.
These cores are mainly used for power transformers. The round
centre pole allows the use of thicker wires while the shorter turn
length keeps the copper losses low.

  Chen Pei Enterprise Co., Ltd.
Supplier From Dongguan, Guangdong, China
Supplier Of Electric Transformers
 
PQ cores, like RM/I cores, have round
solid centre poles and round winding
areas.
On the outside the design is
rectangular. Top and bottom of a core
set are completely fl at, allowing good
thermal contact with heat sinks.
PQ cores are mainly used in power
conversion. Therefore they are only
offered in power materials. For most
core sizes matching coil formers are
available.

P cores with solid centre poles have approximately a 15% higher effective area than the corresponding P cores with central hole. This makes them more suitable for applications where high fl ux densities are used. This will be the case in power conversion where the P core is still popular mainly because of its excellent magnetic shielding. This helps to avoid EMI problems, especially
at higher switching frequencies.

EPX cores were derived from EP cores
specially for pulse transformers in ISDN
and ADSL applications. In comparison
to EP cores they feature an increased
centre pole area and achieve the same
AL and THD performance in a smaller
core volume. The new EPX designs,
complete with SMD bobbin and clip,
satisfy the need for slimmer pulse
transformers.
They are available in the high permeability
material 3E6 for ISDN pulse
transformers and in the low harmonic
distortion material 3E55 for ADSL
wideband applications. Power materials
are introduced along with these.
