UR CORES

2020-06-04T00:51:32+00:00

UR ferrite cores are suitable for line output transformers (LOT) in TV sets. The round leg allows easy winding, also of strip conductors. Because of the high voltages involved, the round shape helps to prevent corona effect.

EPX Cores

2020-06-04T08:40:09+00:00

EPX ferrite cores are derived from EP cores specially for pulse transformers in ISDN and ADSL applications. In comparison to EP cores, they feature an increased center 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

P CORES

2020-06-04T08:41:20+00:00

Ferrite P cores are the earliest design for telecom filter inductors. As with RM cores there is a complete, standardized range (IEC133). The cores are available in a range of AL-value from many supplies. The core surrounds the winding almost completely so magnetic shielding is outstanding. The slots in the core are rather narrow which complicates assembly and

RM CORES

2020-06-03T07:35:09+00:00

RM cores are designed for use in high Q and high stability filter 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 supplies. The sizes are based on the standard PCB grid distance. RM5, for example, fits on a board space of

E CORES

2020-06-04T08:43:01+00:00

The shape of E cores is drived from the classical iron sheet lamination cores. For the original E range, the dimensions of the existing lamination range were take so that already commercially available coil formers and mounting hardware could be used. The former EF range has been optimized for the use of ferrite as a core material. Cross

EP CORES

2020-06-04T08:44:42+00:00

The EP ferrite core range was specially designed for wideband transformer applications. The shape of the assembly is almost cubical, allowing high packing densities on the PCB. The winding except the bottom is completely surrounded by ferrite. Shielding from neighboring cores is therefore excellent. The bobbins have two rows of pins allowing easy design of multiple output transformers.

Planar E CORES

2020-06-03T02:37:51+00:00

Planar magnetics offer an attractive alternative to conventional core shapes when a low profile magnetic devices are required. Basically this is a construction method of inductive components whose windings are fabricated using printed circuit tracks or copper stamping separated by insulating sheets or constructed from multilayer circuit boards. These windings are placed in low profile ferrite EE or

ETD CORES

2020-06-03T06:24:29+00:00

The ETD ferrite core design is a further development of E cores. They are optimized for use in SMPS transformers with switching frequencies between 50 and 200khz. The designation ETD (economic transformer design) implies that this design achieves maximum throughput power related to volume and weight of the total transformer. Shielding is somewhat improved compared with E cores.

ER CORES

2020-06-04T08:46:32+00:00

The ER core design is derived from the original E cores. Like ETD cores and EC cores, it has a round center pole and outer legs with a radius to accommodate round coil formers. These cores are mainly used for power transformers. The round center pole allows the use of thicker wires while the shorter turn length keeps

PM CORES

2020-06-04T08:48:55+00:00

Ferrite 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. Summary: Good shielding

PQ CORES

2020-06-03T07:13:29+00:00

Ferrite PQ cores, like RM/I cores, have round solid center poles and round winding areas. On the outside the design is rectangular. Top and bottom of a core set are completely flat, allowing good thermal contact with heat sinks. PQ cores are mainly used in power conversion. Therefore they are only offered in power materials. Most core sizes
