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.
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 PT design this problem is solved by cutting away the sides of one core half. This creates ample room for wires and coil former fl anges. A range of special PT coil formers is available but also most standard P core accessories can be used.
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. Planar ER cores are very suitable to build small SMD or planar power and signal tranformers. For the 3 smallest sizes matching SMD coil formers and clips are available.
The EQ core design is derived from the ER and PQ. The range is optimized for use in compact AC/DC notebook adapters and DC/DC converters. For instance, the EQ30 has the capability to handle a power range of 50 to 70 W (fl yback topology) in an enclosed casing of a notebook adapter or 100 to 150 W in low profi le DC/DC converter . The advantages of EQ cores are a simple core shape, round centre pole, high Ae value , a large winding window, low profi le and a large surface area for heat dissipation.
The ETD core design is a further development of E cores. They are optimized for use in SMPS transformers with switching frequencies between 50 and 200 kHz. 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. The matching coil formers are suitable for many winding types and can be handled on automatic equipment.
Economic Flat Design (EFD) power transformer cores offer a signifi cant advance in circuit miniaturization. Their low build height and high throughput power-density make them ideally suited to applications where space is at a premium. Throughput power of a ferrite core transformer is essentially proportional to its volume. So the transformer is one of the main limitations in a DC-DC converter's size. Now, with the introduction of the EFD system, a signifi cant reduction in transformer core height has been achieved. EFD transformer cores combine both extreme fl atness with a very high throughput power-density for frequencies up to 1 MHz and higher. Every transformer, based on the EFD range, has a lower building height than any other existing low-profi le design with the same magnetic volume. This is achieved by placing the centre pole of the core always in the centre of the fi nished transformer, thus making maximum use of the winding area.
The PH core range consists of potcore halves specially designed for use in proximity switches. Their shape is derived from the IEC standard P-core range. Outside diameters are adapted to fi t standardized sizes of proximity switch housings. Since the cores are used as halves, their height is increased to accommodate the winding. A complete range of coil formers is available.
The EP/LP core range was specially designed for wideband transformer applications where low build height is a must. The board area occupied by the assembly is almost a square, allowing high packing densities on the PCB. The bobbins have two rows of pins allowing easy design of multiple output transformers. Cores are available in high permeability materials, including the new low THD material 3E55, for wide band transformers and in power materials for small power transformers.
