  • Pot CoresOpen or Close
    As pot cores are one of the oldest core designs. They are available in a wide range of worldwide standardized sizes - according to IEC 62317-2. Originally produced for filter inductors. pot cores are becoming increasingly popular in power applications. With the introduction of EMC legislation, electromagnetic screening has become a prime concern in core selection. The pot core's shape almost completely encloses the windings and whilst this can be a hindrance for access purpose, it provides excellent screening.

  • 4 Solt Pot CoresOpen or Close
    MMG India offer a wide range of 4 Slot Pot cores based on the old 'VlNKOR' series. The cores are supplied gapped to an effective permeability range and are adjustable for tuned filters up to 5MHz. The larger cross-sectional area offered by the 4 Slot range allows for a higher power setting than the conventional 2 Slot version. Also with the advantage of 2 more slots they can be used in applications where 1/2 and 1/4 turns are required. A full range of bobbins and mounting assemblies are also available.

  • Wide Solt CoresOpen or Close
    These cores are used extensively in telecommunications and converter power supply circuits. The wide slot in the lower half of the assembly enables a large number of connections to be brought out. These cores are also referred to as Touch Tone (TT) pot cores as were originally designed for push-button telephone sets.

  • RM Cores - RegularOpen or Close
    RM cores arose due the demand for the coil formers with integrated pins that allows for efficient winding and high PCB packing densities. Clamps engaging in recesses in the core base hold the cores place, meaning glue is not normally required in this process All the cores adhere to specifications laid down in IEC 62317-4 and in DIN 41980.

    RM cores are designated for two main applications:
    - Highly stable, extremely low loss filters inductors and other resonance determining inductors (F58,P11)
    - Low distortion broadband transmission at low signal modulation (F39,F10,F9)
    RM cores also be supplied without the centre hole. These have a higher AL value and cross sectional area and are used for power applications (F47,F44,F5A)

  • RM Cores - Low profileOpen or Close
    The increasing miniaturization of electronic circuits and Switched Mode power supplies being integrated into PCB philosophy, low profile components are necessary to overcome height restrictions. In some cases the conventional Windings can be replaced by printed circuit tracks directly onto the PCB.
    The RM core's low profile shape and ease of construction give significant advantages including, fast error free winding and efficient repeatable performance.

  • EE CoresOpen or Close
    EE Cores were one of the first ferrite cores to be manufactured, being derived from their respective iron lamination size. Having rectangular limbs they are relatively easy to manufacture and as such a vast range exists in the marketplace. MMG-India's range reflects a selection of cores that have become, over many years, worldwide standards through continued use. E cores are particularly suitable for power transformers and filters at low frequencies. They are not suitable in high frequency applications as the rectangular centre limb leads to higher leakage inductance and winding resistance. EE cores are available in a range of sizes and materials as per IEC 62317-8

  • Planar E CoresOpen or Close
    Many new electronics equipment will use switched mode power supplies where the voltage transformation unit is integrated on a circuit card. As cards may be racked with minimal clearances. low profile components are necessary. Planar assemblies differ radically from conventional transformers as wire windings are replaced by stacks or flat spiral laminations. In some cases the winding can be replaced by printing circuit tracks, with the E core inserted through the board. The planar E core's low profile shape and ease of construction offers significant advantages including: Fast error-free winding; excellent heat sinking properties and efficient repeatable performance at low cost. All the cores adhere to specifications laid down in IEC 62317-9

  • ETD CoresOpen or Close
    ETD (Economical Transformer Design) cores were developed specifically for Power Transformer cores used in Switched Mode power supplies. The combined cross-sectional area of the two outer limbs equals the cross-sectional area of the centre limb allowing an even flux distribution throughout the core. This ensures the absence of localised 'hot spots' that can reduce performance at high frequencies or high flux levels. Their round centre limb provides for minimal winding resistance, leakage inductance and copper eddy current losses. ETD Cores are available in a range of sizes and materials as per IEC 62317-6 together with their associated coil formers (both Horizontal and Vertical mounting) and clips.

  • EP CoresOpen or Close
    EP Cores have a particularly compact, low profile shape and offer excellent shielding from adjacent cores due to the winding being almost completely surrounded by the ferrite core. This allows for high packing densities on printed circuit boards. Originally designed for broadband, small power transformers and signal transmission applications, EP cores are well suited for the demanding properties required from modern electronic components.
    EP Cores are available in a range of sizes and materials as per IEC 62317-5.

  • UU Cores, UR CoresOpen or Close
    These cores are used for the construction of transformers in the frequency range from 10 to 500 kHz. The transferable outputs will be determined by core geometry and the upper frequency limits by the material selected. In previous years a major application was for in line transformers producing an electron deflection beam for CRT's. Materials used for these applications are characterized by high flux density, low specific power losses and the decline of losses dependent on temperature in the range from 200 to 1000C.
