RM Core - MMG Canada Ltd.

1 RM CoreComponentsRM CoreComponentsRM CoresRM (Rectangular modulus) cores arose due to the demand for coil formers with integrated pins that allow forefficient winding and high PCB packing densities. Clamps engaging in recesses in the core base hold the cores inplace, meaning glue is not normally required in this the cores adhere to specifications laid down in IEC 431 and in DIN 41980. The coil formers adhere to cores are designed for two main applications:-Highly stable, extremely low loss filter inductors and other resonance determining inductors (F58, P11).-Low distortion broadband transmission at low signal modulation (F39, F10, F9).RM cores can also be supplied without the centre hole.

2 These have a higher AL value and cross sectional areaand are used for power transformer applications (F47, F44, F45, F5A).RM CoreCoilformerRM CoreClipClipAdjusterRM 429-900-RM 429-900-Part Number64-020-6664-021-6676-024-95 Parameter l /AEffective LengthEffective AreaMinimum AreaEffective Core Parameters Electrical SpecificationIn accordance with IEC Document 60205.
