Planar ER cores

MMG India offers low profile ER cores for SMD transformer application in power, signal and high permeability grades and these cores can also be gapped to suit customer requirements. Key features are; Very low total height, Low stray inductance, and High DC magnetic bias. Suitable applications are; Low power DC-DC converters, Pulse transformers, Broadband transformers, and Driver transformers. Planar ER cores are available in a range of sizes and materials as per IEC 62317-9
