MAGNETIC POWDER CORES PRODUCT LINE - UP Product SummaryCross Sectional ViewCeramicLayerMagnetic PowderPowder CORES are distributed air gap CORES made from ferrous alloypowders for low losses at high frequencies. Small air gaps distributedevenly throughout the CORES increase the amount of Direct Current (DC)that can be passed through the winding before core saturation occurs.

3 Molybdenum Permalloy POWDER (MPP) CORES are ideal for low loss inductorssuch as switching regulators and noise Flux, Sendust and Mega Fluxcores are the preferred choices forPower Factor Correction (PFC), switching regulator inductors, in-line noisefilters, pulse and flyback transformers and many other applicationsrequiring low losses at high Sung Corporation sadvanced technology enablesus to fulfill the diverse needsof our clients for soft magneticpowder POWDER CORES :::04 Chang Sung Corporation manufactures four types of soft MAGNETIC POWDER CORES including the Molybdenum Permalloy(MPP), High Flux, Sendust and Mega Flux, which are mainly used for inductors and transformers requiring low losses andinductance stability under high DC bias conditions. A fully standardized production management system under strictquality control of the raw materials (nickel, iron, molybdenum, aluminum and silicon) enables CSC to guarantee consistentquality and thus build greater confidence in our company s product Ni-Fe-Mo alloy POWDER CORES are made from alloy powders ofnickel, iron and CORES exhibit a highly sustainable stability in temperature and inductance under high DCmagnetization or high DC Bias conditions.

4 They offer the highest permeability among ourmaterials and the lowest core loss compared to any other core material. MPP CORES are alsoconsidered to be a premium material for direct current output inductors for SMPS includinghigh Q filters, loading coils and EMI/RFI filters. Finished toroid CORES are coated with a grayepoxy to provide dielectric protection and added physical FLUXNi-Fe alloy powdercores are made from alloy powders of nickel and 15,000 Gauss saturation level of High Flux CORES has a higher energy storage capabilityand more effective permeability when compared to the performance of gapped ferrite orpowdered iron CORES of a similar size. The excellent DC bias characteristics and low core lossesof High Flux CORES offer a reduction in size and the number of winding turns as well as superiormagnetic properties.

5 CSC High Flux CORES are excellent choices for applications such as PFCreactors, switching regulator inductors, in-line noise filters, pulse transformers and flybacktransformers. Finished High Flux CORES are coated with a Khaki epoxy and come in a variety ofshapes and alloy powdercores are made from alloy powders of iron,silicon and magnetostriction makes Sendust CORES ideal for eliminating audible noise in filterinductors. core losses of Sendust CORES are significantly lower than those of powdered ironcores. Especially Sendust E shapes provide a higher energy storage capability than gappedFerrite E CORES . Gap losses and eddy current losses are minimized with Sendust E corescompared to gapped ferrite E shapes. Sendust CORES are a smart choice for PFC circuits. Othermajor applications include switching regulator inductors, In-line noise filters, pulsetransformers and flyback transformers.

6 Finished Sendust CORES are coated in a black FLUXFe-Si alloy POWDER CORES are made from an alloy of iron and has developed new MAGNETIC alloy POWDER CORES for the first time in the world under the name ofMega Flux. The innovative design of these unique CORES includes a smaller size, higher current andhigher energy storage capability. Mega Fluxcores have higher flux density than any other magneticmaterial, 16,000 Gauss compared to 15,000 Gauss for High Flux CORES and 10,000 Gauss for Sendustcores. The extremely good DC bias characteristics provide the best solution for high end applicationssuch as buck/boost inductors for high power supply systems, smoothing chokes for inverters andreactors for electric vehicles. Mega Fluxcores pressed with no organic binder have significantly lowercore losses than powdered iron CORES and Fe-Si strip CORES .
