With the recent demise of Mahan as a manufacturer of powder cores, former customers will be struggling to source Mahan cores over the coming months and will be looking towards alternatives. Our advice is to contact Power Magnetics for a quotation on an equivalent Micrometals core. It may be that these are not quite as cheap as the Mahan core used to be, but Micrometals are undisputedly a league above the clone manufacturers. All iron powder cores suffer from a certain degree of thermal ageing, but Micrometals cores suffer significantly less from thermal ageing degradation than was the case with Mahan cores. It seems that you do get what you pay for and product quality will be improved by a move to Micrometals Iron Powder Cores.
Check out our range of Cosmo Ferrites They provide a high quality, low cost alternative to Ferroxcube™, Epcos™, TDK™ etc.. Many cores are held ex-stock and factory lead-times are much lower than the industry average.
