Today’s products, such as smartphones, have become smaller and thinner while still offering multi-functional performance. One example of multi-functional capability is a product that contains both near-field communications (NFC) and wireless charging technology. Thus, it is even more essential that noise is adequately suppressed in today’s electronic products. One method of suppressing noise is by using magnetic sheets.
TDK Corp. is one company that offers magnetic sheets for noise suppression. The company recently expanded its Flexield series by introducing the new IFM10M noise suppression sheets, which can be used in a number of products (see figure). According to Harvey Espinoza, director of product marketing, communications devices business group at TDK Corporation of America, “The magnetic sheets are used in various types of electronic devices, such as smartphones, tablets, notebooks, stylus pens, point-of-sale (POS) systems, and industrial terminals.”
