Tiny Inductors from TDK for True Stereo in Cable-Free Earbuds

True Wireless Stereo devices deliver stereo sound through completely cable-free earbuds. They are finding increasing application with smartphones, smartwatches, other wearables and portable players, driving up demand from electronics manufacturers for components to enable them. 

One component maker targeting the domain is TDK which has introduced a new line of inductors that use its unique magnetic shield structure to reduce magnetic flux leakage. The company says that it plans to continue to broaden its lineup of inductor products with higher efficiency and smaller sizes to serve the growing market. 

In addition to an impressive rated current of 500 mA, the PLEA67 series of inductors also boasts one of the industry’s smallest external sizes, measuring at 1.0 mm x 0.6 mm x 0.7 mm. The compact size facilitates space saving in circuit board design and helps reduce the weight of earphones, providing users with mobility comfort. 

Their magnetic shield structure reduces magnetic flux leakage to pave the way for high density implementation. The company says that its original structure design and newly developed materials are used in its thin-film process to achieve the attributes. For more info, see www.tdk.com
