World’s smallest common-mode filter for high-speed interfacesFootprint 75 percent smaller than existing productsHigh 7.0 GHz cutoff frequencyThe number of complete cycles or vibrations per unit of time. Rate of alternation in an AC current. Expressed in cycles per second or hertz (Hz). TDK Corporation has developed the world’s smallest common-mode filter, which measures in at only 0.45 mm x 0.30 mm x 0.23 mm and is 75 percent smaller than current 0806 filters IEC. Besides its miniature dimensions, the new TCM0403S-350-2P thin-film common-mode filter offers excellent performance. With a high cutoff frequencyThe number of complete cycles or vibrations per unit of time. Rate of alternation in an AC current. Expressed in cycles per second or hertz (Hz). of 7.0 GHz the filter suppresses common-mode noise without distorting high-speed differential signals. It is thus compatible with various high-speed interfaces such as MIPI, USB 2.0, and USB 3.0. The excellent common-mode attenuation at 2.4 GHz improves the wireless LAN reception sensitivity in smartphones, conventional mobile phones and other compact portable devices. Mass production will begin in July 2012. The milestone in miniaturization was realized using TDK’s leading-edge thin-film patterning technology combined with compact, high-precision coil pattern and terminal formation processes. Thanks to its much smaller footprint, the new filter supports the high-densityA figure of merit usually expressed in Joules per cubic inch for capacitors mounting of electronic components and contributes to significant space-saving in electronic devices.  ...Read more

High-performance multilayer band pass filter in 1005Volume reduction of 75 percent compared to existing componentsInsertion height more than one third lower TDK Corporation has developed a multilayer band pass filter in size 1005 that is significantly smaller than the existing 1608 types. With its miniature dimensions of just 1.0 mm x 0.5 mm x 0.37 mm, the insertion height of the new DEA102450BT-1278A1 band pass filter has been reduced by more than a third and its volume by 75 percent. The filters are designed for the 2.4 GHz band, and are thus suitable for Bluetooth and wireless LAN implementation in smartphones, regular cell phones, and other mobile devices. They feature an outstanding insertion loss of just 2.5 dB and a high attenuation of at least 25 dB at 4.8 GHz to 5.0 GHz. Despite the component’s small form factor it offers a rated power as high as 27 dBm. Mass production has launched in April 2012. As smartphones and other mobile devices become ever smaller, lighter, faster, and capable of handling higher frequencies, their electronic components also must provide high performance in a compact, low-profile, lightweight package. TDK used its advanced thin-layer and micro-wiring technology to develop the new band pass filter with both miniature dimensions and excellent performance characteristics. Thanks to the use of a low-loss conductive material for the resonator the DEA102450BT-1278A1 also features high Q values. The new product is rated for an operating temperature range of -40 °C to +85 °C.  ...Read more
