TDK Corporation recently expanded its MMZ portfolio of Gigaspira beads with the introduction of the MMZ1005-V series. The company claims that its latest offering features the world's highest impedance peak frequency in the 2.5GHz range. The new EMC components enable simple and effective noise suppression of high-frequency signals above 2GHz.

The new Gigaspira beads offer a high impedance of up to 3000次 at 2.5GHz. The types are available in IEC case size 1005 (EIA 0402) and measure a miniature 1.0x0.5x0.5mm. Thanks to these features the MMZ1005-V Gigaspira beads are ideally suited for noise suppression in smartphones, tablet PCs and other mobile communication devices. Production of the new MMZ1005-V Gigaspira beads begins in September 2013.

The benchmark performance of the TDK MMZ1005-V series was made possible with the use of new ferrite material. Depending on type, the new beads offer a maximum DC resistance of between 0.9次 and 1.6次 and a rated current of 150mA to 250mA. With the addition of the new series to the standard MMZ1005 series and the wideband MMZ1005-E Gigaspira series, TDK's line-up of chip beads now covers an even wider range of requirements for noise suppression in signal lines.
