Noise suppressing chip beads
23 October 2013, Circuit & System Protection

TDK has extended its MMZ portfolio of Gigaspira beads with the MMZ1005-V series, which reportedly features the world’s highest impedance peak frequency in the 2,5 GHz range. The EMC components enable simple and effective noise suppression of high-frequency signals above 2 GHz, as used for WLAN and LTE, for example.

The parts offer a high impedance of up to 3000 Ω at 2,5 GHz. They are available in IEC case size 1005 (EIA 0402) and measure a miniature 1,0 x 0,5 x 0,5 mm. Thanks to these features they are ideally suited for noise suppression in smartphones, tablet PCs and other mobile communication devices.

The elevated performance of the MMZ1005-V series was made possible thanks to the use of new ferrite material. Depending on type, the new beads offer a maximum DC resistance of between 0,9 Ω and 1,6 Ω and a rated current of 150 mA to 250 mA.
