TDK Co., Ltd. (President: Sakamoto Kenhiro) developed a series of magnetic beads MMZ1005-V (L: 1.0 × W: 0.5 × H: 0.5 mm) for signal transmission circuits that achieve the highest level of resistance in the industry. Mass production began in September 2013.

In a mobile communication device represented by a smartphone, communication frequency is becoming higher and higher due to the installation of WiFi, LTE, and the like. As a result, passive components including modules need to be able to cope with noise countermeasures at frequencies above 2 GHz.

The product achieves high impedance by using a new magnetic material that extends the peak impedance frequency to the 2.5 GHz band. Impedance values on the 2.5GHz to 3,000 (Ω) typ., Compared with previous products Gigaspira beads (MMZ1005-E series) to achieve approximately 2.5 times higher impedance value. In addition, even with high impedance in the high frequency band, it can contribute to noise countermeasures for mobile communication devices.

In addition to the standard products of the previous products (MMZ1005 series) and the wide-band Gigaspira products (MMZ1005-E series), together with this product, we will provide a richer lineup of noise countermeasure components for information transmission circuits.

main application

Mobile communication devices such as smartphones and tablet terminals are equipped with LTE and wireless LAN (IEEE802.11b/n) electronic devices for various countries.

main feature

The impedance peak frequency is extended to the 2.5 GHz band to support noise countermeasures in the high frequency band.
