The MMZ1005-E devices offer high-performance noise filtering capabilities across a wide range of high frequencies. In systems that currently employ multiple narrowband inductors to cover a broad frequency range, the MMZ1005-E can provide the same function on a single chip, thus reducing the number of components and the board footprint.
The three inductors—MMZ1005S 182E, MMZ1005A 182E, and MMZ1005A 222E—offer a high impedance of 1800 Ω–2200 Ω at 100 MHz and 1800 Ω–3000 Ω at 1 GHz. The MMZ1005S 182E and MMZ1005A 182E have a current rating of 200 mA, while the MMZ1005A 222E has a current rating of 150 mA.
Current trends in mobile devices, such as mobile phones, include the incorporation of more advanced features like digital terrestrial and FM broadcasting, as well as GPS, in addition to standard voice communication functions. Each of these advanced features requires a different signal when used. If radiated noise affects the receiving antenna or units with high-frequency circuitry, reception sensitivity can be compromised. Therefore, it is necessary to eliminate noise from high-density circuitry and isolate each signal. As mobile devices become smaller and thinner, there is a growing demand for space-saving component assemblies and smaller components.
By utilizing a novel multilayer structure and ferrite material technologies, TDK has succeeded in increasing the impedance of its pearl chip inductors, which have been added to the existing range of products suitable for noise elimination across a broad band within the gigahertz range. Including the new devices, the TDK Gigaspira bead range (MMZ1005-E) consists of a total of eight types of two materials, allowing users to select the product that best suits their needs.
