Use this drop-down menu to jump to all the product news stories from the Spring 2008 issue of Murata Mail. CapacitorsUltra-small 01005 chip capacitor
Low ESR, low ESL and ultrasmall size; Murata introduces the GRM02 series of 01005 chip capacitors. During its long history Murata developed and established process control know-how to meet market requirements. The GRM02 series dimensions are 0.4 x 0.2 x0.2mm, making it suitable for any application where saving mounting space is a necessity. Because of its low ESR of less than 0.1A Ohms, this series can be used to improve circuit performance in high frequency applications such as mobile phones and PDAs, and communication modules. The GRM02 series is available in wide capacitance ranges of 0.1pF up to 100pF (C0G dielectric) or up to 10nF (X5R dielectric) and provides hight resistance to solder-leaching due to the Ni-barriered termination. Excellent pulse response and noise reduction due to the low impedance at high frequency.
Piezo TechnologyReduce and save
Murata has developed a series of ceramic resonators with built in load capacitors to reduce component count and save space in USB 2.0 controller IC driver circuits: the new CSTC-EXTseries. Measuring just 3.2 by 1.3 by 1.0mm it is extremely low profile. This series has been especially developed for USB circuitry and realises a very high total frequency stability of 420ppm comprised of aging ( 270ppm) and temperature characteristic ( 150ppm) thus making the parts suitable to replace more expensive quartz crystal devices. The CSTCE-XT series does not require any external load capacitors and is extremely price-competitive, saving money for customers switching from quartz. Ceramic resonators like these also benefit from quicker start up times and better shock resistance than their quartz counterparts. This series is available in the frequency range 24 to 27.2/30MHz and operating temperatures are 0 to 70ºC.
SensorsBanking technology by Murata: the pattern recognition sensor
Murata has released four new products in its BS05 series of magnetic pattern recognition sensors. We would like you to meet the BS05M1HFAL, BS05M1KFCA, BS05M1KFFA and BS05M1KFBB magneto-resistive sensors. The devices are suitable for detection of magnetic thread or magnetic ink, and enable simple and quick mounting. These parts retain around 70% of their output voltage at a 0.1mm gap between sensor and substrate, compared to just 4% for typical coil head sensors. Along with their stable frequency characteristic, which is independent of the scanning speed, this makes them suitable for high-speed processing devices that demand superior accuracy. The BS05M1HFAL is an 8-channel sensor with channel width of 3mm, while the BS05M1KFFA has 9 channels 10mm wide. Both have all their MR-channels mounted in a straight line. The BS05M1KFCA six-channel and BS05M1KFBB 13 channel sensors have 10mm channel widths with MR-elements offset in alternate directions to make a zig-zag style configuration. This ensures there is no physical gap between each channel, leading to a faultless detection of banknotes. These sensors are therefore targeted at high end machines that have high scanning speed and require high detection reliability.
CoilsHigh Q, High inductance
Chip inductors that maintain high Q of at least 35 in the FM band, whilst offering high inductance and small size? Yes, check Murata's LQW21H series. It enables designers working with FM circuits to miniaturise their designs without compromising on performance. This series is designed for any FM band application where board space is critical, for example, TV tuners for mobile devices. Available in compact 0805 packaging, the LQW21H series provides 0.47 to 2.2µH inductance. The 0.47µH part, LQW21HNR47J00, has a rated current of 160mA at 10MHz with a maximum 1.30 Ohm DC resistance. The highest inductance part in the series is the LQW21HN2R2J00, with inductance 2.2µH at 10MHz, rated current of 75mA and a DC resistance of 6.5 Ohms maximum. Minimum Q is 35 at 100MHz for all parts in the series, with typical figures above 50 at the same frequency.
EMI FiltersSmall size, great performance
Murata's miniaturisation is a sensation. To keep up with the industry's demands for miniaturisation, Murata has introduced the world's smallest ferrite beads. Designed for EMI filter applications in DC power lines, these components will help to reduce board space without compromising on performance. (f.i. the BLM02AG100SN1B). The latest addition to the EMIFIL family of chip ferrite beads, the BLM02 series is available in the tiny 01005 size (0.4 by 0.2 by 0.2 mm), the world's smallest. They are capable of wide frequency range attenuation, typically 30MHz to several hundred MHz. Impedance ranges from 10 to 120 Ohms, with rated currents between 200 and 500 mA. DC resistance is below 0.8 Ohms for the whole series. Other additions to the EMIFIL family include the BLM03A, BLM03B and BLM03P series of chip ferrite beads in 0201 packaging. BLM03A ferrite beads feature a high impedance line up of between 10 and 1000 Ohms. Rated currents are 100 to 500mA; DC resistance is 2.5 Ohms maximum. The BLM03B series is available with impedances between 10 and 240 Ohms and features low DC resistance of between 0.4 and 1.5 Ohms.
The BLM03P series features high rated currents up to 900mA. All these components are all available with an operating temperature range of -55 to +125°C
RFID TechnologyMurata Magic
Murata's tiny, easy to mount inductive-coupled RFID modules enable global product lifecycle tracking without RF expertise; the LXMS31series. Murata has developed a tiny RFID module, called MAGICSTRAP™, that enables product lifecycle tracking using any global frequency whilst minimising the amount RF expertise required to implement an RFID solution. The manufacturing industry is being asked to manage product lifecycle more precisely and efficiently, in part due to legislation on the disposal of home electronic equipment. Systems for tracking a product throughout its lifecycle focus on reading an dwriting information such as production process history from an ID in or on the product. Barcodes are the current standard for individual identification of the products, but since they cannot accept new information, RFIDs have come into the spotlight as a technology that can resolve the shortcomings of barcode-based systems. Murata's MAGICSTRAP™ RFID module combines the latest in ceramic materials with a breakthrough in ceramic module and inductive coupling technology to produce a very easy to mount module. MAGICSTRAP™, otherwise known as the LXMS31 series, comprises Murata's LTCC (low temperature co-fired ceramic) substrate, plus RF IC and packaging. Murata's strengths in multi-layer ceramic technology have allowed the company to embed all the necessary RF circuitry, including antenna filters, matching circuitry and 10kV ESD protection, within the LTCC substrate of the module. The RF IC is then mounted on top. The overall package dimensions are 3.2 x 1.6 x 0.7mm. The module's internal circuitry is connected to the antenna pattern via inductive coupling. There are therefore no connection pads on the base of the module, instead the module is simply mounted using ordinary adhesive. Compared to competing products which require micron accuracy when mounting, for MAGICSTRAP™, millimeter accuracy is sufficient. Further, MAGICSTRAP™ exhibits stable performance even when mounted on materials which have a capacitance, like polypropylene. matching The module's embedded wideband antenna circuit, plus a single wideband antenna (for which Murata will provide a reference design), allow MAGICSTRAP™ to be readable over the band 800-1000MHz at a distance of 5m. This means the same module and antenna pattern can be used worldwide (in Europe, the US and Japan), saving cost and inventory for manufacturers.
