Ceramic Capacitors GRM188R71H104KA93D

Murata GRM General Purpose Ceramic Capacitors are high dielectric constant type capacitors, in a smaller size with a higher capacitance value. The GRM ceramic capacitors are available in C0G temperature coefficients and offer no polarity. These capacitors have a higher resistance of solder-leaching due to the Ni-barrier termination (applicable for reflow-soldering and flow-soldering). The GRM capacitors offer high capacitance and high operating voltage levels (up to 3.15kV). The GRM ceramic capacitors are ideal for use on diode-snubber circuits for switching power supplies and as a primary-secondary coupling for DC-DC converters.

Huawei recently announced that it will build its first European 5G factory in France. On the 4th, Huawei again emphasized its willingness to build a factory, saying that no matter whether the French government finally decides to use Huawei products in 5G network construction, it will spend 200 million euros to set up factories here.

Hong Kong News reported that Zhang Minggang, deputy general manager of Huawei's French market, said that no matter whether the French government decides to use Huawei's 5G network, Huawei will still promote the establishment of factories. The establishment of a 5G factory in France is part of Huawei's overall strategy. This factory will initially invest 200 million euros, which is Huawei's first 5G factory in Europe.

Microsoft announced on Wednesday that the company may not be able to meet its personal computer business revenue target due to a supply chain disruption due to the outbreak of a new coronavirus. Affected by this, investors are waiting and seeing the prospects of the semiconductor giants-Intel and AMD. According to Wccftech, Microsoft said in a statement on Wednesday: "Although we see strong market demand for Windows-which is also in line with our expectations, our supply chain is back to normal operations slower than the second-quarter earnings call Expectations at the meeting. Affected by this, the capacity recovery of Windows OEM and Surface products will also be slower than expected, and we expect that in the third quarter of fiscal 2020, the previous Revenue Guidance goals for the personal computer business may not be completed.

Relevant analysts also noted that Microsoft's personal computer business revenue guidance value is between $ 10.75 billion and $ 11.15 billion. The uncertainty of this value exceeds previous years, which also reflects the uncertainty brought to the market by the current outbreak of new coronaviruses. It should also be noted that Microsoft's Windows OEM revenue comes from the sale of Windows licenses for commercial and non-commercial PCs.

The news is just one of several such announcements that Microsoft has been updating recently. Last week, Apple announced that it was also unable to meet its quarterly revenue forecast due to the drop in demand in the Chinese market caused by the interruption of the supply chain and the outbreak of the new coronavirus. Apple originally expected its second-quarter net sales to be between $ 63 billion and $ 67 billion. In addition, Apple has not updated its quarterly revenue forecast so far. As the second largest personal computer manufacturer after Lenovo, HP also announced this week that the outbreak of the new coronavirus simultaneously and greatly affected China's supply system and sales market, which will bring its revenue and profits negative impacts.

HP Chief Financial Officer Steve Fieler said during an earnings call earlier this week: "Given some of the issues we will see in the second quarter, the outbreak of the new coronavirus may eventually be delayed Windows 10 update time. "Similarly, Lenovo CEO Yang Yuanqing also said during a conference call this week that although most of its factories in China have resumed work, the supply situation this quarter is still quite grim. Nvidia has estimated the impact of this new coronavirus on its revenue and noted that actual revenue may be reduced by $ 100 million compared to previous revenue guidance data. According to the company, with the expansion of quarantine and the closure of some companies, the epidemic may also affect consumer consumption patterns.

The development of semiconductor devices can be roughly divided into three stages. The fifties was a discrete component stage. The 1960s was the stage of integrated circuits, and the early 1970s was the stage of large-scale integrated circuits. At present, it is committed to the research of VLSI technology, which is an important technological development mark from the late 1970s to the 1980s.

The so-called integrated circuit is to make transistors, diodes, resistors, capacitors and other components using planar technology on a semiconductor single wafer (usually a silicon wafer), and use special structures to isolate them electrically from each other, and then connect them to each other to form a In terms of scale. The micro-structure integrated circuit is divided into four types: small, medium, large, and super large. There is no strict boundary between them. Generally speaking, the scale below 100 components is small, and the scale from 100 to 1000 components is medium.

1000 to 10,000 components are large-scale, and more than tens of thousands of components can be called very large-scale. The development of computers is much earlier than that of semiconductors. Starting from mechanical computers, they have gone through the stage of tube computers. When transistors were born, they were quickly used by electronic computers. With the emergence of integrated circuits, the development of electronic computers has become even more powerful and has become more and more unusual: the performance is getting higher and faster, the speed is getting faster, the power consumption is getting less and less, and the size is getting smaller and smaller. The entire circuit of the early vacuum tube electronic computer weighing 30 tons can now be made entirely on a silicon wafer with a length of 4 mm. Encapsulated is much smaller than a matchbox. The 30-ton behemoth has changed and shrank to less than the size of a matchbox. It must be said that it is a miracle in the technical world! In this miraculous change, large-scale integrated circuits have played a major role.

Due to the high concentration of components and circuits in large-scale integrated circuits, the entire circuit is greatly reduced, and the number of lead-outs and solder joints is also greatly reduced. Using it to assemble electronic equipment, its assembly density can be increased by a hundred times or even hundreds of times over transistors, and the stable working time of the device can also be increased by hundreds of times. Therefore, it occupies a very important position in military communications equipment, missiles, radar, artificial satellites, and various remote control, telemetry and other military equipment. Particularly worth mentioning is the application of large-scale integrated circuits in electronic computers. With the advent of large-scale integrated circuits, electronic computers have been miniaturized. The emergence and use of a large number of microcomputers has played an increasingly important role in improving the efficiency of the production sector.

At present, large-scale integrated circuits are in the ascendant, and circuit forms and process methods are constantly developing. What level of integration technology will be reached in 1985 and what level will it reach in 2000? It is estimated that the integration level will reach 1 million components in 1985. That is to say, it is not long before a medium-sized computer is housed in a silicon chip, so-called "single-chip". Due to the development of integrated circuits, by the year 2000, large-screen flat-screen stereo televisions will appear; light-guided television phones such as those facing them will also appear. Various vehicles equipped with radar and computer automatic control system will effectively prevent accidents. Computer-managed medical records will effectively monitor the health of hundreds of millions of people. Robots equipped with electronic computers will perform various tasks efficiently.
