Shenzhen Huaqiang North electronic products rose by Japan earthquake
After the big earthquakes in Japan, inter-industry of "Huaqiang North chip prices rose 20%" market predictions has been verified. Mr. Wu to the "Daily Economic News" reporters, according to ic components index the center statistics, since the earthquake has been integrated Huaqiang North all electronic products, with gains of more than 20%. But with Japan's post-disaster reconstruction work, the number of affected vendors have begun to resume production. Earlier, the world's second largest supplier of 300 mm wafers Shin-Etsu Chemical announced the closure of four after the earthquake has two factories have resumed production.
DRAM memory chip maker Elpida also said, in northeastern Japan, a chip testing and packaging plant has resumed production, which for the market, is a very positive signal.
In addition, relative to other countries and regions in Asia, the Japanese electronic components industry on preventive measures to be fully earthquake much better seismic performance of their plant, in addition to the destruction of the earthquake only a small part of the factory, so the earthquake did not give their cause fatal damage to the electronic component industry. Medium to long term, and will not have a material impact on its industry chain.

About Ic components LM117/LM317A/LM317 Performance index
Ic components LM117/LM317A/LM317 many aspects performance,now lists some
Besides replacing fixed regulators, the electronic components LM117 is useful in a wide variety of other applications. Since the regulator is “floating” and sees only the input-to-output differential voltage,voltage,supplies of several hundred volts can be regulated as
long as the maximum input to output differential is not exceeded,i.e., avoid short-circuiting the output.
Also, it makes an especially simple adjustable switching regulator, a programmable output regulator, or by connecting a fixed resistor between the adjustment pin and output, the
electronic component LM317 can be used as a precision current regulator. Supplies with electronic shutdown can be achieved by clamping the adjustment terminal to ground which programs the output
to 1.2V where most loads draw little current.
For applications requiring greater output current, see LM150 series (3A) and LM138 series (5A) data sheets. For the negative complement, see electronic component LM137 series data sheet.

Introduction to the function about Resistor
Resistor is One of the electronic components,here the function about Resistor:
1.A resistor provides resistance to the current, that is, it controls the amount of current measured in amps. The current in amps is dependent on the voltage.
2.Resistance is measured in Ohms. The first coloured band represents the first significant figure, the second coloured band represents the second significant figure and the third coloured band represents the number of zeros following the first 2 figures. A fourth colour may be used to indicate the percent tolerance of the resistor.
