May 26, 2010 Weekly High Risk Electronic Components

Share

 

As of May 26, 2010, be on the lookout for the following high risk devices:

· Kemet T520V226M020ATE040, 100% failure - high ESR

· Texas Instruments OPA2541SM, 16% failure - clipped and clamped output

· ON Semiconductor NID6002NT4G, 100 failure - high drain-to-source leakage current

· Fairchild FDB2532, 5% failure - low gate threshhold voltage, Vgs(th), and high drain-to-source leakdage current (Idss)

· Nichicon PCF0J331MCL1GS, 100% failure - high ESR

· Analog Devices AD8310ARM, 100% failure - output is clamping to the supply and drawing current at no load to overheat the devices

· Texas Instruments TPS40009DGQR, 96% failure - unstable output and feedback voltages

· BS62LV4006-EIP55, 10% failure - bad protective diodes

· Texas Instruments OPA2343UA, 16% failure - no signal on both channels

Capacitor Requirements on the Rise Due to Shortage of Rare Earth Elements?

Capacitors, here we go again.....is it 1999 all over again? We were seeing so many new Kemet, Vishay and AVX requirements it made us wonder why. Then we found this article that might help explain:

Shortage of Rare Earth Elements Could Thwart Innovation
By Jeremy Hsu, TechNewsDaily Contributor

Share Silicon may represent one of Earth's more common elements, but it transformed Silicon Valley into a high-tech corridor and helped usher the world into the Information Age...Rare earth elements, called "rare earths" by those who use and study them, often prove irreplaceable in green technologies and high-tech consumer products.

Yet the world's production of rare minerals relies mainly upon China, and the Chinese government warned last year that its own rising demand will soon force it to stop exporting the precious elements.

"Countries and companies that have or plan to develop industries that need rare earth minerals to make products are concerned about China's growing consumption, which they fear will eliminate China's exports of rare earths," said W. David Menzie, chief of the international minerals section at the U.S. Geological Survey (USGS).
