SMD NTC Thermistors offer stability with low R25 value variation.
2014-01-30 14:33:45| Industrial Newsroom - All News for Today
Providing precise measurements, NTCS....E3...SMT series experiences ±0.5% max variation in initial electrical resistance values at +25°C (R25) after 10,000 hr of operation over the full -40 to +125°C range. Non-standard R25 values are adapted to resistivity of thermistors' stable ceramic material and case dimensions, preserving original electrical properties throughout lifetime. Supplied in 0402, 0603, and 0805 case sizes, RoHS-compliant thermistors offer R25 values from 100–210 kΩ.

New Analogue Compensated TCXO From IQD Delivers A Frequency Stability Down To 0.28ppm
2014-01-28 05:58:08| rfglobalnet News Articles
Portable instrumentation equipment and communications systems (fixed and mobile) frequently require a high stability oscillator but don’t have either the physical space for or power to drive an Oven Controlled Crystal Oscillator (OCXO). IQD's latest TCXO launching at Embedded World 2014 provides a practical alternative and is designed specifically for such applications.

Population Stability Key To Species' Response To Climate Change
2014-01-06 11:25:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: Species populations have to become stable in order for those creatures to expand their geographical ranges in response to global warming, according to new research published Sunday in the online edition of the journal Nature Climate Change. In the new study, researchers from the University of Yorks Department of Biology, Butterfly Conservation and the Natural Environment Research Council (NERC) Centre for Ecology and Hydrology report that the climate in the UK has warmed over the past 40 years....
