Environmental group seeks greater protection for USDA scientists
2015-03-28 02:41:08| Chemicals - Topix.net
An environmental activist group has filed a legal petition with the U.S. Department of Agriculture seeking new rules that would enhance job protection for government scientists whose research questions the safety of farm chemicals. The action filed on Thursday by the Public Employees for Environmental Responsibility, an advocacy group for local, state and federal researchers, came less than a week after a World Health Organization group found the active ingredient in Roundup, the world's best selling weed killer, is "probably carcinogenic to humans."

BiSy Single-Line ESD Protection Diode conserves board space.
2015-03-26 13:31:08| Industrial Newsroom - All News for Today
Supplied in 0.6 x 0.3 x 0.27 mm package, VBUS05B1-SD0 protects high-speed data lines and antennas in mobile devices against transient voltage signals. Leads length and package size minimizes inductance, allowing fast transients, such as an ESD strike, to be clamped with minimal overshoot/undershoot. Properties include 0.29 pF typ load capacitance (0.4 pF max), <0.1 µA max leakage current at 5.5 V working voltage, 8.8 V typ breakdown voltage at 1 mA, and 18 V max clamping voltage at 2.5 A.
