Linear Technology Corporation introduces the LTC4366, an overvoltage protection controller for electronic systems. Operating from 9V to greater than 500V, the LTC4366 floating surge stopper utilizes an adjustable floating topology to enable very high voltage operation independent of the voltage rating of the LTC4366’s internal circuitry. Two internal shunt regulators coupled … [Read more...]
Miniaturized High-Voltage Film Capacitors
TDK-EPC has extended its range of EPCOS MKP film capacitors with the new B32671L8* and B32672L9* series. These high-voltage (2000 V DC) capacitors are now available with greatly reduced lead spacing (LS) from 10 mm. Previously, the smallest LS was 15 mm. In addition, the voltage of the LS 15 types has been increased from 700 to 900 V AC.The new film capacitors are particularly … [Read more...]

EMI Microwave Absorber Application Note
Laird Technologies, Inc. has published a new application note, "Q-Zorb™ Microwave Absorbers for Collision Avoidance System Applications."The application note examines how with the rise of wireless electronics and the movement to higher frequencies, microwave absorbers or "noise suppression sheets" (NSS) are now used to reduce electromagnetic interference (EMI) inside collision … [Read more...]
Researchers Quantify the Friction of Graphene
Researchers at the National Institute of Standards and Technology believe that stacking graphene, a sheet of carbon only one atom thick, can make it more slippery. Graphene slows down any object sliding over its surface and is able to be “folded, rolled or stacked” and is strong with unusual electronic and optical characteristics. This material can be used in “applications … [Read more...]

Mexico’s Drug Cartels Use Encrypted DIY Radio Network
To avoid discovery, Mexican drug cartels have been using encrypted DIY radio networks, in nearly all 31 Mexican states, since 2006. Their communication devices are “‘professional-grade’ radio antennas, signal relays and simple handheld radios that ‘cost millions of dollars.’” Mexican authorities have not been successful in stopping their wireless communication. The Zetas, one … [Read more...]
Researchers Think Turin Shroud Imprints are from EM Energy
A team of experts in Enea, the National Agency for New Technologies and Energy say that the images of a crucified, bearded man on the Shroud of Turin could not “be reproduced by modern scientific techniques.” They believe that images were created by “some form of electromagnetic energy (such as a flash of light at short wavelength).” Their findings “contradicted carbon-dating … [Read more...]
