ELECTRONICS: TT electronics IRC offers two series of low resistance metal alloy current sense chip resistors. Designated the ULR and LRMA Series, the resistors feature a metal strip construction capable of withstanding high temperatures and large currents.
The ULR and LRMA Series resistors are ideal for use in current sense circuits in power electronics and automotive systems.
The RoHS compliant and halogen free ULR and LRMA Series resistors feature_low TCRs (50, 75, and 100ppm/C) and inductance values. Resistance ranges from 0.5mΩ to 100mΩ, with power ratings from 1W to 3W, depending on device. The ULR Series resistors are offered in 1206, 2010 and 2512 chip sizes, while the LRMA Series devices are available in 0815, 1206 and 2512 chip packages.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
