The new OSTAR Compact LED from OSRAM Opto Semiconductors is accommodated in the same 3.9 x 3.6mm
package size as the previous version, enabling small projectors to be designed
with higher brightness without increasing their size. Instead of 4A, the new
LED can now be pulsed up to 6A, achieving 350 lm in amber, 600lm in green and
165 lm in blue in pulsed mode (typically 120Hz, 2 ms, Ts= 25C).
Thanks to a new packaging material, its thermal resistance has been reduced to
3K/W, compared to 6K/W for the previous version, allowing heat to be dissipated
performance of the high-power OSTAR Compact LED is achieved with a 2 mm² chip
that benefits from improved epitaxial processes and a more even power
The new LED with the higher current capability extends
the portfolio of OSTAR Compact LEDs for projection applications. The OSTAR
portfolio includes LEDs with chips having sizes of 750 x 750µm and 1 x 1mm
available in all colors.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
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.
