The LED can
be used wherever there are large fluctuations in temperature and a large amount
of light is needed from a small area. The thermal coefficient of expansion
of the molding material precisely matches the coefficient of expansion of the boards,
and there is an ESD protective diode concealed in the molding. The high output
efficiency in the black package does not require additional reflectors. The
materials have been chosen so that even large fluctuations in temperature do
not have an adverse effect on reliability or on the life of the LED (approx.
50,000 hours). The Oslon LED
has a low thermal resistance of 6.5 K/W.
The Oslon Black Series has a lens with
a 90 degree beam angle and produces a typical brightness of 115 lm at an operating
current of 350 mA and a color temperature of 6500 K. By increasing the operating
current to 1 A, it is able to achieve a brightness of 250 lm. The LED uses a 1 mmÂ²
chip and is available in all colors, including warm white. The Oslon Black Series solder pad is
compatible with the other LEDs in the Oslon product family.
The LED is useful for signal lights, interior
lighting for refrigerators and lighting for train, planes, automobiles, and
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.
