As electronic products become smaller, increasingly complex and more energy efficient, passives components are changing. The trend is toward higher performance with less energy consumption. "The very latest market trends for passive electronic components continue to be primarily driven by end application requirements," says Craig Hunter, director of sales communications at AVX Corp. Those requirements can be very specific. "A very hot topic at the moment is the need to find a new source of energy. As a result, high temperature components which can be used in drill-down drilling equipment and sensors are in demand," says Hunter. "We've launched tantalum capacitors which can operate at 175C and ceramic capacitors with an X8R high temperature dielectric to meet this need."
LEDs are also going through a new evolution to meet the needs of end users as they become smaller, brighter and more energy efficient. There has also been a shift in LED use. While backlighting needs are still pervasive, LEDs are called upon more and more to provide illumination. The need for energy efficiency is also driving the LED market. The U.S. Dept. of Energy says LEDs will more than double the efficiency of lighting systems and thus reduce the nation's energy consumption by $98 billion over the next 20 years.
Capacitors are also going through a transformation. The spike in cell phone sales in recent years is just the beginning of the push for capacitor innovations. Portable devices with multiple functions are showing up in medical and industrial settings. That trend will continue to pressure capacitor manufacturers to produce, smaller, more durable capacitors.
As for the market for passive components, the automotive and medical industries will continue to show a greater appetite, as will handheld devices. The aerospace and medical equipment markets will become increasingly specialized. While these markets gobbled up commercial off-the-shelf (COTS) components in the past, they are now turning to high reliability products, since COTS components have shifted to lead-free production and most of the COTS suppliers have shut down their leaded production. Since the military and medical equipment markets insist on the high reliability of lead solder, they are now shifting to hi rel parts to get their lead.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
With LEDs dropping in price virtually every year, automakers have begun employing them, not only on luxury vehicles, but on entry-level models, as well.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
