2 Installation Precautions(1) Do Not Use The Capacitor That Has Been Energized On The Device. Except For Capacitors That Are Removed For Periodic Inspection During Electrical Inspection, They Cannot Be Used Again.(2) Even If The Capacitor Is Discharged, A Voltage (Re-Flash Voltage) May Be Generated Between The Terminals. In This Case, Discharge Through A 1kΩ Resistor.(3) The Leakage Current Of Capacitors Stored For More Than Half A Year May Increase. In This Case, Perform Voltage Processing With A 1kΩ Resistor.(4) After Confirming The Rated Value (Electrostatic Capacity And Voltage) Of The Capacitor, Install It.(5) After Confirming The Polarity Of The Capacitor, Install It.(6) Do Not Drop The Capacitor To The Ground. Do Not Use A Capacitor That Has Fallen Behind.(7) Do Not Deform The Capac...

The low cost and generally competitive quality of printed circuit boards (PCBs) produced in China has tempted ever more electronics manufacturers worldwide to offshore their PCB sourcing to that country over the past decade.South Africa has been far from immune from this phenomenon, and nor will the country be exempt from an impending copper shortage, warns local supplier Cirtech EDA’s business development director, Nechan Naicker.Gaining a global perspectiveCirtech EDA’s existence dates back to early 2015, when local PCB manufacturer Cirtech joined forces with the PCB sourcing arm of EDA Tech...

Are you thinking of using a rigid/flex format for a PCB? If so, the first and most obvious answer to the question ‘why?’ is to make use of the flexibility and to permit movement between two conventional boards – even if the movement is limited to providing vibration tolerance.Flex circuits that actually flex in regular use can, however, be considered a special case; very often, the intent is to provide an efficient interconnect between two boards that do not lie in the same plane. In such cases, the flexible part may only flex during final assembly of the product and never do so again.Flex-rig...

It may seem something of an understatement, but Phil Mayo, director of sales for Altium UK, believes: “The PCB is important.” And perhaps that’s one reason why the workshop and conference sessions addressing PCB design at last year’s Electronics Design Show (EDS) attracted record numbers of engineers.In his workshop presentation, Mayo noted: “For decades, the humble PCB has been the cornerstone of all electronic products. Today, perceptions of the PCB range from a simple interconnect medium to a fundamental component of a complex electronic system. Regardless of the perception, the reality is ...

Capacitors are like batteries in that they store and release energy. However, capacitors use separated electrical charges, rather than chemical reactions, to store energy. The charged particles enable energy to be stored and released very quickly. Imagine an electric vehicle that can accelerate from zero to 60 miles per hour at the same rate as a gasoline-powered sports car. There are no batteries that can power that type of acceleration because they release their energy too slowly. Capacitors, however, could be up to the job -- if they contained the right materials.  NC State physicist D...

Oct. 21, 2015, was the day that Doc Brown and Marty McFly landed in the future in their DeLorean, with time travel made possible by a "flux capacitor."  While the flux capacitor still conjures sci-fi images, capacitors are now key components of portable electronics, computing systems and electric vehicles.  In contrast to batteries, which offer high storage capacity but slow delivery of energy, capacitors provide fast delivery but poor storage capacity.  A great deal of effort has been devoted to improving this feature -- known asenergy density -- of dielectric ca...

Introduction: Product and Market OverviewPassive electronic components considered as specialty parts are high dollar, low volume products whose pricing is secondary to quality. These products have the highest operating margins and represent the smaller percentage of global passive component revenues, accounting for about 13% of global capacitor, resistor and inductor revenues in fiscal year 2015.In this MarketEYE article, we take a closer look at specialty passive components that are consumed in value-added and application specific market segments on a global basis. Such components are general...
