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...

In capacitor research, much effort has been focused on development of high energy density devices. It’s easy to see why. The need for efficient, high-performance materials for electrical energy storage has been growing in parallel with the ever-increasing demand for electrical energy in mobile applications. Along the way dielectric capacitors, which comprise an insulating material sandwiched between two conducting metal plates, have become key components of portable electronics, computing systems and electric vehicles. One hurdle preventing even faster growth is that in contrast to batteries, ...

Forecast changes in temperature requirements in defense and downhole pump electronics have challenged the capacitor industry to produce new products that can operate in exceedingly higher temperatures for longer time periods of time. For years the operating temperature and available capacitance values of competing high temperature dielectrics was limited to about 200 °C and picofarad levels of capacitance. There was also the added problem of limited volumetric efficiency of the capacitors being consumed. Therefore, the trend has been to increase the operating temperature of the capacitors...

The fiscal year ending March 31, 2016, has proven to be an unusual economic year in the history of tracking the global capacitor, resistor and inductor markets worldwide. The market environment is succumbing to the impact of forces that are both internal and external to the supply chain and almost every company in the world selling electronic components took a beating in the markets in the last fiscal quarter, unless you were selling to specific manufacturers in China who in turn were building specific types of smartphones. The real crack in the armor came mid-March 2016 when a key industry ex...

Introduction to Microwave and Millimeter Wave Capacitor Markets    There are many specific sub-segments of the global ceramic capacitor market. It is possible to look at the market from the perspective of high voltage, high frequency, high temperature; or specific harsh environment component operation. Paumanok takes a granular approach to these segments because they are the most profitable, the most fragmented and the most difficult to understand, not only for those actively participating but especially for those mainstream ceramic capacitor manufacturers wishing to enter advan...

The annual Applied Power Electronics Conference (APEC) and exposition was held at the Long Beach (CA) Convention & Entertainment Center last month. As at the last few APECs, Wide Bandgap (WBG) materials GaN and SiC were the subject of many of the technical papers (by one count there were over 100 technical papers and presentations that referenced GaN) presented at the conference. By way of review, among the advantages WBG semiconductors have over Si in power electronics are lower losses for higher efficiency, higher switching frequencies, the ability to withstand higher operating temperatu...

The three-month rolling averages of North American printed circuit board (PCB) and semiconductor sales continued their decline in January 2016, as electronics manufacturing services (EMS) sales remained flat. U.S. new orders for electronic equipment ticked up slightly in January after a dip in December reflecting the slowdown in the fourth quarter of 2015.U.S. new orders for electronic products tend to lead sales by one to two months. Another leading indicator is IPC’s PCB book-to-bill ratio, which normally leads sales by three to six months. Ratios were positive in the first 10 months of 2015...
