Development of Ultra-low 7mΩ ESR

 NEC TOKIN Corporation (President: Yuichi Haneta; Head office: Sendai, Japan) has developed the new "PS/G" series "NeoCapacitor," a conductive polymer tantalum capacitor.  As a highly demanded ultra-low ESR decoupling capacitor, it is a perfect response to the voltage variation of CPUs.

 The move in personal computers from desktop to laptop has spurred trends toward integrating capacitors on to chips (from aluminum electrolytic capacitors to tantalum polymer and aluminum polymer capacitors) and further lowering profiles (from 4mm to 3mm to 2mm).  In addition, there has been a significant increase in requests to reduce the ESR in decoupling (bypass) capacitors, which are used in voltage variation measures through increased CPU speed, decreased drive voltage and lowered power consumption.  NEC TOKIN had initially responded with its lower ESR PS/L series, however, due to requests for a reduction in ESR to within a single digit, we launched the new PS/G series.

In the PS/G series, we were successful in lowering the ESR by 25 - 40 % through working on the device structure while maintaining the material, dimensions and other elements of the previous product.  The initial lineup includes the D Case (7.3x4.3x2.8mm) with a rated voltage of 2.5V, electrostatic capacitance of 330~470μF and the industry’s lowest ESR of 7mΩ.  NEC TOKIN is now moving forward in making additional reductions in ESR (5mΩ, as of the first half of 2004) and profile (V Case: 7.3x4.3mm, height 2.0mm max).

  Production is scheduled to start in January 2004 at both NEC TOKIN Toyama (Nyuzen, Shimo-niikawa County, Toyama Prefecture) and NEC TOKIN Electronics (Thailand) Co., Ltd. (Pathumthani, Thailand).  The initial production scale will be 5,000,000 pieces per month, with increases depending on demand.
