Nichicon Introduces New Series Of Layered Conductive Polymer Aluminum Capacitors

November 29, 2007 by Jeff Shepard

Nichicon Corp. has released a new line of molded conductive polymer capacitors called the "F11 series". The layered aluminum design of the F11 series is claimed to provide the ultra low ESR and ESL over a wide frequency range needed in today’s high performance LSI (Especially in PC CPU’s and GPU’s and in gaming equipment).

Ultra small applications such as graphics processors for PC’s demand components that are smaller but with higher performance. In the capacitor area, this means smaller size and lower overall impedance. For example, high performance LSI IC’s (CPU and GPU) need decoupling circuits with lower ESR and lower ESL over a wide frequency range. To meet this requirement designers have had to use dozens of capacitors, all of which may have different characteristics at various frequencies. According to the company, until now, the only way to overcome this was by using more capacitors even though the size reduction requirements of end applications demanded fewer parts. To meet this requirement, Nichicon released the "F11 series", which it states can replace the need for so many capacitors due to its ultra low ESR and ESL characteristics yet also provide greater performance.

The F11 series uses layered aluminum construction, conductive polymer electrolyte, and a unique three terminal design all in a molded package. This structure decreases the magnetic field and inductance at ultra high frequency so the part achieves what is described as excellent impedance characteristics over a wide frequency range. The company claims that the F11 series has large capacitance and ultra low ESR/ESL, and thus can be used to reduce the total number of capacitors now required using conventional capacitors.

The F11 presently has a voltage range of 2.5v to 6.3v and a capacitance range of 47 to 2400µf. The operating temperature range is -55 to +105C. Two sizes are presently available (F size (16.7 x 12.1 x2.5mm) and D size (8.5 x 5.3 x2.0mm).
