If your are looking for a super small capacitor.. contact us

Recently I got an email from CAP-XX Ultracapacitors talking about their latest ultracapacitor (also called supercap)  that will be used to enhance music phone audio quality and power. Cap-XX UltracapacitorSupercapacitors resolve current battery limitations enabling smaller, more functional devices.

Power demands on batteries are enormous as consumers push for smaller electronic devices with more and  functionality. Supercapacitors bridge the gap between the power demanded, and that available from batteries.

Supercapacitors provide power bursts for peak power events – wireless transmission, digital photos and video, GPS – then recharge from a battery. Designers can size the battery and power circuitry to cover average power consumption, instead of peak loads, saving space and cost.

Large cylindrical, and small, very-high-resistance, “button cell” type supercapacitors have been available for some time, but are not suited to mobile applications.

CAP-XX supercapacitors offer very high capacitance (0.09F - 2.4F) and very low ESR ( 20 - 100 milliohms) in a flat, and prismatic package that fits easily in portable electronic designs.

CAP-XX supercapacitors are thin enough (1 to 3 mm) to fit into a mobile phone without design modifications; and are available in dual-cell (up to 5.5V) or single-cell (2.5V) configurations of 28 x 17 mm or 39 x 17 mm. These support longer run-times in portable electronic devices and enable functions that were previously impossible.

CAP-XX BriteFlash Power Architecture for LED Flash Camera Phones

To address imaging applications such as 2+ megapixel-resolution camera-phones, CAP-XX’s supercapacitor-based BriteFlash power architecture delivers the pulse power to drive high power LEDs to full light intensity.   BriteFlash was launched in March 2006 and features a dual-cell, 0.55-farad, 50-milliohm GS206 supercapacitor to deliver 15 watts to the LEDs, versus 1 – 2 watts without a supercapacitor, yielding a 3-meter flash. The supercapacitor needs only a 250-mA charge current for the 2-second between-flash recovery period, and it’s ready to go again.
