Broad interest sparks AO-CAP product line expansion

14 August 2002 Passive Components

Citing broad market interest in its AO-CAP aluminium polymer capacitor, and a growing interest in lower voltage devices, KEMET Electronics recently expanded the AO-CAP line to include larger capacitance devices and extended voltage ranges. Introduced in September 2001 with distributor partner TTI, the new product quickly reached the design tables of a broad range of customers in a wide range of industries. Consequently, KEMET went back to the drawing board to design production equipment to produce AO-CAPs for wider requirements.

KEMET's initial AO-CAP thrust was in the 6 V and 4 V devices, in D and V case sizes with capacitance in the 47-220 µF range. However, requests for higher capacitance values, X case size devices and 2 V AO-CAPs have been increasing, causing KEMET to move forward with plans to produce these additional devices.

John Boan, KEMET AO-CAP Product manager noted, "Within a month of the product launch we had many sample orders for the six initial values and sample requests for six additional values. TTI has filled all those orders and requests, and KEMET is further broadening the AO-CAP line to include devices with higher capacitance and devices with lower voltages. We have noticed an industry trend migrating toward lower voltages with these extremely low ESR devices. These capacitors will help extend battery life per charge, and that is a big deal. Based on the positive reception of the AO-CAP, KEMET is forging ahead to expand production capacity, despite the current slow market conditions."

"Engineers who have tried the new KEMET aluminium polymer AO-CAP capacitor are very enthusiastic about its attributes, particularly the improvement in capacitance retention and the product's considerably lower ESR," Boan also noted.

Desire to extend battery life along with the continued miniaturisation is driving the lower voltage/lower ESR requirements. At the same time, many telecom and networking applications are calling for higher capacitance AO-CAP devices, so KEMET is continuing to develop increased capacitance AO-CAP devices.
