Higher performance SSDs use larger buffers, which are volatile. When power is lost, they require a large bank of energy to finish flushing out those buffers. The long life at high temperature requirements (up to 85°C and occasionally higher) drive the need for solid capacitor technologies such as KEMET’s T545 High Energy Polymer. These capacitors offer the highest energy densities with profile heights as low as 1.2 mm. With virtually no wearout mechanism, the T545 Series offers long operational life at temperatures beyond 70°C. Circuit Conditions • NAND flash memory < 70°C • Component height limitations: 1.2 – 2.0 mm • Input voltage/current of 5 VDC or 12 VDC/1 – 2 A • Drive start-up time in ms • Redundancy in capacitance bank 12 V 5V Input DC/DC converter 5 V – 12 V DC/DC converter 12 V – 4.2 V Multi-channel DC/DC converter Capacitor Requirements • High energy density • Low profile • Long life at < 70°C For more information, samples and engineering kits, please visit us at www.kemet.com or call 1.877.myKEMET.
