These high performance ICs require high performance passive components to support continuous reliable operation. KEMET T520 and T521 polymer capacitors provide high capacitance with a wide operational temperature range and low ESR. When lower ESR is needed, X7R and C0G ceramic capacitors can be used in parallel. Combining daughter cards into a single design often places height limitations on components. KEMET chip style capacitors can assist with combining more components in a smaller footprint. Solid state capacitor technologies such as polymer aluminum, polymer tantalum, and multilayer ceramic are best suited for the long term reliability needs for network communication equipment. 48 V 12 V/19 V/24 V DC/DC Converter 0.9 V/1.5 V/1.8 V/2.5 V/ 3.3 V/5 V FPGA ASIC DSP DC/DC Converter Feature Highlights Low Profile For more information, samples and engineering kits, please visit us at www.kemet.com or call 1.877.myKEMET.
