Overview
As network communication speeds increase, so do the demands of the ASICs found in the
equipment supporting the infrastructure. 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.
