Epcos has added the SpeedPower II and III series to its SpeedPower range of tantalum chip capacitors because more and more applications call for diversification of equivalent series resistance (ESR) as well as of capacitance and rated voltage in capacitors. ESR is often the critical factor for the entire design.
The SpeedPower II series extends the range of capacitors in case sizes B to E with several gradations in the ESR limits. This series also introduces tantalum capacitors in case size A. The SpeedPower III series features an optimised anode design with a larger surface area for even lower ESR. Both series cover the ESR range from 40 mΩ to 15 Ω at rated voltages of 2,5 to 50 V in case sizes A to E.
If the low-ESR types are used, connection of capacitors in parallel can be avoided. This leads to more compact designs, enhanced reliability and reduced placement costs. Typical applications will be found in telecoms, automotive, consumer and industrial electronics, data systems, and all applications where space is at a premium.
