alum vs tant2

The graphs on this slide further illustrate the superior capacitance retention of the hermetic aluminum electrolytic technology. The first graph (top left) shows capacitance change with frequency while temperature is held constant at -55°C. There is a lowering effect of capacitance as frequency is increased. The second graph shows capacitance roll-off with frequency of four wet tantalum capacitors in parallel. The slope of the capacitance drop for the wet tantalum bank is much steeper. The third graph (bottom) is the ratio of the capacitance curves, i.e. the capacitance measured on one MLSH divided by the capacitance of the parallel bank of four wet tantalums across the entire frequency range. Where the ratio exceeds one (1), the MLSH solution has higher capacitance than the bank of four wet tantalum caps. Between the range of 100 Hz through 10 kHz, the single MLSH capacitance exceeds that of the four wet tantalum caps in parallel. At 1 kHz, the MLSH capacitance is twice that of the parallel bank of four wet tantalum caps.
