Substituting solid tantalum and tantalum polymer

In general, MLCCs have lower ESR than either solid tantalum or tantalum polymer capacitors of the same voltage rating and capacitance values. For a typical 47 F, 6.3V 1206 capacitor, the maximum 100 kHz ESR levels would be something like this Solid tantalum ~ 0.9 Ω ;

An alternative to solid tantalum capacitors Hacker News

Mar 29, 2017The past three companies I've worked for that were doing circuit board design expressly forbid the use of tantalum capacitors because they are surface mounted (SMT) two-terminal parts that have polarity. In other words, tantalum caps have a and a terminal and are damaged when reverse voltage is applied.

Conductive Polymer Tantalum Solid Capacitors (POSCAP

Conductive Polymer Tantalum Solid Capacitors (POSCAP) POSCAP utilizes sintered Tantalum as an anode sytem and highly conductive polymer created with Panasonic's unique method as a cathode system. This enabled POSCAP to be thin, small and at the same time have low ESR (Equivalent Series Resistance) and superior high frequency characteristics.

Geoff's Projects Measuring Capacitor ESR

This means that the capacitor's ESR was approximately 0.3Ω (the capacitor under test was a 330F 50VW aluminium electrolytic). This method will work for values of ESR from 0.1Ω to greater than 10Ω. Alas, it is not very accurate but then the ESR of a capacitor is not a precise value anyway and I was only looking for an approximation.
