TAJ part numbers encode series, case size, capacitance, tolerance, voltage, packaging and suffix in seven fields. A field-by-field decoder with capacitance, voltage and case-size tables, plus the mistakes that cause wrong orders.
The two technologies fail in completely different ways. A parameter-by-parameter comparison, the middle ground of polymer and hybrid aluminium, and a practical selection order for deciding between them.
Decoupling, DC-DC filtering, energy hold-up, AC coupling and harsh-environment designs - where tantalum capacitors earn their place, where they should not be used, and the derating and inrush rules that keep them reliable.
A step-by-step look at tantalum capacitor manufacturing - powder production, vacuum sintering, anodisation, and MnO2 versus conductive polymer cathodes - and how each process step determines the electrical limits you read on the datasheet.
