Capacitance and voltage – the BOM-fit check
The TAJR105K016ANJ carries a capacitance of 1 µF and a voltage rating of 16 V, per the order code itself — the '105' decodes to 1 µF and '016' to 16 V. That is the first and most important spec for a buyer matching a BOM line: if the board calls for a 1 µF, 16 V tantalum or specialty capacitor, this part number fits without a redesign.
