What the temperature range tells you about deployment
The TAJY337K002RNJ: The molded case and 300 mOhm ESR mean it can sit on a 2.5 V rail in a 105°C ambient without derating panic, but the ESR limits ripple current to about 1.3 A at 100 kHz; beyond that the self-heating eats into the temperature margin.
330 µF at 2.5 V — where it fits the BOM
330 µF in a 2917 (7343 Metric) package at 2.5 V is a common bulk decoupling value for 1.8 V and 1.2 V digital rails — think FPGA core supplies, DDR termination, or POL converter outputs. The ±10% tolerance keeps the minimum capacitance above 297 µF across temperature, which is tight enough for most regulator stability criteria. The 2.5 V rating leaves 0.7 V headroom on a 1.8 V rail, which is adequate for a well-regulated supply but marginal if the rail sees 2.0 V during startup sequencing.
