330 µF, 4 V, 300 mOhm ESR — bulk decoupling in a low-profile 2917 case
The TAJX337K004RNJ: This is a molded tantalum capacitor from the TAJ series, rated 330 µF at 4 V with ±10% tolerance and 300 mOhm ESR (Equivalent Series Resistance) at 100 kHz. The 2917 (7343 Metric) case measures 7.30 mm x 4.30 mm with a seated height of just 1.50 mm, making it suitable for low-profile boards where height is constrained. Higher-ESR parts run hotter under the same ripple; this one stays cooler for a given AC budget.
