The TAJD687K002SNJ: This is a molded tantalum capacitor from the TAJ series, rated 680 µF at 2.5 V with ±10% tolerance. The 200 mOhm ESR at 100 kHz means it handles ripple current without excessive self-heating — important for low-voltage rail decoupling where the ripple frequency is in the hundreds of kHz.
