2.2 µF at 35 V — molded tantalum for tight board profiles
This TAJT225M035RNJ is a molded tantalum capacitor from the TAJ series, rated 2.2 µF with ±20% tolerance and a 35 V working voltage. The 4.2 Ohm ESR at 25 °C is the key loss parameter — at high ripple or fast transient loads, that ESR determines the self-heating and the usable ripple current before the part derates. The 35 V rating sits well above a typical 12 V or 24 V rail — for a 12 V bus you have 2× derating margin, which is standard practice for tantalum reliability in power-supply decoupling.

The molded 1411 (3528 Metric) / 1210 case sits 1.20 mm seated height — fits under low-profile components or mezzanine boards where height is constrained.
This matters for avionics, satellite, downhole instrumentation, or outdoor telecom where the capacitor sees extreme ambient swings. The ESR curve shifts with temperature — expect higher ESR at cold and lower at hot, affecting ripple current capability at the temperature extremes.
