Capacitance, voltage, and case size
The TAJB155K035RNJ: Rated 1.5 µF at 35 V with ±10% tolerance — this is the BOM-fit number for a bulk decoupling or filter cap on a 24 V or 12 V rail with headroom for transients. Housed in a 1411 (3528 Metric) molded case, 3.50 mm x 2.80 mm footprint, seated height 2.10 mm max — the B-size code matches a standard tantalum land pattern for reflow assembly.
Temperature range and ESR
ESR is 5.2 Ohm — typical for a B-case tantalum at this voltage and capacitance; it limits ripple current handling, adequate for low-frequency decoupling but not for high-ripple switching supplies.
