That ESR figure is the key thermal limiter: at 47 µF and 10 V, the ripple current capability is set by the self-heating from the ESR, so a power rail with high-frequency ripple will need a capacitor with lower ESR or a parallel bank to stay within the temperature rise budget. The ±20% tolerance is standard for tantalum electrolytics — the capacitance will vary with temperature and DC bias, so for a timing or filter circuit the actual in-circuit value may be 37.6 µF to 56.4 µF at rated voltage. Plan the derating margin accordingly.
The molded case construction (Type: Molded) provides mechanical stability and moisture resistance across that span.
The capacitor uses the 1411 (3528 Metric) or 1210 case size — a common footprint across the TPS series and many other tantalum capacitor families. The dimensions are 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. The B case code (Manufacturer Size Code B) is the standard for this capacitance and voltage combination, so a replacement from another manufacturer with the same case code will typically fit the same PCB land pattern.
