The TAJW476M016RNJ: This is a surface-mount molded tantalum capacitor from the TAJ series, rated 47 µF at 16 V with ±20% tolerance. The 400 mOhm ESR is the figure that matters for ripple current handling and transient response on a power rail — a 3.3 V or 5 V supply sees the bulk decoupling cap's ESR dominate the output voltage dip during a load step. The 2312 (6032 Metric) case with a seated height of 1.50 mm fits standard 0.100-inch pitch layouts; the W size code is the standard height variant for this footprint.
Sourced through independent distribution; availability confirmed at RFQ against the BOM quantity.
