This TPSA476M004R0500 is a molded tantalum capacitor from KYOCERA AVX, rated 47 µF at 4 V with a 500 mOhm ESR in the compact 1206 (3216 Metric) case — a common footprint for low-voltage bulk decoupling. Lifecycle status is Active — no NRND or EOL flag.
Case size and footprint fit
The 1206 (3216 Metric) case measures 3.20 mm x 1.60 mm with a seated height of 1.80 mm max — the same footprint as a standard 1206 ceramic capacitor, so it drops onto an existing PCB layout without a pad redesign. Manufacturer size code A means the case dimensions are consistent across the TPS family; the 500 mOhm ESR is the series maximum at 100 kHz and 25°C, which sets the ripple-current capability for the decoupling application.
