47 µF in a B case — what the ESR means for your rail
The TPSB476M006R0500 packs 47 µF into a molded 1411 (3528 Metric) B case with a 500 mOhm ESR. That ESR figure sets the ripple current ceiling: at 100 kHz, the capacitor self-heats by the I²R loss, and the 125°C rating leaves headroom for a 10°C rise in a 85°C ambient — typical for a POL output filter on a 6.3 V rail.
Temperature grade and deployment fit
This covers avionics black boxes that see -40°C cold soak and 105°C internal ambient, downhole logging tools that run at 125°C, and satellite power buses where the capacitor must survive thermal cycling without derating.
