150 µF bulk cap for low-voltage rails
The 1.2 Ohm ESR means it handles moderate ripple current; for a 100 kHz buck converter output, the self-heating stays manageable below 500 mA RMS.
At 125°C the leakage current rises and the capacitance drifts — derate the applied voltage to 50% of rated for best reliability above 85°C.
Size B case — 3.50 mm x 2.80 mm footprint, 2.10 mm seated height. Fits the standard 1411 (3528 Metric) land pattern, also listed as 1210. The molded body is polarity-marked with a stripe on the positive end; orientation is obvious enough to hand-place without a microscope.
