22 µF, 16 V, 375 mOhm ESR — what it means on your board
The TPSC226M016H0375: This is a molded tantalum capacitor from the TPS series, 22 µF ±20% at 16 V, with a 375 mOhm ESR. That ESR number tells you how much ripple current it can handle before self-heating becomes a problem — in a switching regulator output filter, lower ESR means less voltage ripple but higher AC current stress on the cap.
KYOCERA AVX lists this part as Active.
2312 (6032 Metric) — standard footprint, no surprises
The package is 6.00 mm x 3.20 mm, 2.80 mm seated height — a common C case size for molded tantalums. The footprint matches industry-standard 2312 (6032 Metric) pads, so your existing PCB layout for a C-case tantalum will accept this part without a spin.
