220 µF, 125 mOhm ESR — bulk decoupling for tight rails
The TPSD227M006R0125 is a molded tantalum capacitor from KYOCERA AVX's TPS series, delivering 220 µF capacitance at 6.3 V rated voltage with a 125 mOhm ESR. The low ESR keeps ripple current heating in check for power rail decoupling and filter stages in DC-DC converter output circuits.
2917 (7343 Metric) — surface-mount footprint
Housed in the standard 2917 (7343 metric) molded case, size code D, with dimensions 7.30 mm x 4.30 mm and seated height 3.10 mm max. The surface-mount package reflows on standard FR-4 with a typical 245°C peak profile; the molded body provides mechanical protection during pick-and-place and rework.
