220 µF bulk decoupling for 2.5 V rails
The TPSB227M002R0600 is a molded tantalum capacitor from KYOCERA AVX's TPS series, offering 220 µF capacitance with ±20% tolerance at a rated voltage of 2.5 V. If the rail needs lower ripple, a parallel ceramic cap or a lower-ESR tantalum (e.g., 100 mOhm) is needed.
That means it can be deployed in avionics engine bays, satellite power buses, downhole drilling tools, and outdoor telecom cabinets where the ambient swings from arctic cold to engine-heat soak. The molded case provides mechanical stability and moisture resistance across that range.
1411 (3528 Metric) case — B-size footprint
Housed in the manufacturer size code B case, measuring 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. The 1411 (3528 Metric) footprint is a common tantalum capacitor land pattern; the board layout should follow the recommended pad geometry in the KYOCERA AVX TPS series application note to avoid tombstoning during reflow.
