220 µF bulk decoupling in a 2917 footprint
The TPSD227M010H0050 is a molded tantalum capacitor from KYOCERA AVX's TPS series, delivering 220 µF capacitance at 10 V rated voltage with a 50 mOhm ESR. This combination suits it for bulk decoupling on power rails where low impedance at switching frequencies matters — the ESR directly sets the ripple current capability and the self-heating under load. The 2917 (7343 Metric) case size, size code D, fits standard reflow profiles. The ±20% tolerance is typical for tantalum electrolytics; derate the applied voltage to 50-60% of rated for reliable operation, per industry practice.
It is a fit for avionics power supplies, downhole instrumentation, satellite bus filtering, and other environments where the ambient swings beyond industrial limits. The molded construction provides mechanical stability and moisture resistance over that range.
