220 µF at 10 V with 70 mΩ ESR — the bulk decoupling spec that drives the fit
The TPSE227M010R0070 is a 220 µF tantalum capacitor rated at 10 V in the TPS series from KYOCERA AVX, molded case, E size code (2917 / 7343 Metric footprint). The 70 mΩ ESR is the figure that governs ripple handling and transient response in a DC-DC output filter or a processor core rail — lower ESR means less self-heating and tighter voltage regulation under load steps. Surface-mount 2917 case mates with standard reflow profiles for the TPS series.
ESR and ripple — the decision number for output filtering
Compare this to a standard tantalum at 300-500 mΩ: the TPSE227M010R0070 runs cooler and holds output ripple lower for the same load transient.
