220 µF bulk capacitance with a 150 mOhm ESR floor
The TPSE227K010T0150V: The 150 mOhm ESR at 100 kHz sets the ripple current capability — for a 100 kHz buck converter output, this ESR determines the output ripple voltage and the self-heating under load. The -55 to 125 °C operating range covers industrial and automotive ambient conditions without derating up to the full temperature band.
Active lifecycle — no obsolescence risk on this BOM line
For a BOM cost engineer or component engineer tracking PCN risk, this part is a stable line item without a forced migration timeline.
Footprint and layout — 2917 case with standard pad geometry
The E-size code corresponds to the standard tantalum chip footprint used across the TPS series. For a PCB layout engineer, the pad pattern follows the typical 7343-31 or 7343-43 land pattern per IPC-7351B, with the anode pad on the shorter side and the cathode marked by the stripe on the body. Reflow profile follows the standard J-STD-020 for moisture-sensitive components — the molded case does not require special handling beyond the MSL rating typical for tantalum chips.
