Component selection — 220 µF, 10 V, 150 mOhm ESR
The TPSD227M010R0150: The 150 mOhm ESR (equivalent series resistance) governs the ripple current the part can handle before self-heating becomes a derating concern — at 220 µF and 10 V, this ESR keeps the AC ripple losses within the molded package's thermal budget for typical decoupling and bulk storage roles. The -55°C to 125°C operating range covers the full industrial temperature envelope and the upper end of automotive ambient, so the cap stays within spec in an engine-bay ECU or a rooftop telecom enclosure.
